Abstract: A process for continuous production of C2-C4-monoalkanolamines by reaction of a corresponding C2-C4-alkylene oxide with a molar excess of ammonia (NH3), wherein aqueous ammonia is employed, in the liquid phase and in the presence of an acidic cation exchanger as catalyst which contains a crosslinked copolymer comprising acidic functional groups as the carrier matrix, wherein the cation exchanger has a total exchange capacity of not less than 1.8 eq/L.

Abstract: A process for hydrogenating a hydrogenatable organic compound in a reactor including a fixed catalyst bed. The fixed catalyst bed includes monolithic shaped catalyst bodies having pores and/or channels. The catalyst bodies include at least one element selected from Ni, Fe, Co, Cu, Cr, Pt, Ag, Au, Pd, Mn, Re, Ru, Rh and Ir. The CO content in the gas phase within the reactor during hydrogenation is within a range from 0.1 to 10,000 ppm by volume. In any section in the normal plane to flow direction through the fixed catalyst bed, at least 90% of the pores and channels have an area of not more than 3 mm2.
