Definitions
- This invention relates to lubricants based on hydrorefined lubricating oils, and, more particularly, to multipurpose industrial oils for use in gear, hydraulic and other specialty applications.
- the invention relates to lubricating compositions comprising a major amount of a hydrorefined mineral lubricating oil and a minor amount of the combination of an aliphatic olefinic compound and a sulfurized olefinic hydrocarbon.
- lubricant base oil stocks have been described in the prior art for preparing lubricating compositions. These include natural as well as synthetic oils. Natural oils include liquid pertroleum oils and solvent-treated or acid-treated mineral oils of the paraffinic, naphthenic and mixed paraffinic-naphthenic types. Oils of lubricating viscosity derived from coal or shale also are useful base oils. More recently, lubricant based stocks prepared by a hydrorefining process have been suggested as having advantages over solvent-extracted oils because the hydrorefining process is capable of producing new types of oils having modified structural and improved viscosimetric properties.
- a new lubricating composition which comprises a major amount of (A) a hydrorefined lubricating oil, and a minor amount of the combination of: (B) at least one aliphatic olefinic compound and (C) the sulfurization product of at least one aliphatic, aryl aliphatic or alicyclic olefinic hydrocarbon containing from about 3 to 30 carbon atoms.
- the aliphatic olefinic compound is at least one unsaturated fatty acid or fatty acid ester containing olefinic unsaturation in the acid moiety and the weight ratio of component B to component C is no greater than 1:1.
- Such lubricant compositions derived from hydrorefined oils exhibit improved clarity, stability, extreme pressure properties, anti-wear capabilities and reduced staining of copper parts.
- compositions of the invention which are described more fully below comprise at least three components:
- Component (B) is at least one aliphatic olefinic compound and Component (C) is the sulfurization product of at least one aliphatic, aryl aliphatic or alicyclic olefinic hydrocarbon containing from about 3 to 30 carbon atoms.
- Component (A) in the compositions of the invention is a hydrorefined lubricating oil.
- Hydrorefining is a process for treating various oil stocks wherein an oil stock feed is combined with hydrogen and passed over a catalyst at elevated temperature and pressure. The extent of the treatment depends on the type of feedstock, the type of catalyst and the treating conditions. In the process, the hydrogen reacts with sulfur-containing compounds in the oil to form hydrogen sulfide and saturated hydrocarbons. The hydrogen also reacts with nitrogen-bearing compounds in the oil to form ammonia.
- hydrorefining is particularly useful for crude oils containing undesirable amounts of sulfur and nitrogen. Hydrorefining of oil feedstocks also results in improved color, neutralization, and some reduction in carbon residue.
- Hydrorefining can be classified into two types depending on the desired results and intended use.
- the hydrorefined stock may be used as feedstock for subsequent further processing, or the hydrotreated stock may be used as a base or blending stock for finished lubricants.
- Hydrorefined oils of various types and viscosities are available from a variety of commercial sources since the process is used by most of the major oil refiners. Hydrorefined oil is desirable because of the reduction in undesirable sulfur and nitrogen content, improved color, improved stability and the relatively higher viscosity and natural viscosity index exhibited by such oils as compared to solvent refined oils.
- One of the difficulties in using hydrorefined oil is that many chemical additives normally used in lubricating oils are not compatible with the hydrorefined oils and thus cannot be used.
- oils are available from Gulf Canada under the general trade designation Paraflex. Particular oils are identified according to the ISO viscosity number which corresponds to the viscosity of the oil in centistokes at 40°C. Examples of such oils include Paraflex 10, Paraflex 100, Paraflex 460 (bright stock) and Paraflex 1000 (cylinder stock).
- Component B in the compositions of the invention is at least one aliphatic olefinic compound which generally will contain at least about 8 carbon atoms and preferably between about 8 and 30 carbon atoms.
