The significantly higher oxidation stability of partially deuterated neopentyl polyol esters examined in this work appears to be the resultant product of two effects, viz., deuteration and the synergistic effect of alkali metal compounds with the antioxidant. The enhancement in oxidation stability attributable to deuteration 97 of the acid moiety of the ester appears to be 3 to 4-fold at 220 C. A similar degree of enhancement was obtained at Naval Air Development Center on 97 deuteration of a synthetic hydrocarbon. An additional enhanced lifetime of approx. 30-fold in the neopentyl polyol esters deuterated and non-deuterated appears to be due to an alkali metal effect.
