Analysis of sulfoxylated methyl esters (Φ-MES): Sulfonic acid composition and isomer identification

Abstract: Derivatization of a C 12 Φ-methyl ester sulfonic acid by using iodide-trifluoroacetic anhydride in dimethylformamide in a one-step reaction yielded derivatized sulfonic thiotrifluoroacetates. The latter have been analyzed by gas chromatography-mass spectrometry (MS) and liquid chromatography-MS techniques so that, for the first time, the acid composition and the mono sulfonic acid isomer distribution are shown.Paper no. S1298 in JSD 6, 151-154 (April 2003).KEY WORDS: C 12 Φ-sulfoxylated methyl ester, compositi… Show more

“…Both samples were subjected to a derivatisation process in order to turn sulphonated species (resulting from electrochemical reduction) into more volatile products. For his purpose, the sulphonic groups were chemically reduced to thiol groups using iodidetrifluoroacetic anhydride [65,66]. It was observed that both samples presented the characteristic peaks of derivatized 2-amine-1,5-naphthalenedisulphonic acid (figure not shown).…”

“…Two main conclusions were drawn: the palmitic acid U-MES (U-MES C16) could be used as an LAS partner in detergent formulations and the C16 alkyl chain was the optimal length. Since then, progress has been made concerning the development of a procedure for the separation of reaction products [4] and analysis [5,6]. These investigations have led to products with fewer impurities.…”

“…A method has been described to characterize the major anionic surfactant linear alkylbenzene sulfonate after derivatization by gas chromatography-mass spectrometry (GC-MS) (1). That method also has been applied to the analysis of sulfoxylated methyl esters (2). In this paper, the development of analytical methods to characterize surfactants is continued with the characterization of alcohol ethoxylates (AE).…”
