    摘要： A new process for the production of high purity (cyclo)aliphatic diurethanes from (cyclo)aliphatic diamines, alcohols and urea in a multistep reaction in which (1) urea is reacted with alcohol with elimination of ammonia, (2) diamine is then introduced into the reaction mixture, optionally in the form of a solution in alcohol, and reacted with continuous release of ammonia and (3) the reaction mixture is freed from volatile components by distillation. The diurethanes produced by this process are useful as starting materials for the production of the corresponding diisocyanates by thermal urethane cleavage.
