    Abstract: An improvement in the process for the manufacture of predominantly straight-chain aldehydes by hydroformylation of olefinically unsaturated compounds of 2 to 20 carbon atoms with carbon monoxide and hydrogen in which, in a first stage, aqueous cobalt solutions are treated with carbon monoxide and hydrogen at temperatures of 50 DEG to 200 DEG C and pressures of 100 to 400 atmospheres in the presence of active charcoal, zeolites or basic ion exchangers which are charged with cobalt carbonyl, in a second stage cobalt carbonyl-hydride is extracted from the reaction mixtures thus obtained, at temperatures of 20 DEG to 180 DEG C and pressures of 1 to 400 atmospheres, by means of olefinically unsaturated compounds which must be water-insoluble and liquid under the conditions used, the aqueous phase is separated off and the organic phase is transferred to a third stage and in this stage, after introducing olefinically unsaturated compounds if the latter have only been used partially for the extraction, the hydroformylation is carried out at temperatures of 70 DEG to 170 DEG C and pressures of 100 to 400 atmospheres, the improvement being that the extraction in the second stage is carried out as a co-current extraction whilst maintaining turbulent flow.

    Abstract: A process is disclosed for producing amines of general formula (I) in which: R , R , R , R , R , R stand for hydrogen, C1-C20-alkyl, C2-C20-alkenyl, C2-C20-alkinyl, C3-C20-cycloalkyl, C4-C20-alkyl-cycloalkyl, C4-C20-cycloalkyl-alkyl, aryl, C7-C20 alkylaryl or C7-C20-aralkyl; R and R together represent a saturated or unsaturated C3-C9 alkylene di-chain; and R or R stand for C21-C200-alkyl, C21-C200-alkenyl or together stand for a C2-C12 alkylene di-chain. The process involves reacting the olefins of general formula (II), in which R , R , R , R have the above meanings, with ammonia or primary or secondary amines of general formula (III), in which R and R have the above meanings, at temperatures of 200-350 DEG C and pressures of 100-300 bar in the presence of a heterogenous catalyst in the form of zeoliths of type SSZ-26, SSZ-33, CIT-1 or mixtures thereof.
