本文合成了不同交联度的苯乙烯一二乙烯基苯含膦树脂球,然后与PtCl_2和SnCl_2反应得到高分子催化剂。进一步研究了它催化α-烯烃的醛化反应。结果证明,这种催化剂对正构醛具有极高的选择性(最高达95%)和很高的催化活性。本文还研究了催化剂活性和选择性与烯烃结构,树脂的交联度,催化剂组成,溶剂,反应温度和H_2/CO压力的关系。 In this paper, styrene-divinylbenzene-containing phospholipid resin beads with different degree of cross-linking were synthesized, and then reacted with PtCl_2 and SnCl_2 to obtain polymer catalysts. It is further studied that it catalyzes the hydroformylation of α-olefins. The results demonstrate that this catalyst has very high selectivity (up to 95%) and high catalytic activity to n-alkanal. The relationship between catalyst activity and selectivity and olefin structure, resin cross-linking degree, catalyst composition, solvent, reaction temperature and H 2 / CO pressure were also studied.
