HETEROCYCLIC NITROGEN COMPOSITION SELECTED AS ANTIOXIDANT/METAL DEACTIVATOR/ELECTRIC INSULATOR IN HYDROCARBON COMPOSITION

摘要

A hydrocarbon composition such as a lubricating or specialty oil containing a selected heteroaromatic nitrogen compound as an antioxidant/metal deactivator/electrical insulator having the following general formula: wherein each X is C or N with at least one X being N; Y is C or N; R is H or CH2NR'''2 where each R'' is H or alkyl of 1 to 20 carbons; R' is H, SR''' OR ''' or NR'''2 with each R''' being H or alkyl of 1 to 20 carbons.
