Description
本発明は、プロパンジオールの製造方法に関する。さらに詳しくは、本発明は、グリセリンを原料とし、これを酸、水素化触媒及び必要により溶媒の存在下にて水素化することによって1,3−プロパンジオールの収率の高いプロパンジオールの製造方法に関する。 The present invention relates to a method for producing propanediol. More specifically, the present invention relates to a process for producing propanediol with a high yield of 1,3-propanediol by using glycerin as a raw material and hydrogenating it in the presence of an acid, a hydrogenation catalyst and, if necessary, a solvent. About.
プロパンジオール類は、溶媒、ポリエステル原料として極めて重要である。そのため、従来から、1,2−プロパンジオールについてはプロピレンの部分酸化による製造技術、1,3−プロパンジオールについては、糖の発酵による製造技術が実用化されている。 Propanediols are extremely important as solvents and polyester raw materials. Therefore, conventionally, for 1,2-propanediol, a production technique by partial oxidation of propylene and for 1,3-propanediol, a production technique by fermentation of sugar has been put to practical use.
一方、グリセリンは油脂類のエステル交換反応によるBDF(バイオディーゼルフューエル)製造の際の副産物として世界的な供給過剰が予想されている物質である(非特許文献1参照)。したがって、グリセリンを原料としたプロパンジオールの製造方法が確立されれば、その産業的な意義は大きいと考えられる。 On the other hand, glycerin is a substance that is expected to be supplied globally as a by-product in the production of BDF (biodiesel fuel) by transesterification of fats and oils (see Non-Patent Document 1). Therefore, if a method for producing propanediol using glycerin as a raw material is established, it is considered that its industrial significance is great.
現在までに知られているグリセリンからのプロパンジオールの製造方法としては、微生物を用いる発酵法(非特許文献2,3参照)と、触媒を用いる水素化分解法(非特許文献4,5及び特許文献1参照)が知られている。
Known methods for producing propanediol from glycerin to date include fermentation methods using microorganisms (see Non-Patent
しかし、発酵法による製造においては、1,3−プロパンジオールの収率が70%近くに達するという利点はあるが、反応速度が遅いため、巨大な発酵槽が必要となる他、副生成物による阻害のため最終的な水溶液中の生成物濃度が7%程度と低いことから、水や未反応グリセリンから1,3−プロパンジオールを分離、精製するためのコストが大きくなるという問題がある。 However, in the production by the fermentation method, there is an advantage that the yield of 1,3-propanediol reaches nearly 70%. However, since the reaction rate is slow, a huge fermenter is required, and it depends on by-products. Since the final product concentration in the aqueous solution is as low as about 7% due to inhibition, there is a problem that the cost for separating and purifying 1,3-propanediol from water and unreacted glycerin increases.
これに対し、触媒を用いる水素化分解法は、発酵法のように巨大な設備が必要でなく、一般に有機溶媒中で反応が行われるので、生成物の分離精製が容易である点で有利である。しかし、水素化分解法ではその一方で収率が非常に低いという問題がある。例えば、担持ロジウム触媒の場合(非特許文献1参照)、1,3−プロパンジオールの収率は最高4%、1,2−プロパンジオールの収率は最高15%である。また、担持ルテニウム触媒の場合(非特許文献1参照)、1,3−プロパンジオールの収率は最高0.6%、1,2−プロパンジオールの収率は最高18%である。また、ルテニウム錯体触媒の場合(特許文献1参照)、1,3−プロパンジオールの収率は4.6%である。
このように、1,3−プロパンジオールは、ポリプロピレンテレフタレート(PPT)の原料となるため、グリセリンからの製造が強く要請されているものであるものの、工業的に有利な接触水素化分解による製造方法では、5%以下の収率でしか得られていない。 Thus, since 1,3-propanediol is a raw material for polypropylene terephthalate (PPT), production from glycerin is strongly demanded, but an industrially advantageous production method by catalytic hydrocracking However, it is obtained only in a yield of 5% or less.
本発明は、かかる実状を背景に、余剰産物とされていたグリセリンを原料とし、これを水素化分解法によりプロパンジオール、特に1,3−プロパンジオールをより高収率に製造するためになされたものである。 The present invention has been made in order to produce propanediol, particularly 1,3-propanediol, in a higher yield by hydrocracking the raw material from glycerin, which has been regarded as a surplus product, in the background of the actual situation. Is.
