Abstract

A method is suggested to produce oxygenated compounds from carbon monoxide, hydrogen and olefin-containing raw material. The catalyst is the residue obtained after evaporation of oxo synthesis products. To simplify the process and make it operable in continuous mode, the evaporation is carried out at the minimum partial pressure of hydrogen and at increased pressure of carbon monoxide (190 atm) at 170-180C; the obtained residue is used as the catalyst for oxo synthesis. The advantage of the proposed method is that the catalyst of any concentration is obtained without losses for thermal decomposition and volatilization, while the target products are practically free of cobalt.
