Description

United States Patent IMPROVED MINERAL LUBRICATING OIL COMPOSITIUN No-Drawing. Application September 17, 1956 Serial No. 610,398
2 Claims. (Cl. 252--33.4)
This invention relates to new and improved lubricating compositions, and, more particularly, pertains to detergent mineral lubricating oil compositions havingincorporated therein'an additive capable of effectively reducing oil consumption as well as preventing or at least materially inhibiting wear and corrosion of metals with which these lubricating oil compositions come in contact;
It-iswell known that one of the best additive combinations forimproving the properties of lubricating oils particularly with respect to detergency is the combination of an.,oil-soluble sulfonate and an oil-soluble phenate. Although lubricating oils containing these two additives possess good detergent properties, they do not protect sufiiciently contacting metal surfaces against wear and corrosion; furthermore, these oils have the defect that their consumption during use are normally excessive. Various auxiliary agents, such as arylamines, e.g. phenylalpha-naphthylamine or phenolic compounds, such as alkyl phenols, have been used with sulfonates and/or phenates in an attempt to overcome some of their deficiencies, but, with little success.
Ithas now been discovered that lubricating oils containing minor amounts (e.g. from about 0.05% to about 15%, and preferably from about 0.1% to about 6% by weight) of an oil-soluble polyvalent metal sulfonate and of an oil-soluble polyvalent metal sulfur-free polyphenate can be greatly improved by reducing the depletion rate of the additives by reducing oil consumption, and by reducing wear as well as corrosion of contacting metal surfaces, these improvements being obtained by the addition to such lubricating oils a minor, but critical, amount of an oil-soluble straight or branched-chain saturated non-aromatic amine and/or amide having at least one aliphatic hydrocarbon radical containing from bout 12V to 30 carbon atoms, and preferably from 14 to 18 carbon atoms in the molecule; this aliphatic radical is preferably attached directly to a nitrogen atom of the amine or amide. The amount of amine which can be used in compositions of this invention can Vary from about 0.01% to about 0.2% by weight and preferably between 0.05 to 0.1% by weight.
The additives which impart the above desired properties Ito.the" lubricant oils described above may be de fined as oil-soluble straight or branched-chain saturated non-aromatic amines or amides and include oil-soluble long chain primary secondary or tertiary saturated aliphatic or cycloaliphatic mono or polyamines or amides having at least one alkyl radicaloffrom. 12 to 30 carbon atoms inthe molecule. Aliphatic monoamines of this typeinclude-mono di-, or tri-dodecyl, tetradecyl, hexadecylj-or. octadecyl monoamines. In the secondary and tertiary amines the alkyl'radicals can be the same or different. Aliphatic polyamines include alkyl substituted alkylene polyamines wherein the alkylene radical is from 2 to carbon atoms such as ethylene diamine, propylene .diamine, butylene diamine, diethylene tetraamine; tetraethylenepentamine and the alkyl substituent or substituent group(s) can be attached to the same or different nitrogen atoms in the molecule and should generally have from 12 to 18 carbon atoms. Such alkyl substituted alkylene polyamines include NC alkyl propylene diamine, N-lauryl propylene diamine and the like. Especially useful are the amines which are commercially available from Armour Chemical Company under the trade name of Armeens such as Armeen 18 which is a mixture of primary amines predominantly in octadecylamine or Armeen DM18 (dimethyloctadecylamine) or Duomeen C NHC H NH The amides include oil-soluble amides of aliphatic monoand polycarboxylic acids such as myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, soybean oil fatty acid, cocoanut oil fatty acid, succinic acid andmixtures thereof. Preferred amides are stearamide, cocoamide, N,N-dimethyl stearamide, N-lauryl stearamide and mixtures thereof.
Compositions of this invention may be prepared using" any lube oil. Mineral lubricating oils which are particularly desirable for use in compositions of this invention and which have been used as bases for the compositions of this invention are oils of the SAE SW, 10, 20, 30
5W-20, 5W-30 grades or higher grades obtained from West Texas Ellenburger. crudes, East Texas crudes, Oklahoma crudes, or California crudes.
