Abstract

patente de invenção: "purificação de ácido acético". a presente invenção refere-se a um método para remoção de impurezas de aldeído de uma corrente de ácido acético. o método compreende a reação de impurezas de aldeído com um composto hidroxila em uma coluna de destilação a seco ou em uma coluna combinada para formar acetais correspondentes. os acetais são subsequentemente removidos como impurezas pesadas de ácido acético por destilação.
