摘　　要：研究制备了聚γ氨丙基硅氧烷钯络合物催化剂ＰＣＡＬ，用于丁炔二醇（ＢＹ）的催化半氢化，半氢化产物丁烯二醇（ＢＥ）收率高达９５％。在相同试验条件下用Ｌｉｎｄｌａｒ催化剂作了催化半氢化丁炔二醇的对比，发现二者有相同的催化效果，就生成ＢＥ的选择性和催化剂寿命而言，ＰＣＡＬ催化剂具有更多优点。The preparation of the poly γ amino propylsiloxane Pd complex catalyst(PCAL) used for selective semihydrogenation of butynediol(BY) has been reported in this paper. Comparison is made between the PCAL and the well known Lindlar's catalyst in a semihydrogenation reaction of BY. The result shows the catalyst PCAL, having a higher yield of butenediol(BE), above 95%, is superior to Lindlar's catalyst in its reproducibility, and in the selectivity of main product BE, as well.
