A method of purifying It has been shown for the first time that Reaction paths for the oxidation free radical addition of thiolacetic acid to form thiolacetates, followed by hydrogen peroxide- acetic acid oxidation. reaction sequence permits the preparation of isomer-free terminal sulfonic acids from 1-olefins. 1-olefins by a partial, selective epoxidation procedure has also been described. methyl esters are obtained in high yield by reaction of sulfonic acids with ...
