Abstract

Patente de Invenção: <B>"REMOçãO DE CHUMBO DE MISTURAS DE REAçãO ORGâNICAS DE CARBONATO DE DIARILA"<D>. A presente invenção refere-se a método para a remoção eficiente de espécies de co-catalisadores de chumbo de correntes orgânicas de processo que se originam da síntese de carbonatos de diarila, através do contato das misturas de reação orgânicas com uma solução aquosa de ácido, sal e/ou ácido/sal, dessa forma, extraindo a mistura tratada em uma fase aquosa ou através de tratamento das misturas de reação orgânicas com um ácido oxálico sólido ou sal de ácido oxálico sólido ou uma solução aquosa de ácido oxálico ou sal de ácido oxálico, dessa forma, resultando na precipitação de chumbo. O chumbo precipitado pode, então, ser calcinado a fim de proporcionar um composto de chumbo que é cataliticamente ativo na carbonilação de fenol a fim de proporcionar carbonatos de diarila. O uso desses métodos reduzirá substancialmente as preocupações financeiras e ambientais quanto ao preparo de carbonatos de diarila.
