Abstract: A process for preparing carbamates is disclosed, in which:a stoichiometric or higher-than-stoichiometric amount of an alkyl carbonate or a cycloalkyl carbonate is reacted with an aliphatic, cycloaliphatic or aromatic amine, in a first reaction step, by operating in the presence of a carbamation catalyst, in order to produce a mixture of a carbamate and an urea,the urea contained in the reaction product from the first process step is reacted with carbonate, in a second reaction step, in order to produce the corresponding carbamate, andthe reaction mixture coming from the second process step is submitted to treatments in order to recover the carbamate.The process makes it possible high yields and high values of selectivity to the useful reaction product to be obtained.
