Abstract: Liquid mixtures containing aliphatic alcohols are separated, by distillation, into a higher-boiling alcohol-containing fraction and a lower-boiling fraction containing the other liquids, by carrying out the fractionation in the presence of water and of an alkanal and, over about 3/4 of the column height, in the presence of a non-volatile or only slightly volatile acid.

Abstract: The improved prepn. of Aldehydes are prepd. by the hydroformylation of olefinically unsatd. cpds., using catalysts contg. Co, by effecting the reaction also in the presence of noble metal catalysts selected from cpds. of Pt, Rn or Pd. The formation of isoaldehydes and polymsn. of starting materials, e.g. styrene is repressed. Rh catalysts are not required.

Abstract: Catalyst for hydrogenation of organic cpds. contains one or more complexes of Pd(O) on an inert carrier. This catalyst is very active, esp. with respect to hydrogenation of organic nitro or carbonyl cpds., nitriles, olefins and cycloolefins. The reaction is highly selective, esp. in the case of aromatic and polycyclic nitro cpds. The Pd(O) complexes are stable and firmly adhere to the carrier. The organic ligands protect Pd atoms against oxidation. The dispersion of Pd atoms is very fine. The pref. ligands include unsatd. ketones of formula (in which R1 and R6 are each H, 1-5C alkyl, phenyl or 5-8C cycloalkyl; and R2, R3, R4 and R5 are each H (pref.) or 1-5C alkyls).

Abstract: 1. A process for separating organic iodine compounds from carbonylation products of methanol, methyl acetate and dimethyl ether or from mixtures of such carbonylation products, wherein the iodine compounds are removed by liquid phase extraction with a non-aromatic hydrocarbon.

Abstract: A process is provided wherein acetaldehyde and methanol are obtained from reaction mixtures which result from the homologization of methanol and which in addition to acetaldehyde essentially contain acetaldehyde dimethylacetal, methanol, methyl acetate and water.

Abstract: In a new process for the prodn. of very finely divided carotenoids (carotenoid particle size essentially less than 1 micron), (A) a carotenoid is dissolved in a gas in the supercritical state (i.e. at a temp. above the critical temp. and under a pressure greater than the critical pressure); (B) the resulting soln. is dispersed in a suitable aq. colloidal matrix; (C) the dispersion is depressurised, and (D) the prod. is opt. converted in a conventional manner into a water-dispersible carotenoid-contg. powder mixt. The carotenoids are for use in colouring foodstuffs, pharmaceuticals or cosmetics, or for administration to poultry to give improved egg-yolk pigmentation.
