Plastics — Polyols for use in the production of polyurethanes — Determination of degree of unsaturation by using iodine method 塑料聚氨酯生产用多元醇碘法测定不饱和度

发布日期： 2024-09-16

作为测定聚氨酯用聚醚多元醇的总不饱和度的方法，该文献规定了使用卤素间化合物一氯化碘(ICl)的加成反应、使用冰醋酸作为溶剂来定量总不饱和度的方法。它不适用于与羰基、羧基或腈基共轭的不饱和化合物。

This document specifies a method for quantifying the total unsaturation using an addition reaction of the interhalogen compound iodine monochloride (ICl), using glacial acetic acid as a solvent as a method for measuring the total unsaturation of a polyether polyol for polyurethanes. It is not applicable to unsaturated compounds that are conjugated with a carbonyl group, a carboxyl group, or a nitrile group.
