标准摘要
[中文适用范围]: 将测试部分与乙醇在硫酸钠存在下回流煮沸。 过滤溶液,蒸发滤液,并称重残余物。 通过将残余物溶解在丙酮水溶液中并用标准容量硝酸银溶液滴定来测定存在的任何氯化钠。 根据氯化钠含量校正残留物的质量。 [外文原描述]: A test portion is boiled under reflux with ethanol in the presence of sodium sulphate. The solution is filtrated, the filtrate evaporated, and the residue weighed. Any sodium chloride present is determined by dissolution of the residue in aqueous acetone and titration with a standard volumetric silver nitrate solution. The mass of the residue is corrected for the sodium chloride content.
英文名称Surface active agents — Sulfated ethoxylated alcohols and alkylphenols — Determination of total active matter content
