Definitions

• This invention relates to lubricants and more particularly to gear lubricants for use under extremely high pressure and over a Wide range of temperature conditions.
• Lubricants of this type for semi-open or open gear lubrication must be viscous and they should be capable of carrying highloads at elevated temperatures. Such lubricants must have good adhesive properties so as not to be thrown olf the running gears. They must be water-resistant and they should be in a form which can be easily handled and applied.
• An object of the present invention is to provide a lubricant having good high temperature and pressure properties. vide a lubricant of good adhesive properties over wide temperature conditions. Still another object of this invention is to provide a lubricant which is water-resistant and which is easy to use and apply. Other objects will become apparent from the detailed description of the invention.
• a lubricant comprising (I) a major portion of a base mixture of substantial proportions each of a mineral oil of lubricating viscosity and an asphalt obtained from such sources as asphaltic base crudes and which is predominantly aromatic in character and (II) a minor portion of the combination of minor proportions each of three essential additives, namely: (1) an oil-soluble heavy metal soap, (2) an oil-soluble polyhalohydrocarbon thiocarbamate and (3) an oil-soluble ester of a high molecular weight aliphatic carboxylic acid and a low molecular weight monohydroxy alcohol.
• the mineral oil component of the base (I) can be a liquid hydrocarbon of natural or synthetic origin and can range in viscosity from a light distillate mineral oil fraction to a heavy lubricating oil, such as gas oil, mineral lubricating oil, cylinder stock or Bright Stock or mixtures thereof. Mineral lubricating oils ranging in viscosity from 40 to 150 SSU at 210 F. are preferred.
• the asphalt component of the base (I) can be obtained from various asphaltic crudes using various processes known to the art.
• the preferred asphaltic bitumens are those which have softening points between about 100 F. and 250 F. and preferably between 100 F. and 150 F. and which are predominantly arohaving the properties given in Table 1.

• One of the three essential additives incorporated in the compositions is an oil-soluble heavy metal salt or soap, of a cyclic carboxylic acid,,of an organic sulfonic acid, of a high molecular weight fatty acid and mixtures thereof, such as lead or zinc salts of cyclic carboxylic acids, such as naphthenic acid, abietic acid and other resin acids; of organic sulfonic acids, such as petroleum .sulfonic acids, and of higher fatty acids, such as oleic acid, stearic acid and the like; lead salts of cyclic carbloxylic acid, e.g., lead naphthenate represent a preferred c ass.
• the naphthenic acids and their refined product can be prepared by the processes described in US. Patents 2,200,711, 2,214,438, 2,296,039 and 2,537,516.

• R and R are hydrocarbon radicals containing a total of at least 12 carbon atoms, at least one of them preferably being an aliphatic hydrocarbon radical of at least 10 carbon atoms, preferably from 12 to 30 carbon atoms and having at least two substituent halogen atoms
• R is preferably a long-chain aliphatic radical.
• halohydrocarbon thiocarbonate esters are suitably prepared by the reaction of polyhalohydrocarbons with less than the stoichiornetrically equivalent amount of an alkali or of an alkali earth metal organo thiocarbonate, with the formation of the alkali or alkali earth metal halide and the thiocarbonate full ester.
• the thiocarbonate may be a mono-, dior tri-thiocarbonate.
• various alkali or alkali metal organo thiocarbonates can be suitably used, such as the sodium, potassium, calciumand barium hydr0- carbon Xanthates and corresponding monoor tri-thiocarbonates.
• Illustrative suitable substances are alkali metal lower alkyl xanthates, such as sodium methyl xanthate, potassium methyl xanthate, potassium ethyl xanthate, potassium butyl xanthate, sodium amyl Xanthate, and potassium amyl xanthate and alkali metal cule.

• the polyhalogenated hydrocarbons are preferably polych-lorinated aliphatic hydrocarbons of from about 2 to about 30 carbon atoms per mole- Mixtures of polychloroalkanes, including cyclic and acyclic alkanes, are particularly useful, giving products which are somewhat more compatible with the other components of the composition over a wider temperature range.
• Polyhaloalkenes are also useful reactants. Some readily available materials which may be used are chlori- --nated naphtha, chlorinated paraflinic lubricating oil mixture of hydrocarbons, chlorinated paraffin wax and chlorinated rubber.
• the reactants are reacted in proportions such that the final product contains both chlorine and thiocarbonate groups.
• the amounts of chlorine and sulfur in the final product can vary over a wide range such as from about 25 to about 40% byv weight chlorine and from about 7 to about 15% sulfur.
• Example I One hundred parts of 'chlornaphtha (chlorinated Stoddard solvent of 49% chlorine content) was reacted with 52 parts of potassium methyl xanthate (CH-,-O-CSSK), using acetone as a solvent .and following the same general procedure described above, except that the mixture was refluxed for one hour. 7
• Example II Petroleum naphtha (Stoddard solvent) was chlorinated by bubbling chlorine gas therethrough until it contained about 52% 'by weight of chlorine. 225 parts by weight of the chlornaphtha was then admixed with about 400 content of about 10%, or a tri-thiocarbonate (divalent CS content of about 11.3%.
• a third. essential additive is an oil-soluble ester of a high molecular, weight monocarboxylic acid and a low molecular weight alcohol.
• Acids which can be used to form the esters include C to C fatty acids such as lauric, myristic, palmitic, stearic and oleic acids while the alcohols can be aliphatic monohydric alcohols such as methyl, ethyl, propyl, .butyl, hexyl and octyl alcohols,
