Description
Al2O3:(n)SiO2
式中、nは10〜50の値を有する。
ここで、Qは、N,N−ジメチルピペリジニウムカチオンを含み、Mは、カリウムおよびナトリウムとカリウムとの組み合わせからなる群から選択される第1族金属である。
以下の用語は、本明細書を通して使用され、他に示されない限り以下の意味を有する。
一般に、分子ふるいSSZ−105は、(a)以下の成分:(1)ケイ素酸化物の少なくとも1種の供給源;(2)アルミニウム酸化物の少なくとも1種の供給源;(3)カリウム、ならびに、ナトリウムおよびカリウムの組み合わせからなる群から選択される、第1族金属(M)の少なくとも1種の供給源;(4)水酸化物イオン;(5)N,N−ジメチルピペリジニウムカチオン;および(6)水を含む反応混合物を調製する工程;ならびに(b)前記反応混合物を、この分子ふるいの結晶を形成するのに十分な結晶化条件にかける工程によって調製される。
ここで組成変数MおよびQは、本明細書中で上述されているとおりである。
本明細書に開示された分子ふるいの結晶化は、例えばポリプロピレンジャーまたはテフロン(登録商標)ライナーまたはステンレススチール製のオートクレーブのような適当な反応容器中で静的、タンブルまたは撹拌条件下で、125℃〜200℃(例えば140℃〜180℃)の温度で、この使用される温度で結晶化が起こるのに十分な時間、例えば1日〜28日の間行うことができる。結晶化は、通常、閉鎖系にて、自己発生圧力で行われる。
分子ふるいSSZ−105は、ERI及びLEV結晶構造の連晶成長である。2つの純粋な材料のサンプルを混合することによって調製された2相ERIおよびLEVの物理的混合物は、分子ふるいSSZ−105として定義されない。
ここで、組成変数QおよびMは、本明細書にて上述されたとおりである。
Al2O3:(n)SiO2
式中、nは、少なくとも10の値(例えば、10〜50、10〜45、10〜40、10〜35、10〜30、10〜25、12〜50、12〜45、12〜40、12〜35、12〜30、12〜25、15〜50、15〜45、15〜40、15〜35、15〜30、または15〜25)である。
分子ふるいSSZ−105は、気体および液体を乾燥させるため;サイズおよび極性特性に基づく選択的分子分離のため;イオン交換体として;化学物質キャリアとして;ガスクロマトグラフィーにおいて;有機転化反応における触媒として使用することができる。適切な触媒使用の例には、酸素化物(oxygenates)の1つ以上のオレフィンへの接触転化、モノアルキルアミンおよびジアルキルアミンの合成、および窒素酸化物の接触還元が含まれる。
分子ふるいSSZ−105を用いてガスを分離することができる。例えば、天然ガスから二酸化炭素を分離するためにそれを使用することができる。典型的には、この分子ふるいは、ガスを分離するために使用される膜の成分として用いられる。このような膜の例は、米国特許第6,508,860号に開示されている。
分子ふるいSSZ−105は、有機酸素化物を1種以上の軽質オレフィン、特にエチレンおよび/またはプロピレンに接触転化するのに有用である。本明細書で使用される「酸素化物」(“oxygenates”)という用語は、脂肪族アルコール、エーテル、カルボニル化合物(アルデヒド、ケトン、カルボン酸、カーボネートなど)、およびヘテロ原子を含む化合物、例えばハロゲン化物、メルカプタン、硫化物、アミン、並びにそれらの混合物を含むものとして定義される。脂肪族部分は、通常1〜10個の炭素原子、例えば1〜4個の炭素原子を含む。
分子ふるいSSZ−105は、メチルアミンまたはジメチルアミンを製造するための触媒中で使用することができる。ジメチルアミンは、一般に、シリカ−アルミナ触媒の存在下でメタノール(および/またはジメチルエーテル)とアンモニアとを連続的に反応させることによって工業的な量で調製される。反応物質は、典型的には、300℃〜500℃の温度で、かつ高められた圧力にて気相中で組み合わせられる。このようなプロセスは、米国特許第4,737,592号に開示されている。
分子ふるいSSZ−105は、ガス流中の窒素酸化物の選択的還元のために使用することができる。このプロセスでは、分子ふるいSSZ−107を含む触媒および還元剤の存在下で、窒素酸化物(NOx)を含むガス流を選択的に還元する。窒素酸化物(主にNOおよびNO2)は、還元剤が酸化されている間にN2に還元される。アンモニアが還元剤である場合、N2も酸化生成物である。理想的には、唯一の反応生成物は水およびN2であるが、NH3の一部は通常空気でNOまたはN2Oに酸化される。
分子ふるいSSZ−105は、炭化水素トラップとして、特に炭化水素燃料の燃焼に伴う排出物を低減するためにも使用することができる。
