Title
(DE) VERFAHREN ZUR HERSTELLUNG EINER HYDROXYVERBINDUNG DURCH DECARBOXYLIERUNG
(EN) METHOD FOR PRODUCTION OF A HYDROXY COMPOUND BY MEANS OF DECARBOXYLATION
(FR) PROCÉDÉ DE PRÉPARATION D'UN COMPOSÉ HYDROXY PAR DÉCARBOXYLATION
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung einer speziellen Hydroxyverbindung durch Decarboxylierung einer speziellen Carbonsäureverbindung oder eines Salzes dieser Carbonsäureverbindung, ein Verfahren zur Herstellung eines Diarylcarbonats, eines Bisphenols oder eines Polycarbonats, ein Diarylcarbonat oder Bisphenol, ein Polycarbonat und ein Verfahren zur Einstellung des Isotopenverhältnisses von C14 zu C12 in einem Polymer. Dabei wird eine spezielles Lösungsmittel während der Decarboxylierung verwendet.
