本标准首次发布于1989年,本次为第一次修订。本标准代替GB/T11989—1989《阴离子表面活性剂 石油醚溶解物含量的测定》。本标准规定了阴离子表面活性剂中石油醚溶解物含量的测定方法。本标准适用于液体、浆状和粉状烷基苯磺酸盐、烷基磺酸盐、烷基硫酸盐中石油醚溶解物含量的测定。 本标准与GB/T11989—1989的主要变化如下:
———明确了本标准系修改采用了国际标准ISO894:1977中的部分内容;
———增加了一项引用标准,即GB/T8447—1995 《工业直链烷基苯磺酸》;
———增加采用具塞量筒及虹吸管进行萃取操作的方法。
Scope
This standard specifies the determination method for the content of petroleum ether solubles in anionic surfactants. This standard applies to the determination of petroleum ether solubles in liquid, slurry and powder alkylbenzene sulfonates, alkyl sulfonates and alkyl sulfates.
