摘　　要：合成了水溶性有机膦配体三-(对苯氧基-聚氧乙烯醚)-膦(TPPP),制备了它的含铑配合物,并将其成功地用于丁腈橡胶(NBR)的选择性催化加氢反应,顺利地合成了氢化丁腈橡胶(HNBR).经测定,催化剂对丁腈橡胶的选择性催化加氢率达65%以上;产物HNBR中金属铑含量未被检出(w<0.1mg/kg);水相中金属铑的回收率按质量分数计算大于96%,显示了水/有机两相膦铑催化剂在催化氢化丁腈橡胶中良好应用的前景.The water-soluble ligand tri-(p-phenoxyl-polyoxyethylene ether)-phosphine and it's rhodium complex was synthesized.The rhodium complex has been successfully used on the selective catalytic hydrogenation of nitrile-butadiene rubber (NBR),and the target product(HNBR) was obtained.The rate of hydrogenation of NBR reached 65.03%,the total recovery of metal rhodium from the water phase was more than 96% and no any rhodium was detected in HNBR (<0.1?mg/kg).The fact shows that the phosphine rhodium complex is an efficient catalyst for the hydrogenation of NBR.
