Latest Patents

Hildebrandt holds a patent for the "Continuous preparation of monoethanolamine, diethanolamine and triethanolamine." This patent describes a continuous process for the preparation of these amines by reacting ammonia and ethylene oxide in a liquid phase. The process utilizes water as a catalyst in a pressure column, where the heat of the reaction causes some ammonia to evaporate and condense at the head of the column. This ammonia is then reintroduced into the column. The reaction mixture is drawn off from the bottom of the pressure column and subsequently separated. The design of the pressure column is that of a reactive distillation column, which includes an evaporator at the bottom. The energy input via the evaporator allows for the control of the weight ratio of the amines produced, while the ratio of ammonia to ethylene oxide in the feed regulates the ammonia proportion in the bottom product.
