A process for the preparation of 2-(2-aminoethoxy) ethanol (2AEE) and morpholine with 2AEE: morpholine 〉3

摘要

The present invention is selective for 2AEE remarkably high, that is 3 2AEE: relates to a method for producing a non-2AEE having a morpholine. DEG and ammonia, and the reaction temperature in a continuous mode in a hydrogen environment in the presence of a catalyst at 150 ℃ to 250 ℃ and pressure 10 bar to 20 bar, the product is separated by distillation. The catalyst used is a metal or a metal oxide or oxide on a silica or alumina support. Ammonia: DEG molar ratio of 20, and; Hydrogen: the molar ratio of DEG is 1, preferably 1 - 30. The reactants are fed to the downstream mode, as the case may be. The catalyst charged into the reactor has a 10% to 70% of the same metal, and its oxide or metal oxide and a metal content of the support.
