For these purposes the compositions are Reactlens Showlllgthe Preparation of y generally screened by means of the well-known humidity be represented as follows!

' In Tween 81 RCOOH is oleic acid, N hasja value of '3 to 6, and accordingly, n n2 and 11 have values of l to 4 and may be the same or different. One skilled in the art will know that the anhydrization ofsorbitol in the above reaction is shown to involvethe hydrogen attached to the first carbon atom and the hydroxyl group on the 5th carbon atom. This reaction, as is known, may involve the hydrogen of the first carbon ,atOmof the sorbitol molecule and the hydroxyl group'of the fourth carbon atom in which event an ether ring having five carbon atoms results and the subsequentrea'ction with fatty acid and ethylene oxide resultsina product having the following formula: r
.. Compounds of both Formula I and Formula II are contemplated by this invention and'in fact are present as a complex mixture in the product known as' Tween 81. Increases 'in the amountsof ethylene oxide used in the reaction to the point where vN has a value of 7 to results in a product known as Tween 80 which for purposes of this invention is equivalent to Tween 81, being also polyoxyethylene sorbitan monoleate. Tween 80" has the same corrosion-inhibiting properties as Tween 81 as far as the purposes of this invention are concerned. These products are generally used to form emulsions, their respective abilities in this, regard, as measured by the interfacial surface tensions in dynes at C., being equivalent at concentrations of 0.1 weight percent and varying at lesser and greater'concentrations.
Tween 80 has an HLB factor of 15.0.and'is an oily liquid, having a viscosity (cp. at 25 C.) of 350-550,
a fsp.'gr. of 1.06-1.10, flash point 605 F., fire point of 645 F. and is a lemon-yellow color. The chemical name of polyoxyethylene sorbitan monoleate will be used in the balance of the specification and claims to mean either or both Tween 80 and Tween 81" and mixtures of same having either a 4 carbon atoms ether ring, ora 5 carbon atom ether ring, or both, as indicated heretofore. Although the invention will be demonstrated by reference to experiments using Tween 81 the invention will apply to polyoxyethylene sorbitan fatty esters broadly, regardless of the number of ethylene oxide groups reacted with each molecule of the ether-ester.
Accordingly, a primary object of this invention is to provide a lubricating composition which meets the requirements of the static water-drop corrosiontest MIL-v P-17272 (SHIPS), July 18, 1952. 7
Another object of the invention is to provide a lubricating composition which meets the engine performance requirements of M.S. 9030 oil (MIL-L-9000A), and also 7 the static water-drop test, by including in said composition a minor proportion of,v polyoxyethylene sorbitan ester of a fatty acid, particularly the. monoleate ester.
Other objects and advantages of the invention will become apparent as the description thereof proceeds.
To demonstrate the invention, a numberof known rust inhibitors were tested in a base mineral oil composition fortified with a detergent-inhibitor and a commercial corrosion inhibitor. The base or blankoil consisted of:
92.0 weight percent intermediate V.I. oil (200 vis.
neutral).
5.4 weight percent of a detergent inhibitor consisting of a mixture of 3.44 weight percent mineral lubricating oil, 1.35 wt. percent of barium diisobutyl phenol sulfide and 0.61 wt. percent of calcium petroleum sulfonate.
2.6 weight percent zinc hexyl dithiophosphate.
This base mineral oil composition so fortified meets the US. Navy engine performance requirements of M.S. 9030 oil (MIL-L-9000A) using a GM 71 engine. The zinc hexyl dithiophosphate is a commercial corrosion inhibitor which in itself or in combination with the detergent-inhibitor does not pass the static Water-drop corrosion test, but is used to meet the other anti-corrosion properties necessary to qualify the base composition to meet the M.S. 9030 oil requirements, which tests include bearing corrosion tests, etc. These addends are subsequently further defined.
The results of these experiments are set forth in the following table wherein blend No. 1 is the base oil just described.

