Abstract

Patente de Invenção: "PROCESSO E EQUIPAMENTO DE FABRICAçãO PARA A PREPARAçãO DE ACETAIS OU CETAIS". A presente invenção refere-se a um novo processo para a preparação de acetais e cetais. Como se sabe, os acetais e os cetais podem ser preparados por reação de um aldeido ou uma cetona com um álcool na presença de um catalisador catiónico. No entanto, a reação é reversível e, em temperatura ambiente ou acima, o equilibrio da reação é desviado para o lado dos materiais de partida, acetal ou cetona, e álcool. A invenção fornece um novo processo para a preparação contínua de acetais e cetais na forma concentrada e evita procedimentos de destilação de energia concentrada dos processos de fabricação convencionais, que freq³entemente tornam-se difíceis pela formação de azeótropos. A presente invenção refere-se ainda a um equipamento de fabricação para a realização do processo da invenção substancialmente como mostrado na figura 1 que compreende um reator (1) contendo um ácido sólido; um recipiente (2) que contém uma base sólida; e uma unidade de pervaporação (3) que tem uma membrana que é permeável para água.
