摘要
The invention concerns a method for evaporating aminonitrile and water in conditions limiting or eliminating the formation of heavy by-products in particular amino-carboxylic acid oligomers. To avoid said inconvenience, said method for evaporating aminonitrile and water is characterised in that the water in vapour state serves as balance gas for evaporation.
