Abstract: Heterocyclic aldehydes having the formula (I), in which A, B stand for possibly substituted methylene groups; m, n = 1 to 5 and m+n > 2, are prepared by hydrogenating carboxylic acids having the formula (IIa) or their esters (IIb) derived from C1-C10 alcohols at 200 to 450 DEG C in the presence of a catalyst. The products thus obtained are useful as precursors of cyclohexenone type herbicides.

Abstract: The muscone of the formula I is prepared by bringing open-chain 2,15-diketones of the general formula II CH3-CO-X-CO-CH3 (II> in which X represents one of the radicals -(-CH2-)@(a> -CH=CH-(-CH2-)@CH=CH- (b> -CH2-CH=CH-(-CH2-)@CH=CH-CH2- (c> -CH2-CH2-CH=CH-(-CH2-)@CH=CH-CH2-CH2- (d) or -CH2-CH2-CH2-CH=CH-(-CH2-)@CH=CH-CH2-CH2-CH2- (e), into contact at temperatures of 300 to 400 DEG C in the presence of 5 to 15 % by weight of water, relative to the amount of catalyst, in the gas phase over a fixed-bed catalyst which contains TiO2, CeO2 or ThO2 as the catalytically active compound and hydrogenating catalytically the unsaturated cyclic ketone formed in this reaction by intramolecular aldol condensation. Furthermore, the open-chain unsaturated ketones of the formulae IIb, IIc and IId and advantageous processes for their preparation and their use as intermediates for a simple industrial muscone synthesis are claimed.

Abstract: The application relates to the preparation of a sulphur-free iron-oxide- and chromium-oxide-containing high temperature conversion catalyst, an iron oxide being used which is prepared from iron carbonyl and which has a mean grain size below 10 mu m and a specific surface area of more than 10 m /g. The chromium oxide component is applied to the iron oxide by precipitation. The chromium component used is CrO3 and is precipitated as insoluble chromium(III) compounds by reducing agents.
