Abstract: Two methods are claimed for the production of ruthenium/iron/carbon carrier catalysts containing 0.1-5 wt.% iron as well as 0.1-10 wt.% ruthenium on a carbon carrier. Two methods are claimed for the production of ruthenium/iron/carbon carrier catalysts containing 0.1-5 wt.% iron as well as 0.1-10 wt.% ruthenium on a carbon carrier. The first method involves: (i) addition of a base to a mixture in water of the carrier and a solution containing the catalytically-active ruthenium and iron components so as to effect simultaneous precipitation onto the carrier; (ii) separating the catalyst from the aqueous phase of the suspension; (iii) drying the catalyst; (iv) reducing in a hydrogen stream at 400-600 deg C; and (v) forming the catalyst in a difficultly-flammable liquid or passivating it with a diluted air stream. The second method proceeds as per step (i) above but this is followed by: (iia) reduction of the catalyst by addition of an aqueous reductant; (iiia) separating from the aqueous phase of the suspension; and (iva) washing with water. An Independent claim is included for the use of the catalyst is in selective liquid hydrogenation of carbonyl compounds of formula R C(O)R (I) to the corresponding alcohols of formula R C(OH)HR (II). R and R = H, optionally mono- or poly-unsaturated, optionally substituted 1-20C alkyl, optionally substituted aryl or optionally substituted heterocyclic group.

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.

Abstract: Preparation of ethyleneamines by reacting monoethanolamine (MEOA) with ammonia in the presence of a catalyst in a reactor (1) and separating the resulting reaction product, where ethylenediamine (EDA) obtained in the separation is reacted in a separate reactor (2) in the presence of a catalyst to give diethylenetriamine (DETA), and the resulting reaction product is passed to the separation of the reaction product resulting from reactor 1.

Abstract: A process is described for selectively hydrogenating citronellal to citronellol in which a liquid phase, in which the citronellal is dissolved and particles of a catalyst are suspended which is capable of preferentially hydrogenating carbon-oxygen double bonds over carbon-carbon double bonds, is conducted through a device which inhibits the transport of the catalyst particles in the presence of a hydrogen-containing gas.
