Abstract
An alcohol is carboxylated into the corresponding carbonate by reacting the alcohol with oxygen and carbon dioxide in the presence of a catalyst system in the heterogeneous phase by introducing the reactants into a reactor charged with a catalyst, such as the complex system formed by copper and 4-vinylpyridine, causing the reactants to flow over the catalyst, and then withdrawing the products of the reaction and unconsumed reactants from the reactor.
