Surface active agents — Technical straight-chain sodium alkylbenzenesulfonates — Determination of mean relative molecular mass by gas-liquid chromatography

Standard Details

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.
