聚-γ-N(β-丁硫基乙基)胺丙基硅氧烷铂络合物的合成及其催化性能的研究

The Synthesis and Catalytic Activity of Poly γ N(β Butylsulfide) Ethylaminopropylsiloxane Platinum Complex

以丙烯胺和氯乙醇为原料，合成了Ｎ－烯丙基乙醇胺；经过卤化，再与丁硫醇钠反应，制得Ｎ－（β－丁硫基乙基）烯丙胺；经过硅氢化，水解固载，络合Ｋ２ＰｔＣｌ４，得到固定在二氧化硅上的聚－γ－Ｎ（β－丁硫基乙基）胺丙基硅氧烷铂络合物，并用ＸＰＳ研究了其结构．选用１－十二烯、１－癸烯、氯代十一烯、苯基烯丙醚、苯丙烯、环己烯、丁烯腈等７种烯烃为底物，与三乙氧基硅烷进行硅氢加成反应，用铂络合物作为催化剂，考察了铂络合物的催化活性和产物的选择性．表明硅氢化速度随温度的增加而增加．铂络合物在空气中暴露半年不影响其活性。

The poly γ N(β butylsulfide)ethylaminopropylsiloxane platinum complex has been synthesized.The title complex was found to bequite active for the hydrosilylation of dodecene,decene,allyl phenyl ether,phenylpropene,chlorododecene,cyclohexene,acrylonifrile at 110℃.More than 75% of dodecene,decene,allyl phenyl ether,phenylpropene(10×10 -3 mol)were completely hydrosilylated with 23 2 mg complex containing 5×10 -6 mol platinum within 0 75h.The rate of hydrosilylation decreased with the decrease of temperature.The polymer complex can be easily recovered and reused.The structure of the platinum complex catalyst was studied by X ray photelectron spectroscopy(XPS).After having been stored under air for 0.5 year the catalyst was nearly as effective as the fresh one.
