Abstract: Selective hydrogenation of alpha , beta -ethylenically unsaturated aldehydes (II) to corresponding unsaturated alcohols (I) comprises performing reaction in a reactor containing a liquid phase, suspended catalyst and optionally a gas phase, The liquid phase and gas phase (if present) are supplied to the reactor through a device (A) with openings or channels having a hydraulic diameter of 0.5-2 mm. Selective hydrogenation of unsaturated aldehydes of formula R R C=CR -CHO (II) to corresponding alcohols of formula R R C=CR -CH2OH (I) comprises performing the reaction in a reactor containing a liquid phase, suspended catalyst and optionally a gas phase. The liquid phase and optionally the gas phase are supplied to the reactor through a device (A) with openings or channels having a hydraulic diameter of 0.5-2 mm. R , R = H, optionally substituted mono- or polyunsaturated 1-20C alkyl (sic; some of the groups exemplified in the disclosure are saturated), optionally substituted aryl or optionally substituted heterocyclyl; R = H or 1-4C alkyl.

Abstract: The present invention relates to a process for the preparation of N-substituted 2,6-dialkylmorpholines of the formula I in which R 1 and R 2 , independently of one another, are hydrogen, alkyl or cycloalkyl, or R 1 and R 2 together with the carbon atom to which they are bonded are a 5- to 14-membered carbocycle, and R 3 and R 4 , independently of one another, are alkyl or cycloalkyl, by reacting at least one carbonyl compound of the formula II in which R 1 and R 2 have the meanings given above, with at least one morpholine of the formula III in which R 3 and R 4 have the meanings given above, in the presence of hydrogen and at least one metal-containing catalyst, wherein the active component of the catalyst consists essentially of platinum group metals.
