BS 6829-3.1:1989
This standard BS 6829-3.1:1989 Analysis of surface active agents (raw materials). Sodium alkylbenzenesulphonates is classified in these ICS categories:
- 71.100.40 Surface active agents
This International Standard specifies a gas-liquid chromatography (GLC) method for the determination of the mean relative molecular mass of technical straight-chain sodium alkylbenzenesulfonates.
Desulphonation in phosphoric acid, extraction with light petroleum and determination by gas-liquid chromatography. Applicable only to straight-chain sodium alkylbenzenesulphonates.
