Patented Jan. 16, 1945 LUBRICANTS Lawson W. Mixon and Clarence M. Loane, Ham

13 Claims.
The present invention relates to lubricants, and particularly to improvements in lubricating oil compositions intended for use in internal combustion engines such as automobile and Diesel engines, under severe conditions, wherein corrosion due to acidity. piston ring sticking, cylinder wear, carbon sludge. varnish formation and viscosity increase may be encountered.
Straight petroleum lubricants are efiective within certain defined limits of engine operating conditions but when these limits are exceeded, such lubricants frequently fail to give the desired performance demanded of them. Since in modern engines designed to give increased performance these limits are frequently exceeded, the use of straight mineral oils as lubricants produces undesirable conditions within the engine; thus varnish, carbon and sludge formation is excessive and corroson of improved hard metal alloy bearings due to acidity is encountered.
It is an object of the present invention to provide a lubricant for internal combustion engines which will be effective in providing adequate inbricat'nn for such engines. It is a further object of the invention to provide a lubricant which will not be inducive to the formation of varnish and/r sludge, nor ind-ucive to an increase of viscosity. Another object of the invention is to prov'de a lubricant Which will reduce engine wear and be non-corrosive to bearings. Other objects and advantages of the invention will become apparent as the description thereof proceeds.
We have discovered that the forego'ng objects may be attained by employing a lubricating oil containing small amounts of the reaction product of a hydrocarbon or mixture thereof with chlorosulfonic acirl. If desired, the reaction product may be neutralized by forming the metal salts thereof. Furthermore, the reaction product may be reacted with a sulfur and/or a phosphcruscontaining compound, either before or after ncutralization. Also, the hydrocarbon may be treated with the sulfur and/or phosphorus-contaningv particularly suitable. These hydrocarbons may be heavy oils, olefin polymers, parafiins, olefins, aromatics, alkylated aromatics, cyclic aliphatics, petroleum fractions, such as lubricating oil fractions, waxes, petrolatum, solvent extracts of petroleum fractions, cracked cycle stocks or condensation products of petroleum fractions, or the like. Aliphatic compounds are usually preferred over the aromatic compounds.
Essentially saturated hydrocarbons such as bright stock residuums, lubricating oil distillates, petrolatums, or parafiln waxes maybe used. We may also employ the products resulting from the condensation of any of the foregoing hydrocarbons, usually thru first halogenating the hydrocarbons, with aromatic hydrocarbons in the presence of anhydrous inorganic halides, such as aluminum chloride, zinc chloride, boron fluoride and the like.
We preferably-employ olefin polymers having molecularweights above and preferably between 500 and 3000. As olefinlc starting materials for the productionof such polymers, we may employ the individual olefins themselves, mixtures of olefins, or mixtures of olefins and non-olefinic compounds. For example, the olefinic starting material maybe propylene, butylene, amylenes, refinery gases containing normally gaseous olefins and cracked distillates or other relatively low-boiling hydrocarbon mixtures containing normally liquid olefins and mixtures of normally liquid olefins, containing substantial amounts of dissolved normally gaseous olefins. We may also employ olefins obtained by the cracking of paraffin wax or by the dehalogenation of alkyl halides, particularly long chain alkyl halides.
The polymers referred to above may be those obtained by polymerizing olefinic hydrocarbons in the presence of catalysts such as sulfuric acid, phosphoric acid, or aluminum chloride, zinc chloride, boron fluoride and other catalysts of the Frledel-Crafts type. For example, we may employ the polymers resulting from thetreatment of monoolefins preferably isomonoolefins such as isobutylene and isoamylene and/or the copolymers obtained by the polymerization of hydrocarbon mixtures containing low molecular weight isoolefins and normal olefins, preferably those of less than six carbon atoms.
We may also employ as the starting material the polymer or synthetic lubricating oil obtained by polymerizing unsaturated hydrocarbons resulting from the vapor phase cracking of parafiin waxes in the presence of aluminum chloride which is fully described in United States Patents Nos.
1,995,260, 1,970,002 and 2,091,398. Still another type oi olefin polymer which may be employed is the polymer resulting from the treatment of vapor phase cracked gasoline and/or gasoline fractions desired, subsequent to the neutralization step by treating with SzClz, PCla, or the like.
The desired product, whether the hydrocarbon chlorosulfonic acid reaction product, the metal with sulfuric acid or solid absorbents such as 6 salt of the reaction product or the neutralized fuller's earth whereby unsaturated polymerized reaction product, may be used in lubricating oils, hydrocarbons are removed. alone or in combination with other well-known Any of the above-mentioned hydrocarbons may lubricant additives, in amounts from about 0.05 be reacted with chlomsulfonlc acid to produce a. per cent to about 10 per cent.
