摘要： A process to convert the cyclic monourea of ethylene amine compounds (U-EA) into ethylene amine compound (EA) is provided. The process may include performing a reactive separation step using a reaction mixture containing the cyclic monourea, wherein one cyclic monourea (U-EA) reacts with another cyclic monourea (U-EA) to transfer its urea unit thereto. The process may further include separating the obtained ethylene amine compound (EA) without urea unit from the reaction mixture.
