| 摘 要： | 以含磷、氢、氧和硫元素的化合物为配体，分别与三氯化铑水合物形成配位催化剂，并以此对NBR进行加氢。结果表明：以含磷、氢、氮和硫元素的化合物为配体与铑金属离子的配位形成的催化剂对NBR加氢具有不同的活性；研制出用于NBR加氢的新型双配体催化剂（Rh－N－T），其加氢度可达96％以上，而且具有良好的空气稳定性。

| Abstract: | Various phosphorous, nitrogen,oxygen, and sulfur compounds were used as ligands on rhodium chloride to form homogeneous catalysts for NBR hydrogenation. These catalysts showed inferior catalytic activity compared to the Wilkinson catalyst. New types biligand of rhodium catalyst system for hydrogenation of NBR were discussed.Two examples of new catalyst described here in contain nitrogen and sulfur compounds as their two ligands. Rh-N-T biligand catalyst exhibited a catalytic activity equal to that of the Wilkinson catalyst in addition to having the advantage of being relatively stable in air. |
