Title (EN) PROCESS FOR ALDEHYDE REMOVAL FROM ALCOHOLS BY TREATMENT WITH BISULPHITE
(FR) PROCÉDÉ D'ÉLIMINATION D'ALDÉHYDE À PARTIR D'ALCOOLS PAR TRAITEMENT AU BISULFITE
Abstract:
(EN) A method of purifying alcohol produced in a process that includes the Oxo process is disclosed. Aldehyde from the Oxo process that remains with the alcohol is removed by a reaction with an alkali sulphite to produce an insoluble adduct and alcohol having a reduced amount of aldehyde mixed with it. The adduct is removed from the alcohol by filtration.
(FR) L'invention concerne un procédé de purification d'alcool produit dans un procédé comprenant un procédé oxo. L'aldéhyde provenant du procédé oxo qui reste avec l'alcool est éliminé par une réaction avec un sulfite alcalin afin de produire un produit d'addition insoluble et un alcool ayant une quantité réduite d'aldéhyde mélangé avec celui-ci. Le produit d'addition est retiré de l'alcool par filtration.