Typical oils of this type are SAE SW and SAE 30 petroleum motor oils having the following properties:
The detergent salts which are used in compositions of this invention include sulfonates which can be oil-soluble neutral and/or basic polyvalent metal petroleum sulfonates, of which petroleum sulfonates of the metals of group II of the periodic table having an atomic number of from 12 to 56, inclusive are preferred, and especially of the alkaline earth metals. the neutral and/ or basic calcium, barium and magnesium petroleum sulfonates of oil-soluble petroleum sulfonic acids. The acids can range in molecular weight from about 350 to 550 and preferably are in the range of from 400 to 500. By basic petroleum sulfonates is meant that the amount of neutralizing agent, such as calcium carbonate and/or calcium hydroxide, which is used to neutralize the petroleum sulfonic acid, is in excess of that which is normally required to neutralize the acid. The excess should be from 10 to and preferably between 20 to 60 percent of that normally required to neutralize the acid.
The sulfur-free polyphenates used in compositions of thisinvention are oil-soluble neutral and/or basic polyvalent metal sulfur-free polyphenates. By sulfur-free polyphenate is meant to. include a plurality of phenolic radicals linked together through a carbon, such as where a plurality of simple phenates are condensed at positions ortho and/or para to the phenolic hydroxy group through alkylidine (methylene) radicals. The anionic portion ofthe molecule should contain only carbon, hydrogen and oxygenin the molecule. The cationic portion of the polphenate can be the same as that in the sulfonate and usually-will be, but different cations may be formaldehyde, acetaldehyde or benzaldehyde, e.g, calcium salt of octylphenol-formaldehyde condensation Patented Dec. 1, 1959:

Test conditions Wear 011 (Jonsumption Speed, r.p.m 1, 600 1, 800 Time, hrs 40 60 Load, p.s.i 83 75 Jacket temp., F 77 210 Oil temp., 11..- 85 M5 Comp. ratio 6 6 taining 0.4% SA Ca petroleum sulfonate, 0.3% SA Ca salt of octylphenol-formaldehyde condensation product and 0.2% by weight of phenyl-alpha-naphthylamine), Composition 4 (Mineral oil containing 0.3% SA Ca salt of octylphenol-formaldehyde condensation product and 0.1% Octadecylamine); Composition 5, (Mineral oil containing 0.1% SA Ca petroleum sulfonate and 0.3% SA preventing engine wear and reduction of oil consumption, 7
Ca salt of octylphenol-formaldehyde condensation product and 0.5% Octadecylamine), were tested under the above test conditions. With Compositions A, F and H wear reduction of over 50% over Composition 1 and above 50% to 75% over Compositions 2, 3, 4 and 5 was noted. Also with Compositions A, F and H, about 60% to reduction in oil consumption was noted whereas with compositions 2, 3, 4 and 5 no reduction in oil consumption was noted.
In addition to the addtives already described lubricating oil compositions contemplated herein may contain other agents, such as pour-point depressants, oiliness agents, blooming agents, compounds for enhancing the viscosity index of the lubricating oil, peptizing agents, etc.
This application is a continuation-in-part of our copending patent application Serial No. 366,560, filed June 7, 1953, now abandoned.
We claim as our invention:
1. A lubricating oil composition consisting essentially of a major amount of a mineral lubricating oil and containing from about 0.1% to about 6% by weight each of oil-soluble calcium petroleum sulfonate and oil-soluble calcium salt of sulfur-free octylphenol-formaldehyde condensation product and from about 0.01% to about 0.2% by Weight of an oil-soluble alkylamine selected from the group consisting of primary and secondary dodecylamine, tetra decylamine, hexadecylamine and Octadecylamine.
2. A lubricating oil composition consisting essentially of a major amount of a mineral lubricating oil containing from about 0.1% to about 6% by weight each of oil-soluble calcium petroleum sulfonate and oil-soluble calium salt of sulfur-free octylphenol-formaldehyde coudensation product and from about 0.05% to about 0.1% by weight of Octadecylamine.
