Abstract
Abstract A composition comprising (A) a mixed metal salt of (A)(I) at least one acid of formula I <IMAGE> I wherein R' and R2 are the same or different and each of R' and R2 is a hydrocarbon-based radical, and (A)(II) at least one aliphatic or alicyclic carboxylic acid containing from about 2 to about 40 carbon atoms; the ratio of equivalents of (A)(I) to (A)(II) being in the range of about 0.5:1 and about 400:1; and (B) at least one sulfurized Group II metal phenate; the weight ratio of (A) to (B) being in the range of about 40:1 to about 1:2. These compositions are useful in lubricants and functional fluids (such as hydraulic fluids) as antioxidants and extreme pressure agents having improved thermal stability.
