Abstract: The present invention relates to a process for purifying ethylenediamine (EDA) by distillation, wherein the process comprises the steps a) and b). In step a), a mixture (G1) comprising water, EDA and N-methylethylenediamine (N-MeEDA) is fed into a distillation apparatus (D1), and the major part of the water comprised in the mixture (G1) is separated off overhead at a pressure of greater than 4.8 bara. From the bottom of (D1), the water-enriched mixture (G2) is fed into a distillation apparatus (D2) in step b). At the top of (D2), the major part of the N-MeEDA is distilled off. The stream (S3) obtained from the bottom of (D2) comprises EDA, with the components water and N-MeEDA comprised in the mixture (G1) having been largely or completely removed. Further distillation steps can optionally be carried out in order to obtain pure EDA, for example when diethylenetriamine (DETA) is additionally comprised in the mixture (G1). If ammonia is additionally comprised in the mixture (G1), an ammonia removal is preferably additionally carried out before carrying out the step a) in the process of the invention.

Abstract: A method for removing methoxyethanol from a mixture comprising methoxyethanol and morpholine makes use of the selective adsorption of methoxyethanol onto a mixed oxide comprising a spinel phase. The mixed oxide comprises 20 to 30% by weight MgO and 80 to 70% by weight Al2O3. The spinel phase has the formula MgAl2O4. The mixture is a pre-purified reaction output of the reaction of diethylene glycol with ammonia in the presence of an amination catalyst.
