Abstract
Description
C2〜C8オレフィン類を含むガス供給混合物を、合成ガスとともに、多孔質セラミック材料でできた支持体上を通過させるが、ここで、前記触媒系が、元素周期律表の第8又は第9族の金属、少なくとも1の有機リン含有配位子、安定剤、及び場合によりイオン性液体を含み、不均一化されていること、かつ、
前記支持体はセラミック材料のブロックであるモノリスであり、前記支持体のセラミック材料と同一又は異なるセラミック材料でできたウォッシュコートが塗布されること、
で特徴付けられる、方法である。
支持体として、長さ約20cm、直径約25mmの炭化ケイ素のモノリスを用いた。当該支持体は多孔質であり、ウォッシュコート(SiO2)で前処理した。当該支持体には、直径が約3mmであるチャネル31があった。当該支持体を反応器にいれて、Rh(acac)(CO)2、ビスフェフォス(リガンド)、ビス(2,2,6,6‐テトラメチル‐4‐ピペリジル)セバケート(安定剤)、1‐エチル‐3‐メチルイミダゾリウムビス(トリフルオロメタンスルホニル)イミド([EMIM][NTf2]/イオン性液体)及び溶媒としてジクロロメタンを含む触媒溶液と不活性環境(グロ−ブボックス)中で混合して調製して塗布した。このため、反応器を窒素でパージした後、触媒溶液をわずかに過圧して反応器に導入した。放出及び蒸発によって反応器から溶媒を除去した後、支持体上で不均一触媒系をヒドロホルミル化に用いた。
