Abstract: Aldehydes are obtained from the gaseous product of the hydroformylation of olefinically unsaturated compounds using a rhodium catalyst by a process (cf. FIG. 2) in which (a) this gaseous product is introduced, without being cooled or depressured, into a distillation column D, (b) the top fraction from this column is cooled in a condenser K so that the greater part of the aldehydes contained therein is condensed, (c) the condensate is separated, in a separator A, into a gas phase and a liquid phase, (d) the gas phase from A, after waste gas has been separated off, is again brought to the hydroformylation pressure by means of a compressor P, and is returned to the reactor as a recycle gas, (e) the liquid phase from A is returned to D, and (f) the aldehydes are taken off from column D as liquid bottom products and/or as a vaporous side stream.

Abstract: Unbranched aldehydes are made by hydroformylation of alkylenically unsatd. cpds. with 2-20 C with CO and H2 at elevated temps. and pressures in the pres. of cobalt carbonyl cpds. by (a) treating aq. soln. of cobalt salts with CO and H2 at 50-200 degrees C and 100-400 atm. in thepres. of active carbon, zeolites or basic ion exchangers charged with cobalt carbonyl, (b) in a second stage, without releasing the pressure, extracting the mixture at 20-100 degrees C and 100-400 atm. with a satd. hydrocarbon or with the unsatd. cpd. to be hydroformylated (provided this is insoluble in water and is liquid under the prevailing conditions) or with (hydrogenated) oxo reaction products is water insoluble, (c) removing the aq. phase and (d) subjecting the resulting carbonyl complex-contg. organic phase and the mixture of CO and H2 (after addition of the alkylenically unsatd. cpds. to be hydroformylated if not used in stage (b)) to hydroformylation at 70-170 degrees C and 100-400 atm. Suitable starting materials are 2-20C alkenes with terminal double bonds, alkene mixtures made by cracking waxes and polymers of ethylene, styrene, butyl, acrylate, etc. Process gives good selectivity to prodn. of unbranched aldehydes, useful in the prodn. of alkanols for washing agents and plasticisers, etc.

Abstract: Preparation of C3- to C25-alkanols by catalytic hydrogenation of corresponding crude C3- to C25-alkanols, as obtained in the cobalt-catalyzed hydroformylation of C2- to C24-olefins, by partial 80-95% hydrogenation conversion in a first stage using a silica supported nickel and molybdenum oxide catalyst and then completing the conversion in a second stage using a cobalt catalyst containing copper, manganese, molybdenum and,optionally other activating additives. The process is especially adapted to the economic preparation of C9-C11- and C13-C15-alkanols which are used to prepare high-grade plasticizer esters.
