Abstract
Alkanols can be carbonylated with carbon monoxide and oxygen at elevated temperatures in the presence of certain copper salts to form dialkyl carbonates. The invention also covers the carbonylation by recycling of the azeotropic mixture of methanol and the corresponding dimethyl carbonate.
