Abstract
Disclosed is a process for the hydroformylation of olefinic material in general, and more particularly concerns the hydroformylation of olefins of 2 to 20 carbons, preferably of 3 to 10 carbons for the production of relatively high proportions of branched aldehydes, comprising contacting olefinic material in a reaction zone at a temperature of from about 60.degree. C. to about 250.degree. C. and a pressure of from about 750 psig to about 10,000 psig with hydrogen, carbon monoxide, and a catalyst consisting of a mixture of unmodified cobalt and unmodified rhodium in a molar ratio range of from about 0.5 to about 100, wherein for each mole of olefin there is present from about 1.times.10.sup.-7 to about 1.times.10.sup.-5 moles of rhodium and from about 1.times.10.sup.-7 to about 1.times.10.sup.-4 moles of cobalt, for a sufficient period of time to permit reaction of the olefinic material with the carbon monoxide and hydrogen to form aldehyde product.
