Abstract
Patente de Invenção:<B>"PROCESSO PARA A PRODUçãO DE CARBONATOS AROMáTICOS"<D>. O processo melhorado da presente invenção compreende a reação de um composto de hidróxi aromático, monóxido de carbono e oxigênio na presença de um sistema catalisador que compreende um composto de paládio, um co-catalisador inorgânico e uma fonte de halogeneto, em que a redução do consumo de fonte de halogeneto é efetuada pela adição de material co-catalisador inorgânico à mistura de reação inicial.Invention Patent: <B> "PROCESS FOR THE PRODUCTION OF AROMATIC CARBONATES" <D>. The improved process of the present invention comprises the 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, in which the reduction of the consumption of the halide source is effected by adding inorganic co-catalyst material to the initial reaction mixture.
