    Abstract: In the prodn. of trialkylamines (I) by reacting prim. alcohols (II) with NH3 in the presence of a hydrogenation/dehydrogenation catalyst (III), the novel features are that: a) the process is operated in the liquid phase; b) the NH3:(II) molar ratio = at least 1:4; c) the reaction is carried out in the presence of the water formed in the reaction; and d) (III) contains only Cu as catalytic hydrogenating/dehydrogenating metal.

    Abstract: The prepn. of high-molecular aldehydes (I) by the reaction of II with III: R9-CR8=CR7-CR5R6-CR3R4-CR2=CR1-CHO (I) R9-CR5=CR7-CR5R6-OR10 (II) C(H)R3R4-CR2=CR1-CHO (III) is carried out at increased temp. and between normal press. and 250 atmos. excess, in liquid phase. In the formulae, R1 and R2 are H, 1-4C alkyl or (alkyl-substd.) phenyl, R3, R5 and R7 are H or 1-4C alkyl, R4 is H or an (un)satd., (un)branched 1-12C (cyclo)aliphatic gp., R8 is 1-4C alkyl or, if R9 is phenyl, is H, R9 is an (un)branched, (un)satd. 1-12C (cyclo)aliphatic gp. in which C-C bonds may be interrupted by O or -O-CO-, or may be (alkyl-substd.) phenyl, and R10 is H or the acyl residue from a 1-5C carboxylic acid. I are raw materials for natural prods. and perfumes, e.g. beta-ionone, farnesol and phytol.

    Abstract: Prodn. of alpha,beta-unsatd. ketones of formula: R1-CH=C(R2)-CO-R3 (in which R1, R2 and R3 are opt. branched, opt. satd. aliphatic hydrocarbyl, cycloaliphatic radicals or aromatic radicals, which may be substd. with alkoxy gps.; or R2 is H; or R2 and R3 form together an alkylene bridge) by reaction between R1-CH2OH and R2 - CH2 - CO - R3 is improved in that the reaction is effected in the presence of a catalyst, in particular ZnO (pref.) and/or CdO and/or MnO in the liquid phase at 150-290 degrees C (pref. 180-280 degrees C). This method is esp. suitable for the prodn. of high mol.wt. ketones having multiple number of unsatd. bonds used as aroma agents, and valuable inters. such as pseudoionone. High yields selective w.r.t. alpha,beta-unsatd. ketones are obtd.
