摘要
对二壬基萘碘酸钡添加剂有效组分的测定及表达方式进行了探讨，认为钡含量和灰分含量不能准确、直观地表达添加剂的有效组分含量，十六烷基溴化吡啶滴定法对具一定碱值的表面活性剂类添加剂也不适应。碱性二壬基萘磺酸钡有效组分应由钡含量和碱值共同确定。
The determination and representation of effective composition of dinonylnaphthalene sulfonate-barium anti - rust agent were discussed. It was thought that barium content and ash content can not representaccurately the effective comPOsition content of additives. The hexadecyl pyridine bromide titration method is unfit for surfactant with certain base number. The effective composition content depends on barium content andbase number.
