This invention deals with the composition of lubricating mediums. More particularly, it relates to the improvement of lubricating mediums by means of multi-functional complex organic co-reaction products, which when mixed with various amounts of organic lubricating bodies or other neutral mediums produce a transformation in the product, the consistency of which varies from a thin medium to a solid mass, and the transition temperature of which is substantially increased from the non-fluid to the fluid phase. The composition may be used as a lubricating base which is readily soluble in organic lubricating bodies, or may be designed so as to form stable lubricating emulsions with water or-water soluble mediums.
By this invention, lubricants may be prepared to withstand wide temperature changes without marked changes in consistency. For example, a lubricant may be made which withstands temperatures ranging from about minus 100 F. and
. to about plus 400 F. withoutmarked change in consistency or breakdown. Also, stable, high temperature lubricating greases may be prepared without the use of heavy metal soaps, thereby obviating such disadvantages as corrosion, bleeding and soap separation, which usually results in poor lubrication. Such lubricants are especially adaptable for dynamos, pumps, Diesel, truck and airplane engines;
Another object of this invention is to produce a lubricant for tanks, turbines, hypoid gears, and alloy bearings, which are subject to high pressures, high temperatures, excessive friction, oxidation and corrosion.
Still another object of this invention is to employ such composition as an additive in lubricating oils for internal combustion engines, since it possesses properties which inhibit sludge, piston and ring sticking, and varnish and lacquer formation.
A further obect of this invention is to produce an oil or water soluble medium applicable as a machining lubricant, such as for cutting, drilling, reaming, broaching, milling, threading, grinding, hot forging, cold and hot stamping, drawing and for plastic col'd working of metals.
The foregoing and related ends are obtained by producing a co-reaction, in proper proportions, between organic nitrogen base-organic acid reaction product and an oxidized mixture of organic lubricating bodies and organic sulphoccmpounds. These various materials co-react to form a homogeneous compound.
In the term organic nitrogen base organic reaction product, the following are meant to be included: (1) amine organic acid reaction products and (2) quaternary ammonium hydroxide organic acid reaction products. As representative of the first class are the following: a reaction Claims. (01; 252-332) Application September 17, 1945,
product prepared from alkylamines, alkyl polyamines, alkylolamines, polyalkylene polyamines, alicyclic amines, aralkylamines, heterocyclic basic nitrogen compounds, etc. A representative of the second class are: tetra-alkyl ammonium hydroxides, and aryl-aralkyl ammonium hydroxides, etc., with 'various organic acids. These acids may be mono or polycarboxylic acids of the aliphatic and aromatic series; also organic sulphonic acids, such as p-toluene sulphonic acid, paradiphenylsulphonic acid, quinolinesulphonic acid, etc. However, the carboxylic acids aresgenerally more satisfactory.
More specifically, such amines as diethylamine, mono-amylamine, di-amylamine, and triamylamine, di-n-butylamine, monobutylamine, dibutylamine, undecylic amine, laurylamine, myristic amine, palmitylamine, stearylamine, mono, di, and triethanolamine, laurylolamine, palmitylolamine, stearylolamine, .ethylene diamine, diamino-isopropanol, triethylene tetramine, cyclohexylamine, dicyclohexylamine, benzylamine, morpholine, piperidine, pyridine, quinoline, cephalin, lecithin, trimethyl benzyl, ammonium hy-' droxyl, dimethyl-dibenzylammonium hydroxide,
tetraethyl ammonium hydroxide, Alkaterge-O an oil-soluble substituted oxazoline the properties of which are fully described in the Handbook of Material Trade Names by Zimmerman and Lavine and manufactured by Commercial Solvents Corporation, etc., are suitable.
Among the organic acids which are suitabe are: capric, undecylic, lauric, myristic, anachidic, anthranilic, stearic, oleic, palmitic, ricinoleic, linoleic, oxalic, succinic, glutarlc, adipic, sebacic, lactic, maleic, malic, tartaric, citric, benzoic, toluic, cinnamic, salicyclic, peanut-oil fatty acids, soy bean oil fatty acids, hydrogenated soy bean oil fatty acids, hydrogenated fish oil fatty acids, degras fatty acids, naphthenic acids, acids prepared by oxidation of petroleum hydrocarbons,

