Abstract: Preparation of 2-substituted 6-methylanilines by reaction of anilines with methanol in the gas phase in the presence of supported catalysts which comprise a) vanadium pentoxide and/or chromium (III) oxide as catalyst and b) aluminium oxide and, if appropriate, copper (II) oxide and/or nickel (II) oxide as carrier, at a temperature between 250 and 550 DEG C. The 2-substituted 6-methylanilines prepared by the process are useful starting materials for the synthesis of colours, pharmaceuticals and crop protection agents.

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.
