Abstract

"MéTODO DE PRODUçãO DE ACETATO DE ETILA E EQUIPAMENTO PARA REALIZAR ESTE MéTODO". A invenção refere-se a um método de produção de acetato de etila reagindo-se o álcool de etila com ácido acético e/ou anidrido acético na presença de um catalisador acídico sólido e durante separação destilatória simultânea dos componentes de reação, no qual ácido acético ou anidrido acético ou sua mistura e álcool de etila são introduzidos separadamente na relação molar 2:1 para 1: 2,5 e em uma quantidade definida com base na unidade de volume do catalisador, no sistema separado em três zonas, por meio da qual, na zona de reação, a reação executa simultaneamente com a separação destilatória de componentes, a alimentação de ácido acético é introduzida na zona de reação ou acima da zona e alimentação de álcool de etila é introduzida na zona de reação ou abaixo desta zona, na zona de separação superior, a mistura volátil é separada, por conseguinte, é resfriada de 5 a 70<198>C e então separada da água e fases orgânicas e esta fase orgânica com conteúdo de acetato de etila elevado é retirada e parcialmente retornada como fluxo de refluxo neste sistema, por meio do qual, a relação da alimentação dos componentes consumidos e o fluxo de refluxo de fase orgânica é 1: 1 para 1:20. Uma matéria objeto desta invenção é também um equipamento para realizar este método.
