PROCESS FOR RECOVERING ALIPHATIC MONOCARBOXYLIC ACIDS FROM DISTILLATION RESIDUES
The present invention relates to a process for recovering aliphatic monocarboxylic acids having from 4 to 11 carbon atoms from the distillation residue obtained in the oxidation of the corresponding aldehyde by means of oxygen or oxygen-containing gas mixtures in the presence of alkali metal carboxy...

| description | The present invention relates to a process for recovering aliphatic monocarboxylic acids having from 4 to 11 carbon atoms from the distillation residue obtained in the oxidation of the corresponding aldehyde by means of oxygen or oxygen-containing gas mixtures in the presence of alkali metal carboxylates or alkaline earth metal carboxylates to form the corresponding monocarboxylic acid and subsequent distillation, wherein the distillation residue is reacted with an aqueous acid in a tube reactor.
La presente invención se refiere a un proceso para recuperación de ácidos monocarboxílicos alifáticos que tienen de 4 a 11 átomos de carbono a partir del residuo de destilación obtenido en la oxidación del aldehído correspondiente por medio de oxígeno o mezclas de gas que contienen oxígeno en presencia de carboxilatos de metal alcalino o carboxilatos de metal alcalinotérreo para formar el ácido monocarboxílico correspondiente y destilación subsecuente, en donde el residuo de destilación se hace reaccionar con un ácido acuoso en un reactor del tubo. |
