Abstract

um azeótropo de metanol/mma é quebrado ou evitada por um método compreendendo as etapas de (1) elevar a pressão dentro de um primeiro vaso, por exemplo, uma coluna de destilação, que contém um azeótropo de metanol/mma, (2) coletar o azeótropo como um líquido e, em seguida, em um segundo vaso, separado, por exemplo, uma outra coluna de destilação, (3) elevar a pressão suficientemente para permitir a quebra ou evitar a formação do azeótropo e a recuperação do metanol.
