showing typical deactivation or leaching phenomena. The catalyst is based on a bulky, rigid, and robust silsesquioxane‐modified PPh3 ligand, and combines efficient recovery with high activity and selectivity.
顺其自然:均相催化剂回收可用于连续流纳滤反应器(见图)中醛的生产,该反应器可运行长达两周的空前时间,而不会出现典型的失活或浸出现象。该催化剂基于庞大,刚性且坚固的倍半硅氧烷改性的PPh 3配体,将高效回收率与高活性和选择性结合在一起。
