Title (EN) PROCESS FOR PRODUCTION OF CARBOXYLATED PHENOL DERIVATIVES
(FR) PROCÉDÉ DE PRODUCTION DE DÉRIVÉS DE PHÉNOL CARBOXYLÉS
Abstract:
(EN) Disclosed is a new process for the production of carboxylated phenol derivatives comprising at least a step of carboxylation of a mixture of (i) phenol derivative and (ii) phenolate derivative, wherein the molar ratio of (i) / (ii) is comprised between 0.8 and 1.2, in presence of CO2. A process for the production of said mixture of (i) phenol derivative and (ii) phenolate derivative is also disclosed.
(FR) L'invention concerne un nouveau procédé de production de dérivés de phénol carboxylés comprenant au moins une étape de carboxylation d'un mélange (i) de dérivé de phénol et (ii) de phénolate, le rapport molaire de (i)/(ii) étant compris entre 0,8 et 1,2 en présence de CO2. L'invention concerne également un procédé de production dudit mélange de (i) dérivé de phénol et de (ii) dérivé de phénolate.
