Oxidation of p-methyl Benzaldehyde to p-methylbenzoic Acid by H2O2
摘要
Abstract
[Objective] The aim was to explore oxidation conditions of p-methyl benzaldehyde to p-methylbenzoic acid by H2O2. [Method] Using hydrogen peroxide as an oxidant catalyze, p-methyl benzaldehyde was oxidized into p-methylbenzoic acid under the alkaline condition, and the operation conditions were optimized by orthogonal test. The product was determined by melting point and infrared spectrometry. [ Result ] The optimal operation conditions were as followed: the molar ratio of p-methyl benzaldehyde and 30% H2 O2 was 1:6; the reaction temperature was 40 ℃ ; and the concentration of KOH was 60%. Under the best reaction conditions, the yield of p-methylbenzoic acid reached more than 91% , and the reproducibility experiment result showed that the average yield of p-methylbenzoic acid reached 91.7%. [Conclusion ] The research lays a foundation for the industrial production of p-methylbenzoic acid.关键词
