标准摘要
[中文适用范围]： 本文件规定了一种使用加成反应将中分子碘化物单质加到聚醚多元醇上以测量其总不饱和度的方法。 本文件不适用于与羰基、羧酸或氰基共轭的不饱和化合物 [外文原描述]： 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.
英文名称Plastics — Polyols for use in the production of polyurethanes — Determination of degree of unsaturation by using iodine method
