| titleOfInvention | A PROCEDURE FOR THE ISOLATION OF METHYL ESTERS FROM DIPHENYLCARBOXYL ACIDS |
| abstract | A process for the isolation of methyl esters of diphenylcarboxylic acids from the distillation residues obtained in the manufacture of terephthalic acid dimethyl ester and/or isophthalic acid, residues which in themselves are not usable, characterized in that the residues of the distillation are first subjected to a subsequent esterification preferably with methanol, after which the residues obtained after the separation of the dimethyl esters of terephthalic acids are dissolved or digested in hot, in appropriate organic solvents. isophthalic, and the part soluble in the hot organic solvents is purified in the manner known per se, once said organic solvents have been separated, as well as the part insoluble in said hot organic solvents, optionally after being allowed to cool, to finally decompose it in the various methyl esters of dif acids enylcarboxylic.
