Abstract: 1308567 Production of aldehydes and ketones by the oxo process BADISCHE ANILIN- & SODA-FABRIK AG 24 July 1970 [26 July 1969] 35891/70 Heading C2C Aldehydes and/or alcohols are produced by the oxo process by reacting an olefinically unsaturated compound with carbon monoxide and hydrogen in the presence of a cobalt carbonyl compound at elevated temperature, super atmospheric pressure and the reactants being introduced into the reaction zone at high speed wherein the reactants are introduced into a mixing zone which is located in the reaction zone in which it extends in the direction of introduction of the reactants, the mixing zone having a diameter which is from twice to fifty times the mean diameter of the stream of reactants supplied and having a length which is from three to thirty times its hydraulic diameter. The diameter of a stream of reactants is the diameter of a circle having the same area as the cross-section of a wand nozzle or other inlet opening and the hydraulic diameter is the diameter of a cylindrical tube which exhibits the same pressure drop as the mixing zone in question having the same length and the same throughput.

Abstract: The formation of an emulsion when working up reaction mixtures containing butyraldehydes and cobalt is avoided by a treatment with gases containing molecular oxygen in an aqueous acid medium at an elevated temperature, at least twice the amount of molecular oxygen stoichiometrically required for the oxidation of the cobalt being used per gram atom of cobalt present in the oxoreaction mixture.
