Abstract

Aldehydes and ketones are produced by contacting hydrocarbons which contain olefinic bonds with an aqueous solution of a compound of a metal of the platinum group at a temperature in the range 0 DEG C.-250 DEG C., whereby an aldehyde or ketone having the same number of carbon atoms as the initial hydrocarbon is obtained. Suitable metallic compounds are: palladium chloride, hexachloroplatinic acid, rhodium chloride, and palladium phosphate. The aqueous solution preferably contains free hydrochloric, sulphuric or phosphoric acid. The hydrocarbon may be brought into intimate contact with the aqueous solution by means of a spray-tower, packed column, or stirring-vessel. In order to increase the miscibility, a solvent, such as glacial acetic acid or dioxane, may be added. In Example (1), propylene is irrigated in a spray-tower at 80 DEG C. under a pressure of 80 atm. with an aqueous solution which contains 17.8 grm. PdCl2 and 55 grm. HCl per litre. The effluent solution is distilled in a column; and acetone is obtained as distillate. The aqueous solution, which now contains precipitated palladium, is pumped from the still to a second spray-tower, in which it is contacted with oxygen at 80 DEG C. and a pressure of 50 atm. The clear solution so obtained is re-used for irrigating propylene. The velocity of circulation of the solution is adjusted so that the solution remains in the spray-towers for 15 minutes. Examples 5 and 8 relate to the preparation of acetaldehyde by the action of an aqueous solution of palladium chloride and of rhodium chloride, respectively, on ethylene. Example 6 relates to the production of acetophenone from styrene. Examples 3, 7 and 9 relate to the production of n-octyl-methyl ketone, benzyl-methyl-ketone, cyclopentanone, b -indanone, pentene-2-al-1, crotonaldehyde, cyclohexanone, and methyl-ethyl ketone.
