Process for producing clear aqueous solution of olefin sulfonic acid |
摘要 |
Disclosed is a process for producing a clear aqueous solution of the magnesium salt of an olefin sulfonic acid by (i) sulfonating an olefin with an gaseous sulfur trioxide, (ii) neutralizing the resulting sulfonated olefin with an inorganic alkali consisting of magnesium hydroxide and/or oxide and an organic amine selected from water-soluble alkanol amines in specified amounts and, then, (iii) heating the neutralized mixture at a pH of from 6.0 to 8.0. Thus, a clear aqueous solution of the magnesium salt of an olefin sulfonic acid having no bad odor and no color deterioration can be obtained.
