Abstract

3-Chlorobutanone-2 and butanone are prepared by bringing an n-butylene into intimate contact with an aqueous solution of cupric chloride and palladium chloride of pH below 3, containing 0.8-2 molecular proportions of copper and 0.005-0.05 molecular proportion of palladium per litre, at 95-180 DEG C., under superatmospheric pressure, while maintaining the oxidation potential of the solution by oxidation with oxygen (which may be as air or oxygen-enriched air) at a value above 330 mV (measured at 80 DEG C. against a standard saturated calomel electrode), removing the crude ketones from the solution after release of pressure and isolating them by further distillation, the chloride ions consumed being replaced in the solution, e.g. as hydrochloric acid. The treatment with oxygen may be carried out at the same time as reaction of the butylene, or periodically in the absence of the butylene after separarion of the crude ketones. The proportion of chlorobutanone in the product is raised by increasing (i) the reaction temperature, (ii) the Redox potential of the solution, and/or (iii) the copper content of the solution. The separation of pure chlorobutanone and butanone by distillation p procedures is described. Specifications 876,025 and 886,157 are referred
