Olefin sulfonation method

摘要

A method for sulfonating olefins comprising the steps of mixing (A) internal olefins having 8 to 22 carbon atoms with (B) alpha-olefins having an average carbon atom number, larger by 3 to 7 than that of the internal olefins (A) in a weight ratio of (A)/(B)=95/5 to 5/95, and sulfonating the resultant mixture with a sulfonating agent. Thus, internal olefins can be sulfonated at a high conversion.
