Abstract: Process for the preparation of 3-aryl-isobutanols of the general formula I … … in which… R and R are hydrogen or an alkyl or cycloalkyl radical with up to 8 C atoms, preferably an alkyl radical with 1 to 4 C atoms,… which is characterised in that arylcarbinols of the general formula II … … are reacted with n-propanol in the presence of catalytic amounts of an alkali metal hydroxide or alkali metal oxide at 250 to 350 DEG C in a closed reaction vessel. … The process is particularly important for preparing 3-aryl-isobutanols of the formula I in which R is an alkyl radical with 1 to 4 C atoms and R is hydrogen. The p-methyl-, p-isopropyl- and p-tert.-butylphenylisobutanols obtained in this way in very high selectivity are valuable precursors for the fragrances jasmorange, cyclamenaldehyde and Lysmeral (Lilial ) which are in high demand.

Abstract: Preparation of C3-C5-alcohols by hydrogenation of the corresponding aldehydes with hydrogen by means of a catalyst which, in ready-to-use but not yet reduced form, contains 5 to 70 % by weight of Al2O3 and/or Fe2O3 and 30 to 95 % by weight of a mixture of 100 parts by weight of NiO, 20 to 40 parts by weight of CuO, 0.5 to 6 parts by weight of MoO3 and 0 to 10 % by weight of Mn3O4, the catalyst having been prepared by reaction of an aqueous solution of the corresponding metal salts with an alkali metal carbonate solution under specified conditions, followed by drying, washing and heating.

Abstract: The use of ether nitriles (I) as odourants is claimed. (I) are of formula: R-(CH2)m-A-(CH2)n-O-(CH2)2-CN (where R = H, (CH3)2CH- or CH3C(=CH2)-; A = a C-C bond or -C(CH3)=CH-; m = 1-8 and n = 1-5 with the proviso that the total no. of C in (I) = 7-15). (I) may be prepd. (see DT 2121325 and DT 2217494) by reacting corresp. alcohols with acrylonitrile. (I) have a floral-aromatic-fruity odour.

Abstract: In continuous prodn. of poly(alkoxypropylamines) of formula (H2N-CH2CH2CH2O)nR (where n is an integer 2 to 6, and R is residue of a 2-6-hydric alcohol), using a Co-catalyst e.g. Co-oxide on a silica gel carrier, in the liquid phase, the catalyst is pre-treated with some other nitrile (e.g. an aliphatic or aromatic nitrile) in presence of H2. Claimed process minimises risk of decomposition of catalyst.