かくして、本発明者は、このような課題に対して、まず通常のオートクレーブを用いて、水素化触媒、酸、及び溶媒からなる触媒系の存在下で、グリセリンを水素化分解させたが、プロパンジオールは少量しか得られず、大部分のグリセリンが回収される結果となった。ところが、同じ原料を用いてガラス内管付きのオートクレーブで反応を行った場合には、ガラス内管とオートクレーブ壁面の間のわずかの隙間に反応後の反応液のかなりの部分が存在しており、驚くべきことに、その反応液中に1,2−プロパンジオール、n−プロパノールとともに、1,3−プロパンジオールが高収率で生成していることが判明した。これは、反応中に溶媒とグリセリン水素化反応生成物、及び水がガラス管外に留去したため、ガラス管内の触媒がスラリー状になり、グリセリンの水素化活性が向上したためと考えられた。本発明はこの知見に基づいて完成させたものであり、溶媒量を少なくしたスラリー触媒系を用いることにより、グリセリンの反応性を向上させるとともに、生成したプロパンジオールと水を連続的に反応系外に抜き出しながらグリセリンを水素化分解させることにより、水による反応阻害とn−プロパノールの生成が抑制され、プロパンジオール類が高収率で得られるものと推察される。 Thus, in order to solve such problems, the present inventor first hydrocracked glycerin in the presence of a catalyst system comprising a hydrogenation catalyst, an acid, and a solvent using an ordinary autoclave. Only a small amount of diol was obtained, resulting in the recovery of most of the glycerin. However, when the reaction is carried out in an autoclave with a glass inner tube using the same raw material, a considerable portion of the reaction solution after the reaction exists in a slight gap between the glass inner tube and the autoclave wall surface, Surprisingly, it was found that 1,3-propanediol was produced in a high yield together with 1,2-propanediol and n-propanol in the reaction solution. This was thought to be because the solvent, glycerin hydrogenation reaction product, and water were distilled out of the glass tube during the reaction, so that the catalyst in the glass tube became a slurry and the hydrogenation activity of glycerin was improved. The present invention has been completed based on this finding. By using a slurry catalyst system with a reduced amount of solvent, the reactivity of glycerin is improved and the produced propanediol and water are continuously removed from the reaction system. By hydrocracking glycerin while being extracted, it is surmised that reaction inhibition by water and generation of n-propanol are suppressed, and propanediols can be obtained in high yield.

Item 7.
グリセリンの水素化分解によるプロパンジオールの製造は公知であり、その反応機構は下記のスキームにより示される。この一段の反応により、1,3−プロパンジオール、1,2−プロパンジオール、及びn−プロパノールが生成する。 Production of propanediol by hydrogenolysis of glycerin is known, and the reaction mechanism is shown by the following scheme. This one-step reaction produces 1,3-propanediol, 1,2-propanediol, and n-propanol.
従来のグリセリンを水素化分解してプロパンジオールを製造する方法では水素化分解のためグリセリンに加え常温で固体の酸、水素化触媒及び溶媒が必須であり、これによりプロパンジオールを生成するものであるが、得られる1,3−プロパンジオールの収率は非常に低いものであった。本発明ではこの反応系において、溶媒の量を非常に少量とするか使用しないことを特徴とする。すなわち、本発明では、グリセリン、常温で固体の酸及び水素化触媒、必要に応じてここに溶媒を加え、この際、酸及び水素化触媒の合計重量(g)がグリセリン及び溶媒の合計容量(mL)の1/15〜10倍であることが必須であり、好ましくは1/15〜3倍である(なお、触媒金属が担体に担持された水素化触媒を使用する場合は、触媒金属重量と担体重量の合計を水素化触媒の重量とする)。液体であるグリセリン及び溶媒、特に溶媒の量を少量とすることによって1,3−プロパンジオールの収率が向上する。さらに、本発明では、溶媒として環状アミドを使用することによって1,3−プロパンジオールの収率が高まる。 In the conventional method for producing propanediol by hydrocracking glycerol, an acid, a hydrogenation catalyst and a solvent which are solid at room temperature in addition to glycerol are essential for hydrocracking, thereby producing propanediol. However, the yield of 1,3-propanediol obtained was very low. The present invention is characterized in that the amount of the solvent is very small or not used in this reaction system. That is, in the present invention, glycerin, an acid that is solid at room temperature and a hydrogenation catalyst, and if necessary, a solvent is added thereto. At this time, the total weight (g) of the acid and the hydrogenation catalyst is the total capacity of glycerin and the solvent ( It is essential that it is 1/15 to 10 times that of mL), preferably 1/15 to 3 times (in the case of using a hydrogenation catalyst in which the catalyst metal is supported on the support, the weight of the catalyst metal And the weight of the carrier is the weight of the hydrogenation catalyst). The yield of 1,3-propanediol is improved by reducing the amount of glycerin and a solvent, particularly a solvent, in a small amount. Furthermore, in the present invention, the yield of 1,3-propanediol is increased by using a cyclic amide as a solvent.
