Abstract

PROCESSO PARA ASEPARAçãO DE ACETALDEìDO DE IODETO DE METILA A PROCESSO PARA A PRODUçãO DE áCIDO ACéTICO é divulgado um método de controle de um processo de separação para remoção de compostos de redução de permanganato de uma corrente de processo no processo de carbonilação de metanol para fazer ácido acéico, onde o método inclui as etapas de medição da densidade de uma corrente contendo acetaldeíco e iodeto de metila, opcionalmente, calculando as concentrações relativas de acetaldeído e iodeto de metila na corrente e ajutando os parâmetro do precesso de destilação ou extração com base na densidade medida ou uma mais concentrações relativas calculadas da mesma.
