Abstract
Production of aldehydes and alcohols by oxo synthesis involving the reaction of olefinic compounds with carbon monoxide and hydrogen at elevated temperatures and under elevated pressures in the presence of amine-modified carbonyl complexes of cobalt or rhodium. Diamino diphenyl alkanes are used as modifying agents.
Claims6
In a process for the production of aldehydes and alcohols by oxo synthesis involving the reaction of an olefin having 2 to 20 carbon atoms with carbon monoxide and hydrogen at pressures ranging from 1 to 300 atmospheres in the presence of an amine and a carbonyl complex of cobalt, the improvement comprising using as said amine a diamino diphenyl alkane having the formula ##STR2## where R.sup.1 and R.sup.2 stand for alkyl radicals of 1 to 4 carbon atoms, R.sup.3 stands for an alkylene or alkylidene radical of 1 to 3 carbon atoms, X and Y respectively stand for hydrogen or methyl, and n is 0,1 or 2 at temperatures in the range of 100.degree.-140.degree. C.
