Abstract: A process for the preparation of tertiary alkylamines having a total of up to 9 carbon atoms by reacting a dialkylamine with a C2-C4-alcohol in the presence of a hydrogenation/dehydrogenation catalyst which contains essentially only copper as the hydrogenating/dehydrogenating catalytic metal is proposed, wherein the reactants (a) are present in the liquid phase, (b) contain alkali metal and/or alkaline earth metal oxides and/or hydroxides and (c) are reacted in a molar ratio of dimethylamine to alcohol of from 1:10 to 10:1 and (d) in the presence of the water formed during the reaction.

Abstract: A process for the production of alpha , beta -unsaturated ketones by reaction of an aldehyde with a ketone in the presence of a catalyst consisting essentially of zinc oxide in the liquid phase. The ketones obtained are suitable in some cases as solvents and in some cases as intermediates for the production of valuable odorants, dyes, plastics and especially natural substances.

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: Title cpd. is an aroma agent having the scent and taste of raspberries. It is produced in high yields by the one-stage title process which is much simpler and cheaper than the known production methods because inexpensive starting materials are used. The reaction is carried out at -10 degrees to +80 degrees C (preF. between -2 degrees and +30 degrees C) in the presence of conc. H2SO4 or H3PO4, or gaseous HCl in a solvent.

Abstract: Aliphatic N,N-dialkylamino-alcohols of formula HO-A-NR1R2 (I) are mfd. by reaction of a diol HO-A-OH (II) with a sec.-amine HNR1R2 (III), at 150-250 deg.C and 40-250 bar in the presence of hydrogen at a partial pressure of 2-60 bar, a Cu-based hydrogenation / dehydrogenation catalyst (IV), 1-20wt.% water, and a basic alkali or alkaline earth cpd. in the liq. phase. A = at least 2C aliphatic bridging gp.; R1, R2 = 1-6C alkyl, opt. bonded to a 5- or 6-membered ring. Specifically, (II) is a linear 2-8C alpha,omega- alkanediol, opt. with max. 3 CH2 gps. replaced by ether O; (III) is dimethyl-or diethyl-amine; (IV) is made by redn. of mixed Cu/Al carbonates obtd. by pptn. from aq. solns. of Cu and Al salts with alkali metal carbonate, or by redn. of Cu formate.
