摘要: 应用热动力学法研究了N,N,N',N'-四甲基-1,3-丙二胺与溴代正丁烷之间的连续季铵化反应,测定了25.0、35.0及45.0℃下DMF和DMSO溶剂中该反应的速率常数,计算得到了其活化能及活化自由能,并讨论了温度和溶剂对反应动力学的影响。这些结果对认识季铵盐型离子聚合物的形成机理及反应条件的选择是十分重要的。

Abstract: The consecutive quaternization between N, N, N', N'-tetramethyl-1, 3-propylenediamine and bromobutane in DMFand DMSOat 25.0℃, 35. 0℃ and 45.℃was studies with thermokinetic method. Rate constants of two steps were calculated, and activation energies and activation free-energies were obtained. The influences of temperature and solvent on the reaction kinetics have been discussed, which is considered to be important for the elucidation of the formation mechnism and the choice of synthetic conditions of ionene polymers.
