Effect of Varying Acetic Acid Concentration on the Reaction Rate between Aromatic Aldehydes and Tertiary Butyl Hypochlorite

Abstract

Venu Sangal *

In this paper the influence of solvent dielectric constant on the rate of oxidation of p-methoxybenzaldehyde and pmethylbenzaldehyde with t-BuOCl has been studied in various solvent mixtures of acetic acid and water. The results indicate that in the oxidation of p-methoxybenzaldehyde with t-BuOCl the rate increases with increase in the percentage of acetic acid (from 10% to 40%), but the rate decreases with further increace in acetic acid content (50-80% HOAc). In the oxidation of p-methylbenzaldehyde with t- BuOCl the rate is maximum at 50% HOAc and decreases on either side of this percentage.
