${alpha}-sulfonated$ fatty acid polyethylene glycol esters with polyethylene oxide(addition, 3, 5, 10mol) were synthesized through esterification of ${alpha}-sulfonated$ fatty acid methyl esters with alkyl chain length $C_{12}{sim}C_{18}$. Their compounds were separated with column chromatography, and confirmed by TLC. Quantitative analysis of all the sulfonates were performed according to JIS K-3362 method, and ethylene oxide unit number were determined by ISO 2270 method. Structural properties of ${alpha}-sulfonated$ fatty acid methyl esters and their derivatives were also identified from IR, and $^1H$ NMR spectra.