プロパンジオールは、例えば、オートクレーブ内に所定量のグリセリン、酸、水素化触媒、必要に応じて溶媒を仕込み、加熱することによって製造できる。本発明において、溶媒は必須ではないが、少量であれば有用であり、1種単独又は2種以上組み合わせて使用できる。溶媒の例は、環状アミド、スルホラン、DMSO等である。溶媒は、沸点が150℃以上のものが好ましく、250℃以上のものがより好ましい。好ましい溶媒は環状アミドであり、その例としては、1,3−ジメチルイミダゾリジノン、N−メチルピロリジノンなどが挙げられる。環状アミドの中でも、環を構成する元素のうちの一つ以上が窒素である環状アミドが好ましい。 Propanediol can be produced, for example, by charging a predetermined amount of glycerin, acid, hydrogenation catalyst and, if necessary, a solvent in an autoclave and heating. In the present invention, a solvent is not essential, but a small amount is useful and can be used alone or in combination of two or more. Examples of the solvent are cyclic amide, sulfolane, DMSO and the like. The solvent preferably has a boiling point of 150 ° C. or higher, more preferably 250 ° C. or higher. A preferred solvent is a cyclic amide, and examples thereof include 1,3-dimethylimidazolidinone and N-methylpyrrolidinone. Among the cyclic amides, cyclic amides in which one or more of the elements constituting the ring are nitrogen are preferable.
上記溶媒の使用量は、グリセリン1重量部に対して0〜20重量部、好ましくは0.5〜10重量部、より好ましくは1〜5重量部、よりいっそう好ましくは1〜3重量部である。溶媒が上記の範囲にある場合、プロパンジオール、特に1,3−プロパンジオールの収率の点で有利である。また、上記の範囲ではグリセリン、溶媒、酸及び触媒はスラリー状態になることが多い。 The amount of the solvent used is 0 to 20 parts by weight, preferably 0.5 to 10 parts by weight, more preferably 1 to 5 parts by weight, and still more preferably 1 to 3 parts by weight with respect to 1 part by weight of glycerin. .

本発明の製造方法において、反応は水素の存在下で行えばよく、水素圧は特に限定されないが、好ましくは10〜150気圧、より好ましくは50〜100気圧である。また、反応温度は、好ましくは100〜300℃、より好ましくは160〜220℃であり、反応時間は、好ましくは1〜48時間、より好ましくは10〜24時間である。 In the production method of the present invention, the reaction may be carried out in the presence of hydrogen, and the hydrogen pressure is not particularly limited, but is preferably 10 to 150 atm, more preferably 50 to 100 atm. Moreover, reaction temperature becomes like this. Preferably it is 100-300 degreeC, More preferably, it is 160-220 degreeC, Reaction time becomes like this. Preferably it is 1-48 hours, More preferably, it is 10-24 hours.
本発明の製造方法では、反応中に生成物を連続的に系外に排出して回収することが好ましい。目的物であるプロパンジオールの沸点がグリセリンの沸点より低いため、プロパンジオールを系外に排出することによって、二次生成物であるn−プロパノールの生成が抑制され、プロパンジオールの収率が向上するためである。 In the production method of the present invention, it is preferable that the product is continuously discharged out of the system and recovered during the reaction. Since the boiling point of propanediol, which is the target product, is lower than the boiling point of glycerin, the production of n-propanol, which is a secondary product, is suppressed by discharging propanediol out of the system, and the yield of propanediol is improved. Because.
