In the production of detergent range olefin sulfonates a rapid and relatively simple method for the analysis of compounds produced is desirable. This paper describes a thin layer chromatographic technique for the separation and quantitation of the sodium salts of alkene monosulfonates and disulfonates and hydroxy alkane monosulfonates and disulfonates. The separation is accomplished on tracked, unactivated sulfate‐impregnated Silica Gel G layers. Standard equilibrated developing tank conditions are employed in conjunction with a developing solvent of chloroform‐methanol‐sulfuric acid. Visualization of the compounds is based on their suitability for charring by heat and SO 3 fumes resulting from fuming sulfuric acid which is smeared on the inner sandblasted surface of a charring lid. The charred compounds are quantitated using a scanning photodensitometer. Areas of resultant peaks are calculated and related to composition of the sample.
