| 摘 要： | 苯乙烯、二乙烯基苯经珠状悬浮聚合制成四种不同交联度的大孔共聚体,再经氯甲基化、胺化反应制成聚N-(β-氨乙基)乙烯基苄胺树脂。后者与双(二乙胺基)氯化瞵反应得到一类新型的高分子胺基膦配位体,用它们与二-μ-氯四羰基二铑反应,制成固载化铑络合物催化剂。用所合成的催化剂进行二异丁烯的氢甲酰化反应。考察了载体交联度对催化剂性能的影响。

Preparation of a new polymeric ligand bound rhodium catalyst and its performance in hydroformylation of diisobutylene |
| |
| Abstract: | Four macroporous copolymers of styrene-divinylbenzene in the form of beads containing 1, 8, 20, 40％ of DVB respectively were made by suspension polymerization. After chloromethylation of the beads and followed by amination with ethylenediamine, poly N-(β-ethylamine) ethylbenzamide resin was prepared. This was reacted with di(dicthylamine)phosphine chloride to obtain a new type of polymeric amino phosphiine ligand, which was further reacted with Rh_2(CO)_4 Cl_2 to give four supported polymeric aminophosphine rhodium catalysts with different degrees of crosslinking.These catalysts were used in hydroformylation ot diisobutylene. The effecets of the degree of crosslinking were studied. |