condensation products, polyalkylated diphenylsulphonates, higher sulphated secondary alcohols, higher alkyl sulphated alcohols, sulphonated castor oil, sodium taurocholate, etc. More specifically, the following compounds have been found satisfactory: the esters of sulpho-succinic acid, sulphated higher primary alcohols, formaldehyde condensation product of di-isopropylated naphnormally present in the various ingredients.
thalene B sulphonic acid, sodium taurocholate,
sulphonated castor oil, petroleum sulphonic acids miscible in either oil and/or water, di-secondary desired properties.
The oxidizing agents for the organic lubricating bodies-organic sulpho reaction products may be any well-known oxidizing agents, such as air, KMn04, H202, P205, P203, P204, ozone, chromates, organic peroxides, such as benzoyl peroxide, acetyl peroxide, ultra violet rays, X-rays, actinic rays, etc.
It is important to note that during the acid treatment of mineral oil, or other organic lubricating bodies, to produce sulfonates, the action of the acid or of the acid and oxygen of the air upon the organic lubricating body has an oxidizing efiect during the period of reaction. After the sludge and impurities have been removed, the resultant product comprises mixtures 'ofoxidized organic lubricating bodies and its oxidized sulf o compounds. This may be used as such, or the oxidized suli'o compound may be removed by conventional methods which usually'contain from 20 to 80% of the entrained organic lubricating bodies and these may be used to react with the amineorganic acid reaction product to form the desired lubricating complex co-reaction base. If the removed resultant productcontains less than about 1% of reacted oxygen, the product should be subjected to further oxidation. Hence, for purposes of this application and claims, the term oxidized organic lubricating bodies shall comprise bodies subjected to oxidation of the extracted oxidized sulfo components from this treated body. The resultant lubricating complex base may be further commingled with ordinary mineral oil, organic lubricating bodies, or with other than oil soluble medium, such as water, glycerine, glycols, etc.
Since there are a vast number of both. the
used. Usually the temperature varies from room temperature to the boiling point of the component parts, and the time of reaction varies from a fraction of an hour to about eight hours. The amounts of amine and respective organic acid used are related to approximately the molecular weight of each ingredient. In some cases, it is desirable to have present an excess of amine in the final product because of its stabilizing effect, its value in counteracting corrosion, its value in accentuating a desirable phase relationship with the medium which is compounded with it, or to improve the refractive index of the combined composition, or to eflect any combination of the above mentioned functions. The relative amount of oxidized organic lubricating medium sulfo organic compound used varies from approximately equal molecular proportions to about fifty tothe amineorganieacid reaction product. I
Also, in may instances where it is desired to modify organic lubricating mediums other than oil soluble ones, such as water or water soluble substances such as glycerol, ethylene glycol, a1-
' cohol, ketone, esters, aldehydes, etc., the amine is increased above its molecular weight combining power, in order to obtain a more stable and desirable product.
The method of preparing this complex base is simple, requiringno specially designed complex equipment or delicate control. The following examples are used for purposes of illustration and should not be construed in any way as a limitation of the invention.

However, these reaction products may be so chosen that they are relatively miscible in lubricating organic bodies, and if desired, are also miscible in aqueous mixtures.
The amount of the complex co-reaction product will be determined, in general, by the nature of the components used, the medium with which it is admixed, and the characteristics desired of the lubricant.

Usually from 0.1-50% and, in many through the mixture under constant agitation. At the end of this period, the air is cut of! and the amine-organic acid reaction product is slowly stirred into the oxidized mixture.

If desired, this reaction product may be used as is or the mixture may be purified by dissolving it in an inert solvent, washing it, removing the aqueous liquid and the inert solvent. The above amine-organic acid reaction product is slowly stirred into the purified or unpurified oxidized mixture of oil-sulpho castor oil mixture, and the entire mixture is heated to an elevated temperature and admixed with from one to ten parts of pale oil.
The complex co-reaction lubricating base is soluble in lubricating oil.
Various other organic reagents can be incorporated with the complex co-reaction base composition either during the mixing process or after it has been compounded in order to enhance lubricating and/or physical properties.

II. Cutting compositions prepared as disclosed in column 6, lines 19 to 59 inclusive, in mineral oil or m'odified'so asto be miscible with water, were used as cutting compounds on different machines cutting and drawing 'variousmetals and metal alloys. After the employment oi. over 100,000 gallons of the base composition, an increase of up to about sevenfold in tool life at a material increase in machining speed and feed hasbeen observedi The products 01' thisainvention in their undiluted form possess strong bactericidal and bacteriostatic' properties. Certain autotrophic bacteria; which are completely'non-pathogenic for man and which have been found as air and soil contaminants in these productsare rendered in capable of multiplication in the undiluted products; when diluted with water or oil, the bacteriostatic properties, with respect to the autotrophio organisms, are reduced and a certain amount of growth occurs.
These products are, however, bactericidal in their undiluted form and strongly bacteriostatic when diluted for the heterotrophic group of organisms which contains pathogenic forms for man. When these products are diluted with water or oil, the bactericidal properties are reduced but the bacteriostatic properties against the heterotrophs remains.
It may be stated then that the bacteria found as contaminants in oil or emulsions containing compositions of this invention do not usually correspond to any, of the bacteria known to be pathogenic for man. Such bacteria as have been found in the products of this invention are non-pathogenic contaminants that "may enter any exposed material from the air, dust, or hands of workers.
The problem of dermititis by the use of products of this invention as cutting compounds is reduced to a minimum.
This composition has an additional advantage in that it i capable cides, such as formaldehyde, creosote, dior tricreosote, etc., so their usual obnoxious and irritating odor is mitigated to practically nil.
This invention has been presented in detail and with numerous examples. This has been done by way of illustration only and with the intention that no limitation should be imposed upon the invention thereby. effected in the practice of the invention which are within the scope of the following claims.
