及び揮発分を駆逐後炭化することを特徴とする等方性カ
ーボンの製造法に関する。The present invention also relates to a method for producing isotropic carbon, which comprises carbonizing after expelling volatile matter.
一般に、木材や鼾殻等の非溶融性物質の炭化物は等方性
のカーボンを与えるが、石炭系ピッチや石油系ピッチ等
の溶融性物質は異方性の炭化物を与えることが知られて
いる。In general, carbides of non-melting materials such as wood and grasshopper shells give isotropic carbon, but melting materials such as coal pitch and petroleum pitch are known to give anisotropic carbides. .
しかるに、本発明者らは後者の物質からもアルカリ金属
の存在下において加熱炭化することによ・す、高収率で
等方性カーボンを生成させることができることを発見し
、本発明を完成した。However, the present inventors have discovered that isotropic carbon can be produced in high yield from the latter substance by heating and carbonizing it in the presence of an alkali metal, and have completed the present invention. .
しかも。本発明による等方性カーボンはこれ迄に知られ

次に本発明の原理と方法について説明する。Next, the principle and method of the present invention will be explained.
一般に有機物が炭化する過程において、分解、脱水・脱
水素、環化、縮合、重合等の化学反応が；溶融状態で進
行した場合には、後処理として２５００℃以上の黒鉛化
処理を施すと異方性にすぐれた黒鉛を与える。Generally, in the process of carbonization of organic substances, chemical reactions such as decomposition, dehydration/dehydrogenation, cyclization, condensation, and polymerization proceed in a molten state, and if they proceed in a molten state, graphitization treatment at a temperature of 2500°C or higher may be applied as a post-treatment. Provides graphite with excellent orientation.
これに対して、アルカリ金属（カリウム、ナトリウム等
）を触媒とした場合の炭化過程では１００〜２００℃で
一旦溶融状態、を経るが、その縮合、集合、脱水系等の
反応が急速に進行し、７，８Ｍ平面芳香族化合物となり
不融状態となる。On the other hand, in the carbonization process when an alkali metal (potassium, sodium, etc.) is used as a catalyst, it is once in a molten state at 100 to 200°C, but reactions such as condensation, aggregation, and dehydration proceed rapidly. , a 7,8M planar aromatic compound and becomes infusible.
このため、２５００℃以上の黒鉛化処理によっても結晶
の成長や分子の配向がほとんど進行せず、したがって等
方性カーボンを生成；するものと考えられる。For this reason, it is thought that even by graphitization treatment at 2500° C. or higher, crystal growth and molecular orientation hardly progress, and therefore isotropic carbon is produced.
アルカリ金属の活性は。カリウム〉ナトリウム〉リチウ
ムの順序の強力な触媒作用を有する。What is the activity of alkali metals? It has a strong catalytic effect in the order of potassium>sodium>lithium.
触媒を均一に分散させることは、ヘキサン、ジグライム
等の溶媒を使用すれば可能である。Uniform dispersion of the catalyst is possible by using a solvent such as hexane or diglyme.
さらに溶媒の沸点付近において短時ｉ間保持することに
よって、電荷移動錯体の形成を促進し、ある程度の縮合
を進行させればアルカリ金属の使用量を低減しても高い
炭素収率が可能となる。Furthermore, by holding the solvent near the boiling point for a short period of time, the formation of a charge transfer complex is promoted, and if condensation progresses to a certain extent, a high carbon yield can be achieved even if the amount of alkali metal used is reduced. .
すなわち加熱手段として３００℃以下の温度で加熱し、
さらに３００℃以上の高温加熱することにより、原料中
に触媒が均一に分散し好ましい結果が得られる。That is, heating at a temperature of 300°C or less as a heating means,
Further, by heating at a high temperature of 300° C. or higher, the catalyst is uniformly dispersed in the raw material, and favorable results can be obtained.
但し溶媒を使用しなくても炭化は進行する。However, carbonization proceeds even without using a solvent.

第１表に示す。**Next, Table 1 shows the yield and properties of carbon materials (isotropic carbon) obtained from various raw materials.
この炭素材の特徴は極めて小さい表面積と結晶径にあり
、不侵透性炭素材への応用が考えられる。This carbon material is characterized by its extremely small surface area and crystal size, and its application as an impermeable carbon material is considered.