上記のグリセリン、酸、水素化触媒、溶媒を加圧及び加熱可能な反応器に仕込み、加熱することによってプロパンジオールを製造できる。例えばガラス内筒を有するオートクレーブ中に水素化触媒、酸、溶媒及びグリセリンを仕込み、反応条件を例えば水素初圧80気圧、反応温度170℃に設定し、スラリー状の反応物を攪拌しながら所定時間反応させる。反応中に生成物と溶媒の一部はガラス内筒の外側に留出する。この留出により生成物は連続的に反応系外に排出されることとなるが、生成物を反応系外に排出する手段はこれに限定されない。反応後、得られる生成物から所望のプロパンジオールを分離する。反応器の一例を図1に示す。 Propanediol can be produced by charging the glycerin, acid, hydrogenation catalyst, and solvent in a reactor capable of being pressurized and heated and heating. For example, a hydrogenation catalyst, acid, solvent and glycerin are charged into an autoclave having a glass inner cylinder, the reaction conditions are set to, for example, an initial hydrogen pressure of 80 atm and a reaction temperature of 170 ° C., and the slurry-like reactant is stirred for a predetermined time. React. During the reaction, a part of the product and the solvent distills outside the glass inner tube. The product is continuously discharged out of the reaction system by this distillation, but means for discharging the product out of the reaction system is not limited to this. After the reaction, the desired propanediol is separated from the resulting product. An example of the reactor is shown in FIG.
グリセリンの水素化によって生成したプロパンジオールは1,2−プロパンジオールと1,3−プロパンジオールの混合物である。1,2−プロパンジオールと1,3−プロパンジオールとを分離する場合、蒸留、各種クロマトグラフィー分離などの公知の方法により分離精製することができる。 Propanediol produced by hydrogenation of glycerin is a mixture of 1,2-propanediol and 1,3-propanediol. When 1,2-propanediol and 1,3-propanediol are separated, they can be separated and purified by known methods such as distillation and various chromatographic separations.
本発明によれば、グリセリンを水素化触媒により水素化してプロパンジオールを生成する方法において、従来より相対的に非常に高い収率でプロパンジオール、特に1,3−プロパンジオールを製造することができる。 According to the present invention, in a method for producing propanediol by hydrogenating glycerin with a hydrogenation catalyst, it is possible to produce propanediol, particularly 1,3-propanediol, in a relatively high yield compared to conventional methods. .
以下、本発明を実施例等により詳細に説明するが、本発明はこれら実施例に限定されるものではない。 EXAMPLES Hereinafter, although an Example etc. demonstrate this invention in detail, this invention is not limited to these Examples.
実施例1
縁を外に開いてオートクレーブ内壁との隙間を小さくした試験管様の形状をしたガラス内管を備えた30mL容のオートクレーブ中に、グリセリン約3mmol(0.216mL)、所定量(0、0.5、1、2mL)の溶媒である1,3−ジメチルイミダゾリジノン(DMI)、タングステン酸0.2mmol(0.049g)、活性炭に白金を担持させた触媒0.039g(白金0.01mg−atom)を仕込んで、オートクレーブの蓋を閉めた後、水素ガス(室温で80気圧)加圧下、170℃で18時間反応を行った。オートクレーブ内に生成している1,3−プロパンジオール、1,2−プロパンジオール及びn−プロパノールをガスクロマトグラフィーで定量分析し、グリセリンに対する収率を図2に示した。
Example 1
In a 30 mL autoclave equipped with a glass inner tube shaped like a test tube with the edge opened to the outside and the gap with the inner wall of the autoclave being reduced, about 3 mmol (0.216 mL) of glycerin, a predetermined amount (0, 0. 5,1,2 mL) solvent 1,3-dimethylimidazolidinone (DMI), tungstic acid 0.2 mmol (0.049 g), activated carbon supported platinum 0.039 g (platinum 0.01 mg- atom) and the autoclave cover was closed, followed by reaction at 170 ° C. for 18 hours under pressure of hydrogen gas (80 atm at room temperature). 1,3-propanediol, 1,2-propanediol and n-propanol produced in the autoclave were quantitatively analyzed by gas chromatography, and the yield relative to glycerin is shown in FIG.
