摘要
以咪唑催化邻苯二甲酸酐酰化的方法测定增强剂ＩＳ２１１的羟值，准确度高，分析误差为５０×１０－３；方法精密度好，标准偏差小于０４，变异系数不大于５０×１０－３，测定不同批号试样的羟值完全符合商标值，方法快速、简便，适用于常规分析。
An imidazole catalyzed acylation method of phthalic anhydride is applied to the determination of hydroxyl values of reinforcing agent IS211.The analytical error is 5.0×10 -3 .The relative standard deviation of the method is less than 0.04 and its coefficient of variation is not more than 5.0×10 -3 .Hydroxyl values determined in different batch samples meet the design requirement completely.This method is rapid and simple,it is adaptable to conventional analysis.
