Statement-1:Acid catalysed hydrolysis of ester is reversible while base catalysed hydrolysis is irriversible . Statement-2: In acid catalysed ester hydrolysis carboxylic acid is formed on which nucleophilic attack of alcohol is possible but in base catalysed ester hydrolysis carboxylate anion is formed...
product, the process includes the steps of introducing into a reaction zone of a reactive distillation column a feed containing the alkyl ester wherein the reaction zone is at a temperature and pressure to preferentially produce an ether from the ester; and recovering the ether and the carboxylic...

When longer alkyl ester such as butyl acetate is hydrolysed with partially sulfonated polystyrenes, the ester molecules are bound by hydrophobic interaction between a benzene ring and the alkyl group to result in a higher concentration of ester in the neighborhood of polymer molecule. In such a ...
Mild, selective, and efficient: A new method that involves the use of trimethyltin hydroxide for the hydrolysis of specific ester groups allows chemists to steer clear of unwanted elimination reactions and epimerizations. For example, the conversion of ester 1 into carboxylic acid 2 takes place und...
