Definitions
- Antioxidants which have been used, for example, 'incl-ude: phenolic-type compounds, particularly alkylated phenols, such as 2,6-di-tertiary-butyl-4-methyl phenol, 2,4,6-tri-tertiary-butyl-phenol and the like; aryl amines, such as phenyl-alpha-naphthyl amine, butyl-alpha-naphthyl amine, etc.; and alkylated diphenyl amines, such as octyldiphenyl amine.
- anti-rust agents have been utilized in turbine oils.
- One class of such anti-rust agents are theproducts produced by first reacting a monocarboxylic acid with a polyalkylenepolyamine and then reacting the product so formed with an alkenyl succinic acid anhydride.
- This class of anti-rust agents and their manner ofpreparation are fully described in U.S. Patent No. 2,568,876, issued September 25, 1951, to R. V. White et al. As shown in that patent, the monocarboxylic acid is reacted With the polyalkylenepolyamine in a mole proportion varying between about 1 and about x-l to 1,
- alkenyl succinic acid anhydride is then reacted with the intermediate product in a molar proportion varying between about x1 and about 1 to 1, respectively; the sum of the number of moles of the monocarboxylic acid and of the alkenyl succinic acid anhydride reacted with each 'tinued under these conditions for three hours. .ti'o'n product had an N.N. of 56.6.
- the above object is weight, of theactive anti-rust accomplished by the addition to the turbine oil of a small mole of the polyalkylenepolyamine being no greater than x.
- a specific product of this type is one prepared from oleic acid, triethylenetetramine and tetrapropenyl succinic acid anhydride, the preparation of which is' illustrated by the following example.
- tris-(2-chloropropyl)-thionophosphate has not been proposed heretofore as an extreme pressure agent for lubricating oils. Accordingly, it is considered that the present invention embraces the use Reissued July 4, 1961 of this material as an extreme pressure agent, not only in turbine oils, but in lubricating oils in general.
- the ability of tris-(Z-chloropropyl)-thionophosphate as an extreme pressure additive and particularly its unique ability as an extreme pressure additive for use in turbine oils in comparison with a number of compounds heretofore recognized in the art as extreme pressure additives is illustrated by the data presented in Table I.
- This table shows the results of antioxidant, anti-rust and extreme pressure tests conducted on a typical turbine oil composition containing the usual amounts of antioxidant and anti-rust additives and on this same turbine oil composition having added thereto (a) diiferent known extreme
- the amount of tris-(Z-chloropropyl)-thionophosphate to be used as an extreme pressure agent in lubricating oils, including oxidation and rust-inhibited turbine oils, will range generally from about 0.25% to about 5.0%, the usual amount being from 1.0% to about 3.0%.
- Turbine oils in which the tris-(2-chloropropy1)-thionophosphate is employed may suitably contain from about 0.05 to about 2.0%, by weight, of antioxidant and from about 0.01% to about 1%, by weight, of anti-rust agent.
- oil compositions contemplated herein may also contain minor amounts of other additives, designed to improve the properties thereof in other respects, such as V.I. improvers, pour depressants, defoamants, etc.
- the turbine oil used as the base oil in all of the tests was a 400" SUV at 100 F., solvent-refined Mid-Continent oil containing 0.25% of 2,6-ditertiary butyl paracresol, a commercial antioxidant additive and 0.1% of an anti-rust agent prepared from oleic acid, triethylenetetramine and tetrapropenyl succinic acid anhydride after the fashion of Example I, hereinabove.
- a method of lubricating a marine turbine and the associated reduction gears which comprises applying to the relatively moving parts thereof a composition comprising a major proportion of mineral lubricating oil, a minor proportion, from about 0.05% to about 2%, by weight, of a phenolic antioxidant, a minor proportion, from about 0.01% to about 1%, by weight, of an antirust agent consisting of a reaction product obtained by reacting a monocarboxylic acid with a polyalkylenepolyamine having one more nitrogen atom per molecule than there are alkylene groups in the molecule, in a molar proportion varying between about 1 and about x-l to 1, respectively, wherein x represents the number of nitrogen atoms in the polyalkylenepolyamine molecule, to produce an intermediate product, and reacting an alkenyl succinic acid anhydride with said intermediate product, in a molar proportion varying between about x-l and about 1 to 1, respectively; the sum of the number of moles of said monocarboxylic acid
- a method of lubricating a marine turbine and the associated reduction gears which comprises applying to the relatively moving parts thereof a composition comprising a major proportion of mineral lubricating oil, a minor proportion, from about 0.05 to about 2%, by weight, of a 2,6-ditertiary butyl paracresol, a minor proportion, from about 0.01% to about 1%, by weight, of a reaction product formed by reacting about one and one-third molar proportions of oleic acid with 1 molar proportion of triethylenetetramine to rform an intermediate product and then reacting about 1 molar proportion of the intermediate product with 2 molar proportions of tetrapropenyl succinic acid anhydride and a minor proportion, from about 0.25% to about 5%, by weight, of tn's-(2-ch1oropropy1)-thionophosphate.
