Abstract

La presente invención se refiere a procedimiento para la preparación en continuo de carbonato dimetilo que comprende; caracterizándose por (a) la alimentación de metanol, óxido de carbono y oxígeno en un ambiente de reacción y conteniendo una mezcla líquida de metanol, carbonato dimetilo, agua y un catalizador de cobre; (b) la vaporización de la mezcla de reacción de una corriente de metano, agua y carbonato dimetilo, que se desarrolla junto a la corriente gaseosa que contiene óxido de carbono; y (c) la recuperación de esta mezcla hecha por vapor del agua y del carbonato dimetilo en una cantidad substancialmente igual a la formada en el ambiente de reacción y el reciclo de los otros componentes al lugar de reacción; el procedimiento queda caracterizado porque la composición y el volumen de la mezcla líquida de reacción se mantienen básicamente constantes en el tiempo, con una concentración de metanol igual o superior al 30 por ciento en peso y con una concentración de agua igual o inferior al 10 por ciento en peso en la mezcla misma.
