Abstract
This article introduces a convenient preparation of 4\|(methylsulfonyl)benzoic acid from 4\|methylbenzenesulfonyl chloride. Through reduction, methylation, oxidation, and purification, the purity of the product can reach over 98%, and the total yield can reach 51.8%. This technology greatly reduces the cost, particularly the employing of chloroacetic acid instead of dimethyl sulfate in the methylation process makes considerable contributions to environment protection. So it is suitable for large\|scale production.
