摘要
The invention relates to a method of carbonylation reductive of an aldehyde, in which the aldehyde is used in the form of hemiacetal - ester, the reaction being effected in the presence of a catalyst which is a complex of the cobalt carbonyl. / p & & p & the hemiacetal - ester may be obtained in situ by reaction of an acetal and an acid anhydride. / p & & p & the method makes it possible to obtain, preferably of monoethers of glycol, alkylene - free or esterified for an hco between 1: 1 and 3: 1, and preferably of the alkoxy - 2 aldehydes, for an hco between 0,1: 1 and 0,5: 1).
