Abstract
The invention comprises a process for the production of an aliphatic ketone by the reduction of an aliphatic 1,3-keto-alcohol containing from 4 to 6 carbon atoms with hydrogen at a partial pressure in the range 1-100 atmospheres and at a temperature in the range 100-200 DEG C. in the presence of a catalyst having a dehydrating and a hydrogenating effect. In a modification adapted as a continuous process the catalyst is suspended in the ketone and hydrogen is passed through the suspension. The reaction apparatus used to carry out the Fischer-Tropsch synthesis may, for example, be used in this modification, in which it is advantageous to use an excess of hydrogen which, after separation of the water and ketone vapours evolved in the reaction from it, can be recycled. It is also advantageous to add a quantity of the keto-alcohol which is substantially equivalent to the ketone and water which distills off from the suspension, continuously to the suspension. The catalyst advantageously consists of mixed metal oxides such as copper oxide-chromium oxide or zinc oxide-chromium oxide or of dehydrating and hydrogenation catalysts, such as, on the one hand, aluminium oxide, silica gel, or pumice and, on the other hand, nickel catalysts. The catalyst may be used as a stationary or fixed bed, e.g. it may be disposed in the tubes of a pipe or tube reactor or the reactor may be lined with catalytic materials. In examples: (1) methyl ethyl ketone is prepared from 3-keto butanol-1 in the presence of copper-chromite at 150-160 DEG C., the pressure being 40 atmospheres guage at the beginning of the reaction and 18.7 atmospheres gauge at the end; (2) methyl-isopropyl ketone is prepared from 2-methyl-3-keto-butanol-1 under similar conditions.
