Abstract: p-Alkoxycyclohexylalkanols and their esters of the general formula I where R1 is C1-C7-alkyl, in particular tert.-butyl, or is cyclohexyl, R2 is C1-C3-alkyl, in particular methyl or ethyl, and R3 is hydrogen, acetyl, propionyl or butyryl, and scent compositions containing these compounds I and processes for their preparation. The novel compounds have fine woody or sandalwood notes and can be used as scents and as components of scent compositions.

Abstract: The parent patent describes a method of carrying out exothermic reactions between a gas and liq in the presence of solid catalysts; the gas and liq pass in parallel flow through a long reaction vessel contg packing, the quantity of liq passed through the vessel being such that, with const gas flow the increase in press difference between the vessel ends is >=2- fold, but the fluctuations in press difference normally caused by pulsation are eliminated. In the Patent of Addition, the method is applied to reactions which do not take place in the presence of solid catalysts, but which occur spontaneously or in the presence of dissolved or finely suspended catalysts, opt without special heat conditioning; instead of the catalyst, any kind of packing is used for the reaction vessel.

Abstract: Hydrogenation of aromatic cpds. to the corresp. cycloaliphatic cpds. with H2-contg. gases, is effected, with 98-100% yields, at 30-250 degrees C >50 atmos. press. using a catalyst prepd. by pptn. of a Ru hydroxide, e.g. Ri(OH)4 prepd. from ruCl3.H23. Pref. uses are hydrogenation of mono- or polynuclear aromatic mono- or diamines, partic. 4.4'-diaminodiphenylmethane (I) and Me-substd. derivs. mono- nuclear nitriles or aromatic ketones, substd. mono-nuclear nitriles or monoamines with additional NO2-substituents; mono-nuclear aromatic mono- and dicarboxylic acids and Me esters; mono- and di-nuclear hydrocarbons; N-contg. heterocycles.

Abstract: 1,268,653. Trimethylbenzoquinone. BADISCHE ANILIN- & SODA-FABRIK A.G. 12 Aug., 1969 [13 Aug., 1968], No. 40176/69. Heading C2C. Trimethyl-p-benzoquinone is prepared by reacting 2,3,6-trimethylphenol with oxygen in the presence of a cobalt complex of the formula where R 1 , R 2 , R 3 and R 4 are hydrogen or an aliphatic radical or R 2 and R 3 and the two adjacent carbon atoms form an aromatic ring and in the presence of an open or cyclic amide having two substituents other than hydrogen on the nitrogen atom as solvent.