- the aliphatic olefinic compound useful as component B in the compositions of the invention may be an olefinic hydrocarbon such as 1-octene, 1-decene, 1-tetradecene, 1-octadecene, 1-eicosene, etc.
- Aliphatic olefinic compounds containing internal double bonds also are useful as component B, and examples of such olefins include 2-decene, 5-decene, 9-octadecene, etc.
- the a-olefins are preferred, especially those containing from 12 to 20 carbon atoms. Mixtures of these olefins are available commercially, and such mixtures are contemplated for use in this invention.
- Component B is preferably a fatty acid, a fatty acid ester, or mixtures thereof.
- fatty acid refers to acids which may be obtained by hydrolysis of naturally occurring vegetable or animal fats or oils. These fatty acids usually contain from 16 to 20 carbon atoms and are mixtures of saturated and unsaturated fatty acids.
- the unsaturated fatty acids generally contained in the naturally occurring vegetable or animal fats and oils may contain one or more double bonds and such acids include palmitoleic acid, oleic acid, linoleic acid, linolenic acid, petroselenic acid, erucic acid, gadoleic acid, vaccenic acid, ricinoleic acid and minor amounts of compounds containing more than 20 carbon atoms such as behenic acid.
- the unsaturated fatty acids useful as component B may comprise mixtures of acids such as those obtained from tall oil or by the hydrolysis of peanut oil, soybean oil, cottonseed oil, sunflower seed oil, or wheat germ oil.
- Tall oil is a mixture of rosin acids, mainly abietic acid, and unsaturated fatty acids, mainly oleic and linoleic acids.
- Tall oil is a by-product of the sulfate process for the manufacture of wood pulp.
- the most preferred aliphatic olefinic compounds useful as component B in the compositions of the invention are fatty acid esters which contain olefinic unsaturation in the fatty acid moiety.
- the most particularly preferred are the fatty oils, that is, naturally occurring esters of glycerol with the fatty acids described above, and synthetic esters of similar structure.
- naturally occurring fats and oils containing unsaturation include animal fats such as neat's-foot oil, lard oil, depot fat, beef tallow, etc.
- Naturally occurring vegetable oils useful as component B include cottonseed oil, corn oil, poppy-seed oil, safflower oil, sesame oil, soybean oil, sunflower seed oil and wheat germ oil.
- the fatty acid esters which are useful as component B in the invention also may be prepared from aliphatic olefinic acids of the type described above such as oleic acid, linoleic acid, linolenic acid, and behenic acid by reaction with alcohols and polyols.
- aliphatic alcohols which may be reacted with the above-identified acids include monohydric alcohols such as methanol, ethanol, n-propanol, isopropanol, the butanols, etc.; and polyhydric alcohols including ethylene glycol, propylene glycol, trimethylene glycol, neopentyl glycol, glycerol, etc..
- Component C in the compositions of this invention is a sulfurization product of at least one aliphatic, arylaliphatic or alicyclic olefinic hydrocarbon compound containing about 3-30 carbon atoms.
- R 1 , R 2 , R 3 , and R 4 may also together form an alkylene or substituted alkylene group; i.e., the olefinic compound may be alicyclic.
- substituents in the substituted moieties described above is not normally a critical aspect of the invention and any such substituent is useful so long as it is or can be made compatible with lubricating environments and does not interfere under the contemplated reaction conditions.
- substituted compounds which are so unstable as to deleteriously decompose under the reaction conditions employed are not contemplated.
- certain substituents such as keto or aldehydo can desirably undergo sulfurization.
- the selection of suitable substituents is within the skill of the art or may be established through routine testing.
- substituents include any of the above-listed moieties as well as hydroxy, carboxy, carbalkoxy, amidine, amino, sulfonyl, sulfinyl, sulfonate, nitro, phosphate, phosphite, alkali metal mercapto and the like.
- the olefinic compound is usually one in which each R group which is not hydrogen is independently alkyl or alkenyl, or (less often) a corresponding substituted radical.
