聚－γ－Ν（β－苯硫基）乙基胺丙基硅氧烷钯络合物的研究 THE SYNTHESIS AND ACTIVITY OF POLY γ Ν（ β PHENSULFIDE） ETHYLAMINOPROPYSILOXANE PALADIUM COMPLEX 林颐庚 Lin Yigeng 1 first-author 肖超渤 Xiao Chaobo 1 毛璞 Mao Pu 1 武汉大学化学系 武汉大学化学系 Department of Chemistry,Wuhan University Department of Chemistry,Wuhan University 以Ｎ－烯丙基乙醇胺为原料，经过卤化，再与苯硫酚钾反应制得Ｎ－（β－苯硫基）乙基烯丙胺，通过硅氢化反应和三甲氧基硅烷作用，然后水解固载，络合氯化钯，得到固载在二氧化硅上的聚－γ－Ｎ（β－苯硫基）乙基胺丙基硅氧烷钯络合物，并用ＸＰＳ研究了结构．选用Ⅰ－十二烯、苯乙烯、Ⅰ－癸烯、苯基烯丙基醚、烯丙基环氧丙基醚、丁烯腈、环己烯、硝基苯等８种底物进行催化加氢，以评价其催化活性．结果表明，该催化剂选择性明显．不同溶剂中，其活性顺序为：苯异丙醇＞乙醇、正己烷．该催化剂在空气中放置半年，其活性无明显变化，经简单回收可再用 The poly γ Ν（ β phensulfide）ethylaminoproylsiloxane palladium has been synthesized.The title complex displayed the higher activity for the hydrogenation of dodecene and styrene in benzene at 60℃ under an atmosphere pressure of hydrogen 85% of dodecene（10×10 -3 mol）were complerely hydrogenation with 28 mg comlex containing 0.155 mg palladium within 2.1h.palladium complex in highly air stable.It stored under air for 0.5 year was nearly as actively as freashly prepared one.The structure of palladium complex was studied by X ray photoelectron spectroscopy（XPS）.The rate of hydrogenation decrease in a variety solvent in the order:benzene, iso propanol, ethanol,hexane. The polymer complex can be easily recovered and reused. 聚－γ－Ν（β－苯硫基）乙基胺丙基硅氧烷 钯络合物 催化剂 氢化 XPS poly γ Ν（ β phensufide）ethylaminopropylsiloxane palladium complex catalyst Hydrogenation XPS O614.823 国家自然科学基金(61672102) 1996-04-01 2021-04-01 4
