PROCESS FOR REDUCTIVE CARBONYLATION OF ALDEHYDES THROUGH HEMIACETAL-ESTERS, CATALYZED BY THE CARBONYL COMPLEXES OF COBALT

摘要

The invention relates to a process for reducing carbonization of an aldehyde in which the aldehyde is used in the form of hemiacal-ester, the reaction being carried out in the presence of a catalyst which is a carbonate complex of Cobalt. / P P HEMIACETAL-ESTER CAN BE OBTAINED IN SITU BY REACTING ACETAL AND ACID ANHYDRIDE. / P P THE PROCESS PREFERENTIALLY OBTAINES FREE OR ESTERIFIED ALKYLENE GLYCOL MONOETHERS FOR HCO RATIO BETWEEN 1: 1 AND 3: 1, AND PREFERENTIALLY ALKOXY-2 ALDEHYDES FOR AN HCO RATIO BETWEEN 0.1: 1 AND 0.5: 1. / P
