| titleOfInvention | Improvements in lubricating oil compositions |
| abstract | An extreme pressure lubricating composition comprises a major proportion of lubricating oil, a minor proportion of a halogen- and phosphorus-bearing aliphatic compound and a minor proportion of a separate thionic material. The thionic material is either an organic sulphur compound or elemental sulphur. Lubricating oils mentioned include mineral, animal, vegetable, synthetic, hydrogenated and voltolized oils. Halogen- and phosphorus-bearing aliphatic compounds which may be employed include halogen- and phosphorus-bearing aliphatic hydrocarbons and halogen- and phosphorus-bearing aliphatic compounds containing oxygen in the molecule and particularly halogenated phosphorus-bearing aliphatic compounds. Substances specifically mentioned are chlorlauryl phosphine, chlor-octyl phosphine, chlor-di-ethyl di-thiophosphine sulphide, chlor-butyl phosphate, chlor-lauryl thiophosphate, chlor-lauryl thiophosphite and chlor-aliphatic phosphites such as chloramyl phosphite and chlor-lauryl phosphite. The organic sulphur compound employed as the thionic material may be an aliphatic material and it may be an ester. Organic sulphur compounds mentioned include sulphurized methyl linoleate, sulphurized methyl oleate, sulphurized methyl aryl-substituted linoleate, sulphurized animal and vegetable fatty oils, diphenyl sulphide, dibenzyl sulphide, di-p-tolyl sulphide, diphenyl disulphide, dibenzyl disulphide, di-p-tolyl disulphide, diphenol disulphide, diphenyl sulphone, di-p-tolyl sulphone, amyl sulphone, diphenyl sulphoxide, di-p-tolyl sulphoxide, diphenyl thio-urea, o-tolyl thio-urea, naphtha xanthate, thiocarbamylamine, butyl sulphide, butyl disulphide, amyl sulphide, amyl disulphide, p-cresyl ethyl thio ether, dithio diglycol, ethyl dithio oxalate, heptyl sulphide, thioketones, thiophenes and thiophanes. Specification 665,105 is referred to. The Specification as open to inspection under Sect. 91, refers to a lubricating composition comprising a major proportion of lubricating oil, a minor proportion of a halogen- and phosphorus-bearing compound and a minor proportion of a thionic material. Lists of halogen- and phosphorus-bearing compounds (including cyclic compounds) and of thionic materials are given. In examples, mineral lubricating oil compositions are described containing (1) chloroamyl phosphite and sulphurized methyl linoleate, (2) methyl phosphonic chloride and sulphurized methyl oleate, (3) o-chlorphenyl phosphine and dibenzyl disulphide, (4) o-chloro-triphenyl phosphine oxide and diphenyl sulphide, (5) phosphazo-chloro-benzene chloride and butyl disulphide, (6) sulpho-phosphazobenzene chloride and benzyl thiocyanate and (7) chloropentamethylene phenylphosphine and dibenzyl disulphide. This subject-matter does not appear in the Specification as accepted. |
