苯乙烯、二乙烯基苯经悬浮共聚制成珠状、大孔共聚体(交联度8％,孔径r=3.0×10~2,比表面积25M~2/g,粒度0.2—0.4mm),再经氯甲基化、膦化或胺化等功能基反应制成聚乙烯苄基二苯基膦和八种聚乙烯苄胺树脂。用这些聚合物配位体和二-μ-氯四羰基二铑[Rh_2(CO)_4Cl_2]反应,制成九种聚合物键铑催化剂。测定了二-μ-氯四羰基二铑、九种聚合物配位体和聚合物键铑催化剂的红外光谱。比较了聚合物膦、胺二类配体催化剂的活性及N-取代基对聚合物苄胺-铑催化剂活性的影响。
Styrene and divinylbenzene were made into beads by suspension copolymerization. The macroporous interpolymer (8% crosslinking degree, pore size r = 3.0 × 10 ~ 2, specific surface area 25M ~ 2 / g, particle size 0.2 ~ 0.4mm) Then by chloromethylation, phosphonation or amination and other functional groups made of polyvinylbenzyl diphenylphosphine and eight kinds of polyethylene benzylamine resin. Nine polymer bond rhodium catalysts were made using these polymer ligands and di-μ-chlorotetralarbonyl rhodium [Rh_2 (CO) _4Cl_2]. Infrared spectra of di-μ-chlorotetralarbonyl rhodium, nine polymer ligands and polymer-bound rhodium catalysts were determined. The effects of N-substituents on the activity of polymer benzylamine-rhodium catalysts were compared.
