A New Gas Chromatographic Analysis of Alkyl Benzenesulfonate

Determination of alkyl chain distribution of alkylbenzenesulfonates by liquid chromatography

“…This method, however, requires the conversion of LAS into the volatile derivatives before analysis. Desulfonation with acids (1-4), alkali fusion (5), sulfochlorination (6), methylation (7), reduction to the alkylthiophenol (8), pyrolysis-GC (9), and "acid" pyrolysis-GC (10,11) have been well-known methods of prederivatization for the GC determination.…”

Determination of linear alkylbenzenesulfonates and dialkyltetralinsulfonates in water and sediment by gas chromatography/mass spectrometry

“…LAS can also be determined after conversion to either sulfonyl chlorides (26)(27)(28)(29) or methyl sulfonates (30,31). Methyl sulfonate derivatives of alkylbenzenesulfonates have been prepared by reaction with diazomethane (32) and by conversion of the sulfonyl chloride to methyl sulfonates in a two-step procedure (31).…”

Determination of linear alkylbenzenesulfonates in sewage sludge by high-resolution gas chromatography/mass spectrometry

“…The advantage of HRGC and in particular of HRGC/MS is that complex mixtures can be resolved into individual components. Frequently, LAS are recovered from methylene blue complexation on an ion-exchange column and then prepared for GC by either desulfonation to give alkylbenzenes (17)(18)(19) or derivatization to sulfonyl chlorides (20)(21)(22) or sulfonate esters (20,23,24).…”
