Abstract: Cpds. of formula (I) (where each R is H (prefd.) or an aliphatic gp.) are useful as inters. for dyes, pesticides and plastics stabilisers, are themselves useful as stabilisers (e.g. for poly-olefins and polyamides), and are specific solvents in the molten state. They can be prepd., e.g., by reducing the corresp. butan-2-one.

Abstract: A process for the prepn. of higher ketones of formula: R'CH2CH2COR2 comprises the reaction of an aldehyde of formula (I): R1-CHO with ketones of formula (II) CH3COR2 at 80-280 degrees C in the presence of hydrogen and a catalytic system, which contains an oxide or salt of a rare earth metal or mixts. of these and one or more Group VIII metals. In the above, R' is 1-20C alkyl, esp. 1-5C), aryl or cycloalkyl opt. substd. by alkyl, or 7-20C (pref. 7-10 C) aralkyl; the above gps. may also be substd. by OH or alkoxyl gps. inert to the reaction conditions; R2 is the same as R'. Typical cpds. are methyl isoamyl ketone used as a solvent and intermediate and 4-phenyl-butan-2-one used in perfumery. As a result of the catalyst which favours both the condensation and hydrogenation steps, the process is more selective, simpler, cheaper and gives higher yields compared with previous processes. Using acetone and methyl propanol, the catalyst is 10% Ni, 10% Co, 10% rare earth oxides (95% Nd2O3) on an alumina support giving a mixture contg. 40.8% starting materials and 34.3% 5-methylhexane-2-one. The pref. reaction temp. is 140-220 degrees C.

Abstract: New 3-methyl-pentan-2,5-diol-bis(2-cyanoethyl) ether is of formula NC-(CH2)2-O-(CH2)2-CH(CH3)-(CH2)2-O-(CH2)2-CN (I) (I) is an intermediate in the prodn. of the corresponding diamine which in turn can be used to prepare epoxy resins and polyurethanes. (I) is also useful as a polar solvent and an additive for minerals and propellants. (I) is made by reaction of 2 mols acrylonitrile and 3-methyl-penta-1,5-diol.
