Abstract

Patente de Invenção: <B>"CATALISADORES DE SUPORTE CONTENDO METAL DO GRUPO PLATINA E PROCESSO PARA A PREPARAçãO DE CARBONATOS DE DIARILA"<D>. A presente invenção refere-se a catalisadores de suporte contendo metais do grupo platina, cujos suportes contêm óxidos mistos de metais, metais de transição e elementos semicondutores, os quais, sob condições reacionais podem agir como catalisadores de oxi-redução e que foram produzidos em um processo sol-gel, bem como o emprego de catalisadores de suporte no processo para a preparação de carbonatos de diarila através da reação de compostos aromáticos de hidroxila com monóxido de carbono e oxigênio.
