โœฆ Synopsis

Hydrolysis reactions of methyl, ethyl, isopropyl, and t-butyl benzenesulfinates were kinetically investigated. Rates of alkaline hydrolysis decrease with increasing steric effects (Me > Et > i-Pr > t-Bu), while the t-butyl ester is the most reactive in perchloric acid (t-Bu > Me > E t => i-Fr). The hydrolysis is faster in

HCl and HBr than in HC1O4, and the relative rates in the halide acids are not unusual (Me > Et > i-Pr t-Bu). The high reactivity of the t-butyl ester in HCIO, is ascribed to the reaction at the carbon via the A1 mechanism, while halide ions accelerate the hydrolysis by nucleophilic participation at sulfur.

## Abstract **BACKGROUND:** The hydrolysis of methyl formate is the major industrial process for the production of formic acid. The aim of the work is to determine the reaction kinetics quantitatively in the presence of formic acid catalyst, develop a mathematical model for the reaction system and
