Abstract
Se rompe o se evita una mezcla azeotrópica de metanol/MMA con un método que comprende las etapas de (1) elevar la presión dentro de un primer recipiente, por ejemplo, una columna de destilación, que contiene una mezcla azeotrópica metanol/MMA, (2) recoger la mezcla azeotrópica como un líquido y luego en un segundo recipiente separado, por ejemplo, otra columna de destilación, (3) elevando la presión suficientemente para permitir la ruptura o la evitación de la mezcla azeotrópica y la recuperación del metanol.
