Abstract

The working conditions of synthesizing 2_methylbutanoic acid by oxidizing 2_methyl_1_butanol with tetrabutylammonium hydrosulfate(TBAS) or tetrabutylammonium perchlorate(TBAP) as phase transfer catalyst in sulfuric acid Cr(Ⅵ) oxidation medium was studied. The Cr(Ⅵ) oxidation medium could be electrolytic regenerated from Cr(Ⅲ), during above oxidation reaction.Under the optinum condition,the yield of 2_methylbutanoic acid is more than 95%.
