Abstract

Se separan continuamente mezclas de líquidos, que contienen el ácido (met) acrílico como el componente principal, en un aparato de destilacion, el cual comprende un destilador, un condensador y una conexion entre el destilador y el condensador y al cual se alimenta continuamente la mezcla de líquidos que se va a separar mediante un procedimiento, en el cual la energía requerida para la evaporacion de la mezcla de líquidos se suministra al aparato de destilacion mediante un procedimiento en el cual una parte del líquido contenido en el destilador se remueve continuamente, se sobrecalienta y se recicla a este destilador.
