Methyl ethyl ketone and other aliphatic ketones

2 Methyl ethyl ketone and other aliphatic ketones 

Oxidation of methyl ethyl ketone at 100—145° C under pressure has been studied in detail [123], The intermediate products of this reaction are hydroperoxide and diacetyl, and the main oxidation products are acetic acid and ethyl acetate. The sequence of processes is 

Ethanol, methanol, acetone, methyl acetate, CO, and C02 are formed in small amounts. In the presence of Co and Ni acetates, methyl ethyl ketone is oxidized selectively to diacetyl at 80° C [124]. 

Oxidation of di-rc-propyl ketone (110—120° C) produces butyric and propionic acids in equimolar amounts [125,126], The sequence of reactions is suggested to be 

The products of methyl n-hexyl ketone oxidation are capronic and acetic acids, capronic aldehyde, and diketone (130°C) [126], The hydroperoxide formed by the oxidation of di-iso-propyl ketone is relatively stable [127]. Decay of hydroperoxide produces acetone and isobutyric acid
