摘要

PURPOSE: To purify a recovered solvent which is used in the production of α-sulfo-fatty acid alkyl ester salt by treating it with specific substances, by which the oxidative substances included in the solvent are decomposed and deodorized and the quality of the product can be improved, when the solvent is reused. ;CONSTITUTION: A solvent, which is used in the production of an α-sulfo-fatty acid alkyl ester salt, is treated with (A) a reductive substance such as sodium (hydrogen) sulfite or sodium thiosulfate or (B) an alkaline substance such as sodium hydroxide, potassium hydroxide, calcium hydroxide, sodium carbonate or potassium carbonate and rectified to obtain the purified solvent. The amounts of the components A and B are 0.05-2wt.% and 0.02-10wt.% based on the recovered solvent.;COPYRIGHT: (C)1996,JPO
