Patent number: 9914693Abstract: The present invention relates to a process for preparing ethylenediamine (EDA), where the process comprises the steps a) to c). In step a), formaldehyde is reacted with hydrocyanic acid (HCN) to form formaldehyde cyanohydrin (FACH), where the hydrocyanic acid is completely free or largely free of sulfur dioxide (SO2). The FACH prepared in this way is reacted with ammonia (NH3) to form aminoacetonitrile (AAN) in step b), whereupon a hydrogenation of AAN in the presence of a catalyst to form EDA is carried out in step c).Type: GrantFiled: February 12, 2014Date of Patent: March 13, 2018Assignee: BASF SEInventors: Hermann Luyken, Stephanie Jaegli, Michael Lorenz, Gordon Brasche, Markus Jegelka, Barbara Becker, Robert Baumann, Johann-Peter Melder, Boris Buschhaus, Thomas Krug

Patent number: 9828329Abstract: 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).Type: GrantFiled: March 11, 2015Date of Patent: November 28, 2017Assignee: BASF SEInventors: Hermann Luyken, Stephanie Jaegli, Michael Lorenz, Gordon Brasche, Markus Jegelka, Barbara Becker, Robert Baumann, Johann-Peter Melder, Boris Buschhaus, Thomas Krug
