Benzonitrile is converted to benzoic acid by basic hydrolysis. When benzonitrile is heated with aqueous sodium hydroxide solution, it liberates ammonia gas and converts to sodium benzoate which on acidification gives benzoic acid.

Table of the experimental kinetic data for runs 1−15. You’ve supercharged your research process with ACS and Mendeley! The hydrolysis of benzoic anhydride enjoys two mechanisms of acid catalysis in 60%(v/v) dioxane–water as solvent, one at low and another at high values of [H 3 O + ]; the former becomes effectively undetectable in a purely aqueous solvent. The LHHW model yielded the best representation for the kinetic behavior of the liquid−solid catalytic synthesis and hydrolysis of ethyl benzoate. These metrics are regularly updated to reflect usage leading up to the last few days. The esterification of benzoic acid with ethanol was implemented at temperatures between 323.15 and 353.15 K under various molar ratios of feed, θB0 (ethanol to benzoic acid).
