Abstract

La invención se refiere a un procedimiento para retirar especies de formaldehído de una corriente líquida de ácido carboxílico o de éster de ácido carboxílico que forma una mezcla bifásica con agua. Este procedimiento consiste en someter la mezcla orgánica líquida a al menos una etapa de extracción liquido/líquido. El agua se utiliza como agente de extracción para producir una corriente de fase orgánica prácticamente libre de formaldehído y una corriente de fase acuosa que contiene prácticamente la totalidad del formaldehído en las corrientes de salida de la extracción líquido/líquido. Este procedimiento es particularmente útil para reducir el contenido de formaldehído de una corriente de producto de metacrilato de metilo.
