Abstract

<B>PROCESSO PARA A PRODUçãO DE ACETATO DE VINILA ATRAVéS DA REAçãO DE ETILENO, OXIGêNIO E áCIDO ACéTICO<D> é revelado um processo para a produção de acetato de vinila através da reação de etileno, oxigênio e ácido acético como reagentes, compreeendendo o contato dos referidos reagentes e de um composto de cobre não contendo halogênio com um catalisador que compreende um suporte poroso sobre superfícies porosas das quais são depositadas quantidades cataliticamente eficazes de paládio, ouro e cobre metálicos. Durante o processo para preparar acetato de vinila, uma corrente de acetato metálico alcalino é preferivelmente passada sobre o catalisador. O processo resulta em seletividade e produtividade mais elevadas de acetato de vinila, devido à menor seletividade de CO~ 2~ durante o tempo de vida do catalisador.