- Monoolefinic and diolefinic compounds, particularly the former, are preferred, and especially terminal monoolefinic hydrocarbons; that is, those compounds in which R 3 and R 4 are hydrogen and R 1 and R 2 are alkyl (that is, the olefin is aliphatic).
- Olefinic compounds having about 3-30 and especially about 3-20 carbon atoms are particularly desirable.
- the olefinic compound also can be an arylaliphatic compound, particularly wherein the aryl group is a phenyl or substituted phenyl group.
- aryl group is a phenyl or substituted phenyl group.
- Specific examples include styrene, a-methyl styrene, vinyl toluene, 4-ethyl vinyl benzene, etc.
- Propylene, isobutene and their dimers, trimers and tetramers, and mixtures thereof are especially preferred olefinic compounds.
- isobutene and diisobutene are particularly desirable because of their availability and the particularly high sulfur-containing compositions which can be prepared therefrom.
- the sulfurizing reagent used for the preparation of component C may be, for example, sulfur, a sulfur halide such as sulfur monochloride or sulfur dichloride, a mixture of hydrogen sulfide and sulfur or sulfur dioxide, or the like. Sulfur-hydrogen sulfide mixtures are often preferred and are frequently referred to hereinafter. However, it will be understood that other sulfurization agents may, when appropriate, be substituted therefor.
- the amounts of sulfur and hydrogen sulfide per mole of olefinic compound are, respectively, usually about 0.3-3.0 gram-atoms and about 0.1-1.5 moles.
- the preferred ranges are about 0.5-2.0 gram-atoms and about 0.4-1.25 moles respectively, and the most desirable ranges are about 0.8-1.8 gram-atoms and about 0.4-0.8 mole respectively.
- the temperature range in which the sulfurization reaction is carried out is generally about 50-350°C.
- the preferred range is about 100-200°C., with about 125-180°C. being especially suitable.
- the reaction is often preferably conducted under superatmospheric pressure; this may be and usually is autogenous pressure (i.e., the pressure which naturally develops during the course of the reaction) but may also be externally applied pressure.
- autogenous pressure i.e., the pressure which naturally develops during the course of the reaction
- the exact pressure developed during the reaction is dependent upon such factors as the design and operation of the system, the reaction temperature, and the vapor pressure of the reactants and products and it may vary during the course of the reaction.
- materials useful as sulfurization catalysts may be acidic, basic or neutral, but are preferably basic materials, especially nitrogen bases including ammonia and amines.
- the amount of catalyst used is generally about 0.05-2.0% of the weight of the olefinic compound. In the case of the preferred ammonia and amine catalysts, about 0.0005-0.5 mole per mole of olefin is preferred, and about 0.001-0.1 mole is especially desirable.
- a further optional step in the preparation of component C is the treatment of the sulfurized product, obtained as described hereinabove, to reduce active sulfur.
- An illustrative method is treatment with an alkali metal sulfide as described in U.S. Patent 3,498,915.
- Other optional treatments may be employed to remove insoluble by-products and improve such qualities as the odor, color and staining characteristics of the sulfurized compositions.
- Sulfur (629 parts, 19.6 moles) is charged to a jacketed high-pressure reactor which is fitted with an agitator and internal cooling coils. Refrigerated brine is circulated through the coils to cool the reactor prior to the introduction of the gaseous reactants. After sealing the reactor, evacuating to about 6 torr and cooling, 1100 parts (19.6 moles) of isobutene, 334 parts (9.8 moles) of hydrogen sulfide and 7 parts of n-butylamine are charged to the reactor. The reactor is heated using steam in the external jacket, to a temperature of about 171°C. over about 1.5 hours. A maximum pressure of 720 psig. is reached at about 138°C. during this heat-up.
