Oil compositions containing anti-wear additives

摘要: Liquid hydrocarbon oils (including lubricants and fuels) have added thereto a minor amount of an additive mixture dimer linoleic acid glycol or diamine, the comprising 0.8-1.2 moles diamine per mole dimer. Typical glycols are ethylene glycol, 1,4-butane diol 3,6,9-trioxa-1,4,7,10-tetramethyl undecane-1,11-diol, others being mentioned, typical diamines 1,12-dodecene 1,9-heptadecene diamine. The may be present in monomer, trimer. Suitable specified, following optional additives referred to:- phenothiazine, phenyl - alpha naphthylamine, lecithin, petroleum sulphonates, sorbitan monooleate, barium salt isononyl phenol sulphide, vinyl acetate/fumaric coconut alcohol ester copolymers polymethacrylates. Also described oil concentrates containing up to 30 weight cent mixture.