溶媒0.5mLを用いた場合には、原料グリセリン基準で1,3−プロパンジオール0.7mmol(23%)、1,2−プロパンジオール0.6mmol(19%)、n−プロパノール0.2mmol(5%)が生成していた。また、反応溶液を液体クロマトグラフィーにより分析したところ、1.1mmol(34%)のグリセリンが未反応であることが分かった。図2から、溶媒を使用しない場合には、n−プロパノールの生成量が増大してグリセリンの回収率が低下(5%)し、溶媒量が1mLより多い場合には、生成物の収率が低下して未反応のグリセリンが多くなることが分かった。 When 0.5 mL of the solvent was used, 1,3-propanediol 0.7 mmol (23%), 1,2-propanediol 0.6 mmol (19%), n-propanol 0.2 mmol (based on the raw material glycerin) 5%) was produced. Moreover, when the reaction solution was analyzed by liquid chromatography, it was found that 1.1 mmol (34%) of glycerin was unreacted. From FIG. 2, when the solvent is not used, the production amount of n-propanol is increased and the recovery rate of glycerin is decreased (5%). When the solvent amount is more than 1 mL, the yield of the product is increased. It was found that the amount of unreacted glycerin decreased and increased.
実施例2
ガラス内管を備えていない30mL容のオートクレーブを使用したこと以外は実施例1と同様にしてグリセリンの水素化反応を行い生成物の定量を行った。なお、本例ではガラス内管を利用していないため、生成物は反応系外へ除去されることはない。結果を図3に示す。1,3−プロパンジオールの収率は9〜15%と従来技術に比べて高かった。図2と図3の比較により、ガラス内管があり生成物が反応系から除去される場合には、ガラス内管がなく生成物が反応系から除去されない場合に比べて、1,3−プロパンジオールの最大収率が1.5倍以上であることが理解できる。生成物を反応系外へ除去することによって収率が向上することが示された。
Example 2
The product was quantified by hydrogenating glycerin in the same manner as in Example 1 except that a 30 mL autoclave without an inner glass tube was used. In this example, since the glass inner tube is not used, the product is not removed out of the reaction system. The results are shown in FIG. The yield of 1,3-propanediol was 9-15% higher than that of the prior art. By comparing FIG. 2 and FIG. 3, when there is a glass inner tube and the product is removed from the reaction system, 1,3-propane is present compared to when there is no glass inner tube and the product is not removed from the reaction system. It can be seen that the maximum yield of diol is 1.5 times or more. It was shown that the yield was improved by removing the product out of the reaction system.
実施例3
溶媒、酸及び触媒を下記表1に示すものに代え、溶媒量を0.5mLとし、触媒金属量を0.01mg−atomに統一した(担体込みの触媒量としては7〜39mgになる)こと以外は実施例1と同様にしてグリセリンの水素化反応を行い生成物の定量を行った。結果を表1に示す。表中、PDOはプロパンジオール、n-Pはn−プロパノール、DMIは1,3−ジメチルイミダゾリジノン、NMPはN−メチルピロリジノン、H2WO4はタングステン酸を示す。
Example 3
The solvent, acid, and catalyst are replaced with those shown in Table 1 below, the solvent amount is 0.5 mL, and the catalyst metal amount is unified to 0.01 mg-atom (the catalyst amount including the support is 7 to 39 mg). Except for the above, the hydrogenation reaction of glycerin was performed in the same manner as in Example 1 to quantify the product. The results are shown in Table 1. In the table, PDO represents propanediol, nP represents n-propanol, DMI represents 1,3-dimethylimidazolidinone, NMP represents N-methylpyrrolidinone, and H 2 WO 4 represents tungstic acid.
比較例1
酸を下記表2に示すものに代え、溶媒量を0.5mLとしたこと以外は実施例1と同様にしてグリセリンの水素化反応を行い生成物の定量を行った。結果を表2に示す。表中、Sc(Tf)3はスカンジウムトリフレートを示し、その他は表1と同様である。また、BF3はメタノールコンプレックスを用いた。
Comparative Example 1
The acid was replaced with the one shown in Table 2 below, and the amount of the solvent was changed to 0.5 mL, and the hydrogenation reaction of glycerin was performed in the same manner as in Example 1 to quantify the product. The results are shown in Table 2. In the table, Sc (Tf) 3 represents scandium triflate, and the others are the same as in Table 1. Further, BF 3 was used methanol complex.
表1及び表2の比較より、酸はプロトン供与能の高い固体酸が好ましいことが理解される。 From the comparison of Table 1 and Table 2, it is understood that the acid is preferably a solid acid having a high proton donating ability.
