Abstract

Patente de Invenção: <B>"PROCESSO PARA A PRODUçãO DE áCIDO TEREFTáLICO E/OU TEREFTALATO DE DIMETILA"<D>. Um processo para a produção de ácido tereftálico e/ou tereftalato de dimetila inclui o contato de uma corrente de reação contendo tolueno com um primeiro catalisador sob condições de desproporção de tolueno para produzir uma corrente de produto intermediário de para-xileno com ortoxileno insignificante. O primeiro catalisador inclui uma peneira molecular cristalina que tem uma taxa de difusão de orto-xileno de pelo menos 50 minutos. O primeiro catalisador pode ser modificado através de seleção com um composto silício ou composto carbono. A corrente de produto intermediário, sem necessidade de purificação do para-xileno, é oxidada para ácido tereftálico de dimetila.
