一、引言在合成具有各种特殊性能的有机硅高聚物中,作为中间体的硅氯仿愈来愈引起人们的兴趣,因为在硅氯仿(HSiCl_3)分子中含有一个活泼氢;能和其他合物发生各种反应,并得到很多重要单体,例如: CH≡CH+HSiCl_3→CH_2=CHSiCl_3………………………(1) CH_2=CH_2+HSiCl_3→CH_3CH_2SiCl_3…………………(2) Cl_2C=CHCl+HSiCl_3→ClHC=CClSiCl_3+HCl…………(3) RMgX+HSiCl_3→RSiHCl_3+Mg X Cl………………………(4)由反应(1)、(3)及(4)式所得到的单体合成高聚物后,在高分子中含有不饱和的侧链、极性原子,以及硅氢键,它们将引起高聚物性能的极大改变;由反应式(2)也可看出扩大了合成乙基单体的原料来源。 1934年StillWell曾在以前很多研究工作的基础上用氯化氢(HCl)通入硅铜合金
I. INTRODUCTION In the synthesis of silicone polymers with various special properties, as an intermediate of silicon chloroform more and more attracted people’s interest, because in the silicon chloroform (HSiCl_3) molecule contains an active hydrogen; and other combinations Various reactions take place and many important monomers are obtained, for example: CH≡CH + HSiCl_3 → CH_2 = CHSiCl_3 ........................... (1) CH_2 = CH_2 + HSiCl_3 → CH_3CH_2SiCl_3 (2) Cl_2C = CHCl + HSiCl_3 → ClHC = CClSiCl_3 + HCl (3) RMgX + HSiCl_3 → RSiHCl_3 + Mg X Cl (4) ) And (4) obtained after the synthesis of the polymer monomer, the polymer contains unsaturated side chains, polar atoms, and silicon hydrogen bonds, they will cause a great performance changes of polymers; from Reaction (2) can also be seen to expand the source of raw materials for the synthesis of ethyl monomers. 1934 StillWell had many previous studies based on the use of hydrogen chloride (HCl) access silicon copper alloy
