Title
(DE) VERFAHREN ZUR HERSTELLUNG EINER HYDROXYVERBINDUNG DURCH DECARBOXYLIERUNG IN ANWESENHEIT EINER BRÖNSTED-BASE
(EN) METHOD FOR PRODUCING A HYDROXY COMPOUND BY DECARBOXYLATION IN THE PRESENCE OF A BRONSTED BASE
(FR) PROCÉDÉ DE PRODUCTION D'UN COMPOSÉ HYDROXY PAR DÉCARBOXYLATION EN L'ABSENCE D'UNE BASE DE BRONSTED
Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer speziellen Hydroxyverbindung durch Decarboxylierung einer speziellen Carbonsäureverbindung oder eines Salzes dieser Carbonsäureverbindung in Anwesenheit einer Brönsted-Base, ein Verfahren zur Herstellung eines Diarylcarbonats oder eines Bisphenols, ein Verfahren zur Herstellung eines Polycarbonats und eine Verwendung einer Brönsted-Base bei der Reaktion der Decarboxylierung einer speziellen Carbonsäureverbindung oder eines Salzes dieser Carbonsäureverbindung.
(EN)
The invention relates to a method for producing a specific hydroxy compound by decarboxylating a specific carboxylic acid compound or a salt of said carboxylic acid compound in the presence of a Bronsted base. The invention also relates to a method for producing a diaryl carbonate or a bisphenol, to a method for producing a polycarbonate and to a use of a Bronsted base during the reaction of the decarboxylation of a specific carboxylic acid compound or a salt of said carboxylic acid compound.
(FR)
L'invention concerne un procédé de production d'un composé hydroxy particulier, par décarboxylation d'un composé acide carboxylique particulier ou d'un sel de ce dernier en présence d'une base de Bronsted, un procédé de production d'un carbonate de diaryle ou d'un bisphénol, un procédé de production d'un polycarbonate et une utilisation d'une base de Bronsted lors de la réaction de décarboxylation d'un composé acide carboxylique particulier ou d'un sel de ce dernier.
