摘要

本工作合成了脲醛树脂模型化合物亚甲基二脲、Uron和5-乙基-2（1）-s-四氢三嗪酮,并测定了它们在pH=4和80℃温度下的水解率。这三个模型化合物在酸性介质中的稳定性为:Uron>亚甲基二脲>5-乙基-2（1）-s-四氢三嗪酮。

Abstract

In this study, three model compounds of urea-formaldehyde resin, such as methylene diurea, Uron and tetrahydro-5-ethyl-2(1)-s-triazone, were synthesized. The rate of hydrolysis in pH 4.0 buffer solution at 80℃ was measured with iodimetric method. The result showed that the stability orderof the model compounds in acid condition was Uron>methyene diurea>tetrahydro-5-ethyl-2(1)-s-triazone.
