    Abstract: The invention relates to a process for the prepartaion of alkanesulfonic acids, comprising the following steps:(a) oxidation of alkylmercaptans and/or dialkyl disulfides and/or dialkyl polysulfides having from three to nine sulfur atoms with nitric acid to form alkanesulfonic acids, water, nitrogen oxides and other byproducts,(b) regeneration of the nitrogen oxides obtained from step (a) with oxygen to give nitric acid and recycling of the nitric acid to step (a),where steps (a) and (b) are carried out in reaction chambers separate from one another.

    Abstract: Novel esters of specific formulas are new. Novel esters of formulae (Ia) and (Ib) , their esters, optically active forms, tautomers, racemates, distereomer mixtures or salts are claimed: R = phenyl or 1-6C alkyl or alkoxyalkyl, where the alkoxy is a combination of an alkoxy group with an oxygen atom, e.g. (m)ethoxy, propoxy, butoxy or pentoxy. Independent claims are included for: (1) preparation of these esters and their mixtures by radically reacting an acetate of formula (II) with 1,9-decandiene; (2) preparation of 1,15-hexadecadiones by reacting the ester of (II) with 1,9-decandiene and decarboxylating; (3) preparation of muscones of formula (III) by further reacting this product in the gaseous phase to give muscones, cyclizing in a mixture with unsaturated muscone derivatives and hydrogenating to muscone.

    Abstract: The invention relates to the preparation of aliphatic -aminonitriles by partial hydrogenation of aliphatic dinitriles at elevated temperature and higher pressure, in the presence of a solvent and catalyst. Catalyst, containing the following is used: (a) compound based on metal, e.g. nickel, cobalt, iron, ruthenium and rhodium; (b) from 0.01 to 25 wt.% promotor to component (a) based on metal such as palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminium, tin, phosphorus, arsenic, antimony, bismith, silicon, titanium, zirconium and the rare earth elements, and (c) from 0 to 5 wt.% compound to component (a) based on alkali or alkaliearth metal, provided that component (a) is different from an iron-based compound or from iron, as well as from the metals cobalt, ruthenium or rhodium when component (b) is promotor based on a metal from the group containing titanium, managanese, chromium and molybdenum. An additional condition is that when component (a) is a compound based on ruthenium or rhodium separately, or of ruthenium and rhodium, or of nickel and rhodium, promotor (b) can optionally be dropped. 8 claims

    Abstract: 2-Cyclododecyl-propanol [sic], which is in demand as musk scent, is prepared in an advantageous industrial process by reacting cyclododecene with an excess of propionic acid or of a propionic acid derivative in the presence of catalytic amounts of a free-radical initiator, and subsequently catalytically hydrogenating the 2-cyclododecylpropionic acid which is formed or the corresponding 2-cyclododecylpropionic acid derivatives.

    Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partial hydrogenation of aliphatic alpha,omega-dinitriles at elevated temperatures and superatmospheric pressure in the presence of a solvent and of a catalyst by a process which comprises using a catalyst which (a) contains a compound based on a metal selected from the group consisting of nickel, cobalt, iron, ruthenium and rhodium and (b) contains from 0.01 to 25% by weight, based on (a), of a promoter based on a metal selected from the group consisting of palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminum, tin, phosphorus, arsenic, antimony, bismuth and rare earth metals and (c) from 0 to 5% by weight, based on (a), of a compound based on an alkali metal or on an alkaline earth metal. with the proviso that the component (a) is not based on iron or iron and one of the metals selected from the group consisting of cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group consisting of titanium, manganese, chromium and molybdenum, and with the further proviso that, when a compound based on only ruthenium or rhodium or ruthenium and rhodium or nickel and rhodium is selected as component (a), the promoter (b) may be dispensed with.

    Abstract: Aliphatic alpha , omega -aminonitriles are prepared by partial hydrogenation of aliphatic alpha , omega -dinitriles at elevated temperatures and superatmospheric pressure in the presence of a solvent and of a catalyst, by a process in which the catalyst used is obtainable by thermal decomposition of a metal compound selected from the group consisting of metal carbonyl compounds, metal salts of C1-C6-carboxylic acids and C2-C6-dicarboxylic acids and metal complexes with diketones to give the corresponding metal and/or a metal oxide thereof, with the proviso that the metal used is nickel or cobalt.
