Abstract
1. Process for the preparation of organic carbonates by transesterification of a diester of carbonic acid and of at least one alcohol heavier than that or those formed by transesterification, in the presence of a transesterification catalyst based on a basic ionic salt, characterized in that the said transesterification operation is additionally carried out in the presence of a complexing compound capable of at least partially solubilizing the said salt in the reaction mixture by complexing its cation and at least partially dissociating the said salt.
