    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.
