Abstract Saturated and unsaturated 1,3‐ and saturated 1,4‐sultones in anionic surfactants are identified and measured by a series of separation maneuvers. The sultones are separated from the surfactant by ion‐exchange treatment and concentrated by thin layer chromatography. By the use of high performance liquid chromatography, the sultones are identified on the basis of their retention times and are measured by comparing their peak areas with those of reference compounds. Adequate responses are obtained from 5 μg quantities of sultone, corresponding to 0.1 ppm sultone in a 50 g sample of alkylethoxy sulfate paste. All the sultones of interest are separated from each other. Chlorosultones can be determined after first treating them with collidine, which dehydrohalogenates them to the unsaturated sultones.