- the pressure Prior to reaching the peak reaction temperature, the pressure starts to decrease and continues to decrease steadily as the gaseous reactants are consumed. After about 4.75 hours at about 171°C., the unreacted hydrogen sulfide and isobutene are vented to a recovery system. After the pressure in the reactor has decreased to atmospheric, the sulfurized mixture is recovered as a liquid.
- the sulfurizing agent may be sulfur, and the reaction is effected by heating the olefinic compound with sulfur at a temperature of from 100-250°C., usually about l50-2l0°C. with efficient agitation and in an inert atmosphere (e.g., nitrogen).
- the weight ratio of olefin to sulfur may be as high as 15:1 and is generally between about 5:1 and 10:1.
- reaction mixture consist entirely of the olefin and sulfur
- reaction may be effected in the presence of an inert solvent such as alcohol, ether, ester, aliphatic hydrocarbon or halogenated aromatic hydrocarbon which is a liquid at the reaction temperatures employed.
- insoluble by-products may be removed by filtration, usually at an elevated temperature (about 80-120°C.).
- the filtrate is the desired sulfurized product.
- compositions of this invention typically contain components B and C in a weight ratio no greater than 1:1.
- the weight ratio of component B to component C is from about 0.2:1 to about 1:1, and more preferably, from about 0.2:1 to about 0.5:1.
- the following examples are illustrative of combinations of components B and C which are useful in the invention.
- the lubricating compositions of this invention comprise a major amount of component A and a minor amount, generally from about 0.01 to 20% and preferably from about 0.01 to 10%, by weight of component A of the combination of components B and C.
- the lubricating compositions of the invention may be prepared merely by blending the oil and the components, or the components may be diluted in substantially inert diluents and thereafter blended with the hydrorefined oil.
- the diluent if any, may be the oil used as a lubricant base and may include other additives such as those described hereinafter.
- the compositions of this invention are useful as industrial and gear lubricants.
- the lubricants provide longer lasting extreme pressure properties, anti-wear capability and reduced staining of copper parts.
- the lubricants of the invention can be used as crankcase lubricating oils for spark-ignited and compression- ignited internal combustion engines, including automobile and truck engines, two-cycle engines, aviation piston engines, marine and railroad diesel engines, and the like. They can also be used in gas engines, stationary power engines and turbines and the like. Automatic transmission fluids, transaxle lubricants, metal-working lubricants, hydraulic fluids and other lubricating oil and grease compositions can be prepared using the lubricant compositions of the present invention.
- the lubricants of this invention based on hydrorefined oil may contain small amounts of synthetic oils and natural oils refined by other methods. Generally, however, there is little advantage in using oil which is not hydrorefined.
- Natural oils include liquid petroleum oils and solvent-treated or acid-treated mineral lubricating oils of the paraffinic, naphthenic and mixed paraffinic-naphthenic types.
- Synthetic lubricating oils include hydrocarbon oils and halo-substituted hydrocarbon oils such as polymerized and interpolymerized olefins [e.g., polybutylenes, polypropylenes, propylene-isobutylene copolymers, chlorinated polybutylenes, poly(l-hexenes), poly(l-octenes), poly(l-decenes) and mixtures thereof, etc.]; alkylbenzenes [e.g., dodecylbenzenes, tetradecylbenzenes, dinonylbenzenes, di(2-ethylhexyl)benzenes, etc.]; polyphenyls (e.g., biphenyls, terphenyls, alkylated polyphenols, etc.); alkylated diphenyl ethers and alkylated diphenyl sulfides and the derivatives, analogs and homologs thereof
- Alkylene oxide polymers and interpolymers and derivatives thereof where the terminal hydroxyl groups have been modified by esterification, etherification, etc. constitute another class of known synthetic lubricating oils. These are exemplified by the oils prepared through polymerization of ethylene oxide or propylene oxide, the alkyl and aryl ethers of these polyoxyalkylene polymers (e.g., methyl-polyisopropylene glycol ether having an average molecular weight of 1000, diphenyl ether of polyethylene glycol having a molecular weight of 500-1000, diethyl ether of polypropylene glycol having a molecular weight of 1000-1500, etc.) or mono- and polycarboxylic esters thereof, for example, the acetic acid esters, mixed C 3 -C 8 fatty acid esters or the C 13 Oxo acid diester of tetraethylene glycol.
