N-substituted triazole compounds

New triazole compounds, useful as metal deactivators and/or antioxidants in organic material, having the formula I: ##STR1## wherein X is the triazole residue of formula II: ##STR2## or the benzotriazole residue of formula III or IIIA: ##STR3## in which R is hydrogen or methyl.


I claim:
1. A triazole compound having the formula I ##STR13## wherein X is the benzotriazole residue of formula III or IIIA ##STR14## in which R is hydrogen or methyl.
2. A composition comprising a lubricant and an effective metal deactivating or antioxidant amount of at least one compound having the formula I, as defined in claim 1.
3. A composition according to claim 2 wherein the lubricant is a mineral oil or a synthetic oil.
4. A composition according to claim 3 wherein the lubricant is a mineral oil.
5. A composition according to claim 2 wherein 0.001 to 5.0% by weight of a compound of formula I is present, based on the weight of the lubricant.
6. A composition according to claim 5 wherein 0.02 to 1.0% by weight of a compound of formula I is present, based on the weight of the lubricant.
7. A composition according to claim 2 comprising one or more further additives known to improve the operating properties of the lubricant.
8. A composition according to claim 7 wherein the further additive is one or more of a further antioxidant, a further metal deactivator, a rust inhibitor, a viscosity-index improver, a pour-point depressant, a dispersant/surfactant and an anti-wear additive.
9. A composition according to claim 8 wherein the further additive comprises a phenolic or amine-type antioxidant.
10. A composition according to claim 9 wherein the further additive is diphenylamine, octylated diphenylamine, N-phenyl-1-naphthylamine or N-(octylated-phenyl)-1-naphthylamine.
