Abstract
Carboxylates which contain aldehydes, acetals and/or unsaturated compounds and are obtained by reacting an olefinically unsaturated compound with carbon monoxide and an alkanol are purified by a process wherein the said carboxylates are treated with hydrogen at elevated temperatures in the presence of an acidic ion exchanger or zeolite doped with one or more metals of group VIII of the periodic table, and the resulting low and/or high boilers are separated off by distillation.