- the oils prepared through polymerization of ethylene oxide or propylene oxide the alkyl and aryl
- Another suitable class of synthetic lubricating oils comprises the esters of dicarboxylic acids (e.g., phthalic acid, succinic acid, alkyl succinic acids and alkenyl succinic acids, maleic acid, azelaic acid, suberic acid, sebacic acid, furmaric acid, adipic acid, linoleic acid dimer, malonic acid, alkyl malonic acids, alkenyl malonic acids, etc.) with a variety of alcohols (e.g., butyl alcohol, hexyl alcohol, dodecyl alcohol, 2-ethylhexyl alcohol, ethylene glycol, diethylene glycol monoether, propylene glycol, etc.).
- dicarboxylic acids e.g., phthalic acid, succinic acid, alkyl succinic acids and alkenyl succinic acids, maleic acid, azelaic acid, suberic acid, sebacic acid, furmaric acid, adipic acid

- Esters useful as synthetic oils also include those made from C 5 to C 12 monocarboxylic acids and polyols and polyol ethers such as neopentyl glycol, trimethylolpropane, pentaerythritol, dipentaerythritol and tripentaerythritol, etc.
- Silicon-based oils such as the polyalkyl-, polyaryl-, polyalkoxy-, or polyaryloxysiloxane oils and silicate oils comprise another useful class of synthetic lubricants; [e.g., tetraethyl silicate, tetraisopropyl silicate, tetra-(2-ethylhexyl) silicate, tetra-(4-methyl-2-ethylhexyl) silicate, tetra-(p-tert-butylphenyl) silicate, hexa-(4-methyl-2-pentoxy)disiloxane, poly(methyl)siloxanes, poly-(methylphenyl)siloxanes, etc.].
- synthetic lubricants e.g., tetraethyl silicate, tetraisopropyl silicate, tetra-(2-ethylhexyl) silicate, tetra-(4-
- Other synthetic lubricating oils include liquid esters of phosphorus-containing acids (e.g., tricresyl phosphate, trioctyl phosphate, diethyl ester of decylphosphonic acid, etc.) and polymeric tetrahydrofurans and the like.
- Unrefined oils are those obtained directly from a natural or synthetic source without further purification treatment.
- a shale oil obtained directly from retorting operations a petroleum oil obtained directly from distillation or ester oil obtained directly from an esterification process and used without further treatment would be an unrefined oil.
- Refined oils are similar to the unrefined oils except they have been further treated in one or more purification steps to improve one or more properties. Many such purification techniques are known to those of skill in the art such as solvent extraction, acid or base extraction, filtration,percolation, etc.
- Rerefined oils are obtained by processes similar to those used to obtain refined oils applied to refined oils which have been already used in service. Such rerefined oils are also known as reclaimed or reprocessed oils and often are additionally processed by techniques directed to removal of spent additives and oil breakdown products.
- the lubricants of the present invention contain an amount of the combination of components A and B sufficient to provide extreme pressure and anti-wear properties. Normally this amount will be about 0.01 to about 20%, preferably about 0.01 to about 10% of the total weight of the hydrorefined oil, component A.
- additives include, for example, detergents and dispersants of the ash-producing or ashless type, corrosion- and oxidation-inhibiting agents, pour point depressing agents, auxiliary extreme pressure agents, color stabilizers and anti-foam agents.
