摘要

本文探讨了染料-纤维化合物及模拟染料-纤准化合物的减性水解动力学.测定了它们的水解反应速度常数.认为模拟化合物可以较好地反映出真实化合物的水解情形.运用分子轨道函数(MolecularOrbital)理论(简称:M.O理论)

计算并讨论了包括模拟化合物在内的二十个三嗪、嘧啶类化合物碱性水解反应速度的大小及反应途径.由计算得到的反应性指数“超高域度”较好地反映了实验情况.

Abstract

A series of dye-cellulose compounds and their corresponding models were synthesized. The alkali-hydrolysis rate constants of these compounds were measured

and the kinetics and mechanism of the hydrolysis were investigated. The molecular orbital theory was used in analyzing the hydrolytic behavior of twenty compounds including their models. It was found that the hydrolytic behavior of any dye-cellulose might be well approximated by its corresponding model. Fukis superdelocalizability SrN is a good reaction index for correlating the hydrolysis reaction.
