    摘要: The present invention relates to industrial gear lubricating compositions that include a specific class of substituted triazoles, where the substituted triazole includes at least one hydrocarbyl group linked to one of the nitrogen atoms in the triazole ring. Such compositions provide surprisingly good seal compatibility compared to compositions with other triazoles and/or alternative additives.

    摘要: A lubricant composition that is particularly suited for use in steam and gas turbine oils and in circulating oils has a balance of excellent oxidative stability and reduced sludge formation and comprises a blended mixture of alkylated phenyl-α-naphthylamine and at least oil soluble triazole or triazole derivative in an oil of lubricating viscosity, such compositions being capable of a residual RPVOT of 25% after at least 500 hours test duration test duration 120° C. in Dry TOST test or, alternatively 50% after 700 hours or 25% after 1000 hours.
