Abstract
Procédé présentant un rendement amélioré. Il comprend la mise en contact, en présence d'un agent de dessiccation, d'un phénol, de monoxyde de carbone, d'une base, d'un élément du groupe VIII choisi parmi le ruthénium, le rhodium, le palladium, l'osmium, l'iridium ou le platine et un oxydant constitué par un élément, un composé ou un complexe ayant un potentiel d'oxydation supérieur à celui de l'élément du groupe VIII choisi. Application à la fabrication de polycarbonates.Process exhibiting improved yield. It comprises bringing into contact, in the presence of a drying agent, a phenol, carbon monoxide, a base, an element of group VIII chosen from ruthenium, rhodium, palladium, l osmium, iridium or platinum and an oxidant consisting of an element, a compound or a complex having an oxidation potential greater than that of the element of group VIII chosen. Application to the manufacture of polycarbonates.
