标准范围

试验部分在浓磷酸介质中脱硫，释放的烷基苯用轻质石油萃取。用色谱法测定萃取烷基苯的平均相对分子质量。计算了烷基苯磺酸钠的平均相对分子质量。

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.
