Abstract:
A process for preparing dibenzyl carbonates of the formula (I) whereinR represents a C1-C6-alkyl group, a C6-C12-aryl group or a halogen, and n represents zero or an integer from 1 to 5, comprising: (A) reacting, in the presence of a basic catalyst, (1) a dialkyl carbonate of the formula â€ƒin which Râ€² represents a C1-C4-alkyl radical, with (2) a benzyl alcohol of the formula â€ƒin which R and n are as defined under formula (I); and (B) removing highly volatile components and the catalyst from the reaction mixture, wherein from about 0.0001 to about 20 mol % of a basic catalyst, based on the dialkyl carbonate, is used.
