摘要
介绍了用电位滴定法测定抗氧抗腐剂二烷基二硫代磷酸锌 (简称ZDDP)中碱性盐的含量。考察了方法的准确性 ,实验证明该方法简单易行 ,而且对中性盐与碱性盐有良好的区分性 。
Basic zinc salt content in zinc dithiophosphates(ZDDP)was deterimined by potentiometric titration with its precision proved.Experiment results showed that it was a easy way and had good differentiation between neutral ZDDP and basic ZDDP.It was applicable to control the product quality and technological parameters.
