聚氨酯用羟基化合物羟值的分析

Analysis on use of the hydroxyl compound in polyurethane

综述了聚氨酯用羟基化合物羟值的分析方法,并对各种方法进行了分析比较。基于醇羟基和酚羟基化合物的特殊性,分析方法有类似又有区别,实际工作中要区别对待。

Summarized the analysis method of hydroxyl value of polyurethane in this article, and the comparisons of these methods are also carried out. Because the particularity of hydroxyl and the phenol hydroxyl compound, the analysis method is similarly as well as difference, it proposes the analysis on hydroxyl value should make a difference between hydroxyl and the phenol hydroxyl compound in practical work.
