    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: In the production of aliphatic alpha ,w-aminonitriles (I) by catalytic partial hydrogenation of aliphatic alpha ,w-dinitriles (II), the catalyst contains: (a) iron (Fe) and/or Fe compound(s); (b) 0.01-5 wt.%, with respect to (a), of a promoter based on group 2, 3, 4 or 5 elements selected from aluminium, silicon, zirconium, titanium and vanadium; and (c) 0-0.5 wt.%, with respect to (a), of an alkali(ne earth) metal compound. Preferably component (a) is based on Fe oxide(s) and (b) on Al, Si and V. The catalyst is optionally supported. Simultaneous production of ACN and HMD from ADN comprises: (1) catalytic partial hydrogenation of ADN to a mixture containing ACN, HMD and ADN; (2) separation of ACN and HMD from the mixture; (3) adding an acid or acid ion exchanger to the mixture containing ADN especially in an amount of 0.01-10 wt.% with respect to ADN, ADN is then separated. If ADN is separated by distillation, the acid used has a boiling point above that of ADN at the pressure used for distillation and a pKa value \} 10. The purified ADN is then recycled. Hydrogenation may be carried out in a suspension or stationary bed reactor.

    Abstract: The preparation of enol-ethers of formula R3R4C=C(OR1)R2 is by gas phase reaction at 100-550 (especially 200-350) degrees C and 0.001-5 bar of acetals or ketals of formula R3R4HC-C(OR1)(OR1')R2 on a heterogeneous highly porous catalyst which is an oxide of a Gp. II, III or IV or sub-Gp. II or IV element, the catalyst having a pH of 7-14, a porosity of 40-80% and a BET surface area of 0.5-250 m /g. R1-5 = 1-20 C alkyl, 2-20 C alkenyl or 7-20 C phenylalkyl; R2-4 = H, aryl, CN, COOR5, 1-12 C alkyl (optionally 1-3 times substituted or interrupted by COOR5, CO, CN or 1-12 C alkoxy), aryl or 7-12 C phenylalkyl (each optionally 1-3 times substituted by 1-12 C alkyl, 1-12 C alkoxy, halogen or CN); R2/R4 or R3/R4 = together 3-10 C alkylene or 2-20 C alkylidene; and R1' = R1, but not necessarily the same.