1 Specimen was stained with surface disturbed. 2 Specimen was stained with no surface disturbances.
An M.S. 9030 oil should show no rust at the end of 96 hours testing. In addition, an M.S. 9030 oil must have a viscosity at 210 F. of 58 to 70 SUS, a flash point of about 390 F. minimum, and a maximum pour point of about 10 F. The procedure in MIL-1 47272 (SHIPS), July 18, 1952, comprises subjecting a io -inchthick, cold-rolled, steel sheet (SAE 1020) specimen shaped as an equilateral triangle to dimpling at its center to a depth of 0.110 inch. The dimple side is thoroughly polished with fine sand paper, and cleaned with C.P. benzene and petroleum ether. After cleaning, the specimen is'quickly immersed in the'oil sample with the concave side of the dimple uppermost. The container contai ing the test oil and specimen is then placed in an oven at l40i2 F. for one hour. After this, the container and contents are removed from the oven and a drop of water (0.2 ml.) is placed in the oil so as to rest in the shallow depression or dimple in the steel specimen by using a clean hypodermic syringe. The container is then covered with a glass cover, stored in the oven at 140:2" F., and observed daily for signs of failure, that is, the first sign of rust which definitely increases in intensity on the next day.
fied by other addends or not, through the static waterdrop corrosion test. The preferred compounds for this purpose are the monoleate esters which are known as Tween 80 and Tween 81, the latter compound being used to demonstrate the invention by blend No. 14.
The amount of the sorbitan derivativesused may vary somewhat within the prescribed limits depending on the overall composition and the oxidation-detergent or other addends present therein. In general, about 0.2 to'0.40 weight percent of polyoxyethylene sorbitan monoleate has been found to satisfactorily carry the composition through this severe rust test. About 0.2 weight percent is the minimum that will give assured protection and quantities over about 0.40 do not show any detectable decrease in the degree of staining.
The oil compositions intended by this invention may inclued other addends such as thickeners, V.I. improvers, oiliness agents, pour-point depressants, other anti-oxidants and other well-known types of addends, or may comprise a mineral lubricating oil and the polyoxythylene sorbitan monoleates alone in the amounts specified. Although this invention is limited to compositions passing the static Water-drop corrosion test designated as MIL- P-l7272 (SHIPS), it is not limited to the type of oil used in the experiments. Any mineral lubricating oil may be used whether obtained from Mid-Continent, Pennsylvania Coastal, or Texas crudes. The lubricating oil may be a light or heavy oil of the solvent-refined or conventionally-refined variety. The invention should be distinguished from the prior art which shows the use of sorbitan monoleate as a corrosion inhibitor in oils by means of the humidity cabinet test, or other tests using a corrosive atmosphere of a haloacid, since there is no relationship or correlation between compositions which pass the cabinet test and the problem confronting one in relation to the critical static water-drop corrosion test, a particularly difficult species of corrosion test. Other specific examples of compositions of this invention are set forth in the following table:
TABLE II Composition (Wt. percent) Constituent Blend No 16 14 17 Mineral llubricating oil (200 vis.
The detergent-inhibitor used in the compositions of this invention are described in United States Patent 2,379,241 by McNab and U.S. Patent 2,761,845 by Rogers. Broadly, this addend may comprise an oil-soluble metal salt having the general formula,
where M is a metal, preferably a divalent metal, cobalt, barium, calcium, aluminum, zinc, magnesium, cadmium, tin, lead, chromium, manganese and nickel; Y is a member of the right-hand side of group VI of the periodic table of elements, as oxygen or a member of the sulfur family; Ar is an aromatic nucleus such as benzene, or a condensed ring nucleus such as naphthalene, anthracene, etc.; Z is sulfur, selenium or tellurium; x is an integer of from 1 to 5, preferably 1 or 2; Q is an organic group which may be identical with the part of the com, pound which is on the left side of Z, or a group having a somewhat similar type of structure, or it may be a hydrocarbon group such as amyl, octadecyl, or aralkyl as benzyl, or aryl as tolyl; and R represents one or more hydrocarbon groups such as alkyl, or alkenyl, e.g., amyl, octyl, octenyl, etc., or cycle-aliphatic, e.g., cyclohexyl. Examples are the cobalt or barium salts of hydroxy tertiary-amyl phenyl sulfide, and the cobalt or barium salts of hydroxy diisobutyl phenyl sulfide. In place of the calcium petroleum sulfonate, any oil-soluble metal salt of an acidic organic compound may be used, i.e., the mixed aluminum-calcium soap of acids obtained in the oxidation of sweater oil, or nickel oleate. In general, from about 0.01 to 6.5 weight percent of the finished addend containing about 63.75 wt. percent of a mineral lubricating oil, 25.0% of the barium salt and about 11.25% of the calcium petroleum sulfonate is used. A species of this addend sold under the trade name of Paranox 65, has the following properties:
' The zinc hexyl dithiophosphate may be replaced with I other commercial addends designed for this purpose, such as zinc or cadmium alkyl dithiophosphates including zinc heptyl dithiophosphate, cadmium heptyl dithiophosphate, zinc octyl dithiophosphate, cadmium octyl dithiophosphate, etc.
What is claimed is:
1.
