    Abstract: Processes comprising: (a) providing a first reactant comprising a bioethanol; and (b) reacting the first reactant with a second reactant comprising a component selected from the group consisting of ammonia, primary amines, secondary amines and mixtures thereof, in the presence of hydrogen and a catalytically effective amount of a heterogeneous hydrogenation/dehydrogenation catalyst to form an ethylamine; wherein the catalyst has been activated at a temperature of 100 to 500° C. for at least 25 minutes; wherein prior to activation the catalyst comprises: (i) 20 to 65% by weight of a support material comprising one or both of zirconium dioxide (ZrO2) and aluminum oxide (Al2O3), (ii) 1 to 30% by weight of oxygen-comprising compounds of copper, calculated as CuO, and (iii) 21 to 70% by weight of oxygen-comprising compounds of nickel, calculated as NiO; and wherein after activation the catalyst has a CO uptake capacity of >110 mumol of CO/g of the catalyst.

    Abstract: Process for separating triethanolamine continuously by distillation from a mixture of monoethanolamine, diethanolamine and triethanolamine together with ethanolamine ethers and water obtained by reaction of ammonia with ethylene oxide in the liquid phase under superatmospheric pressure and at elevated temperature, in which the mixture is distilled in two stages. The low-boiling fraction and the high-boiling fraction are taken off and discharged in the first stage and the intermediate-boiling fraction comprising >99.4% by weight of triethanolamine and
