Abstract
The disclosed methods for preparing and isolating carboxylic esters ensure a high product purity and minimize technical complexity. These methods are based on the reaction of a carboxylic acid with an alcohol in an aqueous medium. In some examples, the alcohol is used both for the esterification and for the precipitation of the salts, preferably ammonium salts, formed in the synthesis.
