What is the mechanism of lactone hydrolysis?
Mechanism: Lactones are cyclic esters and readily and irreversibly hydrolyze in alkaline media to produce a hydroxycarboxylate. Although carboxylic acids are weak acids they are completely ionized in basic media.What is the mechanism of alkaline hydrolysis reaction?
The mechanism of alkaline hydrolysis is believed to be saponification of intermolecular ester bonds cross-linking xylan hemicelluloses and other components, for example, lignin and other hemicelluloses.What is the mechanism of lactone formation?
Lactones are cyclic organic esters of hydroxycarboxylic acids, usually formed by the reaction of a halogen atom or hydroxyl group with a carboxylic acid group present in the same molecule. These are formed by intramolecular esterification of respective hydroxycarboxylic acids.- Alkaline hydrolysis of nitriles generally results in the formation of the salt of the carboxylic acid and ammonia, and is conveniently applied to the simple alkyl cyanides and also to nitriles such as ?-cyanocarboxylic acids producing dicarboxylic acids which are unstable in hot mineral acid.