- the ash-producing detergents are exemplified by oil-soluble neutral and basic salts of alkali or alkaline earth metals with sulfonic acids, carboxylic acids, or organic phosphorus acids characterized by at least one direct carbon-to-phosphorus linkage such as those prepared by the treatment of an olefin polymer (e.g., polyisobutene having a molecular weight of 1000) with a phosphorizing agent such as phosphorus trichloride, phosphorus hepta- sulfide, phosphorus pentasulfide, phosphorus trichloride and sulfur, white phosphorus and a sulfur halide, or phosphoro- thioic chloride.
- olefin polymer e.g., polyisobutene having a molecular weight of 1000
- a phosphorizing agent such as phosphorus trichloride, phosphorus hepta- sulfide, phosphorus pent
- basic salt is used to designate metal salts wherein the metal is present in stoichiometrically larger amounts than the organic acid radical.
- the commonly employed methods for preparing the basic salts involve heating a mineral oil solution of an acid with a stoichiometric excess of a metal neutralizing agent such as the metal oxide, hydroxide, carbonate, bicarbonate, or sulfide at a temperature above 50°C. and filtering the resulting mass.
- a “promoter” in the neutralization step to aid the incorporation of a large excess of metal likewise is known.
- Examples of compounds useful as the promoter include phenolic substances such as phenol, naphthol, alkylphenol, thiophenol, sulfurized alkylphenol, and condensation products of formaldehyde with a phenolic substance; alcohols such as methanol, 2-propanol, octyl alcohol, cellosolve, carbitol, ethylene glycol, stearyl alcohol, and cyclohexyl alcohol; and amines such as aniline, phenylenediamine, phenothiazine, phenyl-S-naphthylamine, and dodecylamine.
- a particularly effective method for preparing the basic salts comprises mixing an acid with an excess of a basic alkaline earth metal neutralizing agent and at least one alcohol promoter, and carbonating the mixture at elevated temperatures such as 60-200°C.
- Ashless detergents and dispersants are so called despite the fact that, depending on its constitution, the dispersant may upon combustion yield a non-volatile material such as boric oxide or phosphorus pentoxide; however, it does not ordinarily contain metal and therefore does not yield a metal-containing ash on combustion.
- a non-volatile material such as boric oxide or phosphorus pentoxide
- Many types are known in the art, and any of them are suitable for use in the lubricants of this invention. The following are illustrative:
- chlorinated aliphatic hydrocarbons such as chlorinated wax
- aromatic sulfides and polysulfides such as benzyl disulfide, bis(chlorobenzyl)disulfide, bis-(chlorobenzyl)disulfide and sulfurized alkylphenol
- phosphosulfurized hydro-carbons such as the reaction product of a phosphorus sulfide with turpentine or methyl oleate
- phosphorus esters including principally dihydrocarbon and trihydrocarbon phosphites such as dibutyl phosphite, diheptyl phosphite, dicyclohexyl phosphite, pentylphenyl phosphite, dipentylphenyl phosphite, tridecyl phosphite, distearyl phosphite,
- Components B and C can be added directly to the hydrorefined oil. Preferably, however, they are diluted with a substantially inert, normally liquid organic diluent such as mineral oil, naphtha, benzene, toluene or xylene, to form an additive concentrate.
- a substantially inert, normally liquid organic diluent such as mineral oil, naphtha, benzene, toluene or xylene
- These concentrates usually contain about 20-90% by weight of the combination of components A and B such as the compositions of Examples 2-7 and may contain, in addition, one or more other additives known in the art or described hereinabove.
- Illustrative lubricants of this invention comprise principally a hydrorefined mineral oil in combination with about 0.1 to 10% by weight or more of the combinations of Examples 2 through 7 and with other known lubricant additives.
- the following specific examples in Table II illustrate lubricating compositions according to the invention.
- the lubricants of Examples 8-13 are prepared from concentrates of the indicated additives in a diluent oil.
- the lubricants of Examples 8-12 are prepared by blending 98 parts of the hydrorefined oil with 2 parts of concentrate, and Example 13 is prepared by blending 97 parts of hydrorefined oil with 3 parts of the concentrate.
