The present study indicated the liquid phase air oxidation of technical n-paraffins (C12C14), as a raw material, using dehydrated boric acids catalyst with an effective co-catalyst to give secondary alcohols with high selectivity.
This catalyst system consists of dehydrated boric acids with a highly degree of dispersion property, and ammoniac base co-catalyst.
This system prevents the inhibitory effect of aromatic compounds in n-paraffins on oxidation.
Present boroxine (metaboric acid ester of alcohol) retards the auto-oxidation of n-paraffins, but the ammoniac base co-catalysts lessen this effect. Thus, we have been able to employ adequate dehydrated boric acids.
The authors have thus devised a highly selective oxidation method of n-paraffins to secondary alcohols.
Clarification of the ammoniac base co-catalyst should be further studied for catalysis mechanisms.
