A process for oxidizing liquid hydrocarbon comprising blowing an oxidizing gas through the liquid mass of said hydrocarbon in the presence of an amine oxide of the formula:
- R.sub.1 R.sub.2 R.sub.3 N.fwdarw.O
- wherein R.sub.1 is an alkyl radical having from 10 to 18 carbon atoms or an amide substituted group of the formula:
- ##STR5## wherein RCO is a long chain alkanoyl radical and n is a small whole number;
- and R.sub.2 and R.sub.3 are selected from the group consisting of alkyl radicals equivalent to R.sub.1, lower alkyl radicals of 1 to 9 carbon atoms, and hydroxyalkyl groups.
