Abstract

PURPOSE: To make the liquid phase separation of a catalyst possible without heating by first releasing pressure from the oxo reaction liquid contg. the catalyst then acting polyethylene glycol or the like thereto.
CONSTITUTION: Oxo reaction of an olefinic compound is carried out under pressurizing of carbon monoxide and hydrogen by using the catalyst produced by reaction of a cobalt compound and 2-pyridine. At this time, the pressure of the oxo reaction liquid contg. said catalyst is released, and polyethylene glycol or dimethyl formamide is acted upon the hydrocarbon soln. layer contg. the product of the oxo reaction. Then, the catalyst liquid phase is separated easily from this hydrocarbon liquid phase without heating the reacting liquid.
