Abstract
Improvements introduced in the object of the main patent No. 287,333, that is in a process for the preparation of carbohydric aromatic dicarboxylic acid esterases, with carboxyl groups in meta or para positions, especially of the iso- and terephthalic acids, by reaction of the methyl aryl esters of the carbocyclic aromatic dicarboxylic acids with ammonia or primary or secondary mono- or diamines, preferably in equivalent amounts, in indifferent organic solvents, preferably aromatic hydrocarbons, at temperatures from 0 to 150º C, especially between 60 and 100º C, characterized because, in place of the methyl aryl esters of said acids, the alkyl aryl esters are used for the reaction, the alkyl radical of which is derived from alkanoles having 2 to 5 saturated carbon atoms, straight or branched chain, and whose aryl moiety is derived from phenol and/or naphthol and/or phenols and/or naphthols substituted by u no or several alkyl and/or aralkyl groups.
