Abstract

a presente invenção refere-se a um processo de purificação de uma solução aquosa que compreende etanol, acetaldeído e dietilacetal que compreende: - uma etapa a) de extração líquido-líquido em contracorrente que compreende uma seção de extração alimentada no topo pela dita solução aquosa em mistura com pelo menos uma fração do refinado água/etanol/acetaldeído proveniente da etapa b) de re-extração, e no fundo por um solvente de extração, e que produz no topo um extrato e no fundo uma carga purificada; - uma etapa b) de re-extração líquido-líquido em contracorrente que compreende uma seção de re-extração alimentada no topo por uma solução aquosa ácida da qual o ph é compreendido entre 0,5 e 5, e no fundo pelo extrato proveniente da etapa a), e que produz no topo um extrato e no fundo um refinado água/etanol/acetaldeído.
