Substituted dihydro oxazines as hydrocarbon antioxidants

摘要

Hydrocarbon lube oil or hydrocarbon fuel for a combustion engine containing an amount of substituted dihydro oxazine sufficient to stabilize the hydrocarbon lube oil or hydrocarbon fuel against oxidative deterioration. A method for stabilizing either hydrocarbon lube oil or hydrocarbon fuel for a combustion engine against oxidative deterioration in which an oxidation stabilizing amount of substituted dihydro oxazine is added to the lube oil or the hydrocarbon fuel.
