摘要
探讨了用电导法跟踪高反应活性的五配位硅钾化合物与2-氯乙醇反应制备双羟基四配位硅化合物的动力学行为,从而确定该反应的反应级数为二级反应,得出在甲醇体系中反应的速率常=1.233h、t53℃=数k64℃=1.818(mol/dm3)-1·h-1、k53℃=0.4437(mol/dm3)-1·h-1,半衰期t64℃11225.051h,和该反应的活化能Ea=86.987kJ/mol。
The chemical kinetics of synthesizing di-hydroxyl tetra coordinated silicon from a highly, reactive pentacoordinated silicon with ClCH_2CH_2OH was studied by electric conductance method. This reaction was a second order reaction. The rate constants of reaction k_(64℃)=1.818(mol/dm^3)^(-1)·h^(-1)、k_(53℃)=0.4437(mol/dm^3)^(-1)·h^(-1)、half lifs t~^(64℃)__(12)=1.233 h, t~^(53℃)__(12)=5.051 h and activation energy E_a=86.987 kJ/mol were determined.
