Abstract
Dibenzyl carbonates are prepared by reacting a dialkyl carbonate with a benzyl alcohol in the presence of a basic catalyst and removing the highly volatile components and the catalyst from the reaction mixture. This process permits the preparation of benzyl carbonates in a simple manner, in good yields and without any particular technical safety arrangements.
