A hydroformylation process for producing relatively low ratios of normal to branched aldehyde product, wherein olefin having from 2 to 20 carbons, preferably 3-10 carbons, and most preferably one or more of ethylene, propylene and 1-butene is contacted in a reaction zone at a temperature of from about 60.degree. C. to about 250.degree. C., preferably from about 150.degree. C. to about 200.degree. C., and a pressure of from about 750 psig to about 10,000 psig, preferably from about 3,000 psig to about 4,000 psig, with hydrogen and carbon monoxide, in the presence of a catalyst containing from about 10.sup.-6 to about 10.sup.-3, preferably from about 5.times.10.sup.-5 to about 5.times.10.sup.-4, and most preferably from about 1.5.times.10.sup.-4 to about 2.6.times.10.sup.-4 moles of osmium per mole of said olefin and also containing cobalt, and molar ratio of Os/Co being from about 1/10 to about 1,000/1, preferably from about 1/1 to about 20/1, and most preferably from about 5/1 to about 15/1, for a sufficient period of time to permit reaction of said olefin with said hydrogen and carbon monoxide to form aldehyde product.
