PRODUCTION METHOD FOR ALPHA-SULFOFATTY ACID ALKYL ESTER SALT, AND ALPHA-SULFOFATTY ACID ALKYL ESTER SALT

摘要

PROBLEM TO BE SOLVED: To provide anα-sulfofatty acid alkyl ester salt having a pale color close to white, and to provide a preferable method for stably performing a sulfonation reaction. SOLUTION: The production method for theα-sulfofatty acid alkyl ester salt includes a sulfonation process for sulfonating a fatty acid alkyl ester in which theα-sulfofatty acid alkyl ester is previously added thereto using a vessel-type sulfonation reaction apparatus, and is characterized in that a bubble-breaking blade 7 is installed above the level 3 of a reactant liquid 2 to perform sulfonation.
