Abstract

Patente de Invenção: <B>"CATALISADOR, PROCESSO PARA A PREPARAçãO DO CATALISADOR E PROCESSO PARA A PREPARAçãO DE ACETATO DE VINILA SOB APLICAçãO DO CATALISADOR"<D>. O presente processo possibilita a preparação de um catalisador para a produção de acetato de vinila na fase de gás, a partir de etileno, de ácido acético e de oxigênio ou de gases contendo oxigênio, que contêm paládio e/ou seus compostos, ouro e/ou seus compostos, bem como compostos de metais alcalinos sobre um suporte poroso, em forma de partículas, sendo que o catalisador é preparado, a) impregnando-se o suporte com compostos de paládio e de ouro solúveis, b) convertendo-se os compostos de paládio e de ouro solúveis, por adição de uma solução que reage alcalinamente, sobre o suporte, em compostos de paládio e de ouro insolúveis, c) reduzindo-se os compostos de paládio e de ouro insolúveis, sobre o suporte, por um agente de redução em fase líquida ou gasosa, d) impregnando-se o suporte com pelo menos um composto de metal alcalino solúvel e e) secando-se o suporte, finalmente, em, no máximo, 150°C, sendo que o catalisador, no âmbito da etapa b), é colocado em contato com pelo menos um composto peroxídico.
