摘　　要：以四甲基乙二胺-苯硫醚为双配体制备了新型铑钌加氢催化剂,研究了这种催化剂对NBR的加氢活性,主要考察了催化剂浓度以及反应温度、时间、氢气压力、胶液浓度对NBR溶液加氢性能的影响,得到了新型双金属双配体催化剂对NBR加氢的较佳工艺参数.同时在自行设计的动力学研究装置上,测试了催化剂对NBR加氢的空气稳定性,其空气稳定性优于现有的其他贵金属加氢催化剂.与几种商业化的胶的性能进行了对比,自制的HNBR产品力学性能达到了工业化产品的水平,表明这种新型催化剂具有高活性、好的选择性以及优良的实用性.A new kind of bimetallic biligand NBR hydrogenation catalyst with two ligands, tetramethylethylenediamine and phenylsulfide, was prepared in this work. The influence of catalyst, reaction temperature, time, pressure, and NBR concentrations on NBR hydrogenation were studied. The results showed higher selectivity, higher activity and lower cost of the catalyst. In addition, the stability of the bimetallic biligand catalyst was checked by a reaction equipment designed for kinetics measurement, and a longer life of this catalyst in air was achieved. The mechanical properties of HNBR product were with the commercial products of Bayer and Zeon. In conclusion, this kind of catalyst was perfect for NBR hydrogenation and of high practical value. In particular, the air stability of this catalyst was better than others.
