Abstract

Acetone peroxide and homologues thereof such as the peroxides of methyl ethyl ketone, di-ethyl ketone and di-isopropyl-ketone are prepared by a process which comprises reacting the ketone and hydrogen peroxide at low temperature in the presence of strong acids, characterized in that the hydrogen peroxide used in the reaction is not isolated as such, but is prepared by hydrolysis of persulphuric acid or a persulphate and the reaction with the ketone conducted in situ. The hydrolytic treatment is carried out in any manner known per se, such as by bringing the solution containing the acidified persulphate to an elevated temperature for a short time. Stabilizers such as urea may be present during the hydrolysis. If the peroxide is intended to be isolated in the free state it is extracted from the reaction mixture with a pure readily distillable solvent such as benzene or gasoline, but if it is intended to be used for improving the ignition quality of fuels for Diesel engines, gas oil is used as the extraction agent. In the latter case a 7 per cent solution of the peroxide in gas oil is prepared which is a readily dosable product. In an example a 13 per cent solution of H2S2O8 obtained by electrolysis of a 50 per cent solution of sulphuric acid is hydrolysed for 1 minute at 100 DEG C. After cooling to -20 DEG C. the theoretical amount of acetone calculated on the amount of active oxygen present is added slowly. The reaction mixture is stirred for 15 minutes and the peroxide extracted with gasoline.ALSO:The ignition quality of fuels for Diesel engines is improved by the addition of acetone peroxide or a homologue thereof, e.g. the peroxides of methyl-ethyl-ketone, diethyl ketone, and diisopropyl ketone. The peroxide is prepared by the direct action of the ketone on a hydrolyzed solution of persulphuric acid or a persulphate, and extraction by gas oil. A 7 per cent solution of the peroxide in gas oil is prepared as a readily dosable product.
