Title
(EN) PROCESS FOR THE PRODUCTION OF AROMATIC CARBONATES
(FR) PROCEDE DE PRODUCTION DE CARBONATES AROMATIQUES
Abstract
(EN)
The improved method of the present invention comprises reaction of an aromatic hydroxy compound, carbon monoxide, and oxygen in the presence of a catalyst system comprising a palladium compound, an inorganic co-catalyst, and a halide source, where the reduction of consumption of the halide source is effected by the addition of inorganic co-catalyst material to the initial reaction mixture.
(FR)
L'invention concerne un procédé amélioré, comprenant la réaction d'un composé hydroxy aromatique, de monoxide de carbone, et d'oxygène, en présence d'un système catalyseur comprenant un composé palladium, un cocatalyseur minéral, et une source d'halogénure, réaction dans laquelle on réduit la consommation de la source d'halogénure par addition d'un cocatalyseur minéral au mélange réactionnel initial.
