标准摘要
[中文适用范围]： 将测试部分在浓磷酸介质中脱磺化，并用轻质石油萃取释放的烷基苯。 通过色谱法测定萃取的烷基苯的平均相对分子质量。 计算烷基苯磺酸盐的平均相对分子质量。 [外文原描述]： A test portion is desulfonated in concentrated phosphoric acid medium and the liberated alkylbenzene is extracted with light petroleum. The mean relative molecular mass of the extracted alkylbenzene is determined chromatograhically. The mean relative molecular mass of the alkylbenzenesulfonate is calculated.
