Improvements in and relating to the preparation of lubricating greases

A lubricating grease is prepared by dispersing a waterproofed clay or clay-like material in a lubricating oil in the presence of a polar organic compound miscible with the oil and having a dielectric constant greater than 10 at 20 DEG C. An increase in the gelling power of the clay, and a reduction in the milling necessary are obtained. The clay may be natural, particularly montmorillonite of high magnesia content, or synthetic clay or zeolite, e.g. made by coprecipitating silica and magnesia by adding magnesium chloride to potassium silicate solution, drying the gel, and heating with caustic soda at 240 DEG C and 450-550 p.s.i. to give a synthetic Hectorite. The magnesium chloride may be replaced by calcium, barium or aluminium chloride, and caustic soda by potash, ammonia or lithia. A preferred class of clays contains 2-20 per cent of alkaline-earth metal. The waterproofing may be effected by treating a clay hydrosol with a cationic surface active agent such as a quaternary ammonium compound or amine salt having at least one hydrocarbon radical of 12 or more carbon atoms or a partial amide of a fatty acid of at least 12 carbon atoms with a condensation product of ammonia or an amine with acrolein or its analogues or of ammonia with epichlorhydrin. The clay should contain at least 30 per cent by weight of hydrophobic surface active radicals. Another method of waterproofing clays comprises treating with a solution of a salt capable upon heating of forming basic salts, e.g. lead, barium or strontium salts of fatty acids, washing out unadsorbed salt and heating at 100-435 DEG C for 1-24 hours. Mineral lubricating oils are preferred but synthetic oils may be used such as alkylene oxide, glycol or olefin polymers, organic phosphates, silicone fluids, and carboxyclic esters. The polar compound is preferably a liquid boiling below 150 DEG C and having a dielectric constant of 15-35 at 20 DEG C. Typical compounds, including ketones, aldehydes, nitriles, acids, alcohols, ...

Lubricating grease preparation process

PROCESS FOR PREPARING PLASTIC AND LIQUID LUBRICANTS

Prodn. of lubricating oils and greases by dispersing thickners, additives and fillers in base fluids is carried out by means of ferromagnetic particles which form a vortex under the influence of a rotating magnetic field. The ferromagnetic particles can be of a magnetically soft or hard material (e.g. carbon steel, Ni or Co/Ni alloys) with a ratio of max. to min dimension of 6-20:1. The particles are pref. protected by a polymer coating. In the case of dispersing thickeners (e.g. metal soaps), these can be formed in situ by reaction of appropriate starting materials. High quality products can be produced in treatment times of a few seconds. Energy consumption is low. The process can be operated continuously and is readily automated.

Ester-based synthetic lubricants - derived from trimellitic acid for use as lubricating transmission and hydraulic fluids

Alkylaromatic hydrocarbon oligomers and their use as lubricating basestocks or as additives

Aromatic compounds are alkylated with C20-C1300 olefinic oligomers by contacting the oligomers and aromatic compounds with an acidic catalyst to produce novel alkylated aromatic hydrocarbon compositions useful as lubricant basestock and additives. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced chromium oxide catalyst on silica support. In one embodiment, the aromatic compounds are alkylated with a mono-olefinic HVI-PAO dimer which is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. The novel alkylaromatic compositions show improved thermal stability; also, the compositions are useful as lubricant additives for improved antiwear properties, antioxidant and other properties.

This invention relates to a composition comprising: (A) a major amount of a fluorine-containing hydrocarbon containing one or two carbon atoms; and (B) a minor amount of a soluble tertiary amide represented by the formula ##STR1## wherein a is one or two, provided that when a is one, R is a hydrocarbyl group or a hydrocarbylpolyoxyalkylene group, and when a is two, R is a hydrocarbylene group; each R 2 is independently hydrogen or an alkyl group having from 1 to about 8 carbon atoms; b is one or two; X is oxygen or N--R 3 ; R 3 is a hydrocarbyl group having 1 to about 18 carbon atoms or --C(O)R 4 , R 4 is a hydrocarbyl group or a hydrocarbylpolyoxyalkylene alkyl group. The present invention provides compositions which are useful as refrigeration liquids in refrigerators and air-conditioners including auto, home and industrial air-conditioners. The invention provides tertiary amides which are compatible with fluorine-containing hydrocarbons used in refrigerators and air conditioners. The tertiary amides act as a lubricant for air-conditioners.

Production of lubricants

Novel alkylaromatic lubricant fluids

Aromatic compounds are alkylated with C₂₀-C₁₃₀₀ olefinic oligomers by contacting the oligomers and aromatic compounds with an acidic catalyst to produce novel alkylated aromatic hydrocarbon compositions useful as lubricant basestock and additives. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced chromium oxide catalyst on silica support. In one embodiment, the aromatic compounds are alkylated with a mono-olefinic HVI-PAO dimer which is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. The novel alkylaromatic compositions show improved thermal stability; also, the compositions are useful as lubricant additives for improved antiwear properties, antioxidant and other properties.

Metal working lubricant

A metal-fabricating lubricant, for use in such operations as the rolling, drawing and forging of metals, comprises a major proportion of a substantially non-aromatic waxy hydrocarbon and 20-40 per cent by weight of a liquid hydrocarbon boiling within the range 300-700 DEG F. The non-aromatic waxy hydrocarbon may be of petroleum origin or may be prepared by polymerisation of olefins or dehydration of long-chain fatty alcohols. The liquid hydrocarbon may be gas oil, mineral seal oil, kerosene, undecane or dodecane. A list of optional ingredients which may be present in the lubricant is given. This list is subdivided into the following headings:-Animal, vegetable and marine oils; fatty acids; esters of carboxylic acids with mono- and poly-hydric alcohols; esters of inorganic acids; phosphatidic materials; sulphur-containing extreme pressure materials such as dibenzyl disulphide, sulphurized fatty oils and sulphurized fatty acids; halogenated extreme pressure organic materials; naturally occurring and synthetic waxes. In the examples, lubricants are described consisting of gas oil and (a) non-aromatic short residue petroleum (b) non-aromatic microcrystalline slop wax, or (c) non-aromatic Pennsylvania cylinder stock slop wax. For comparison purposes a lubricant is described consisting of palm oil and non-aromatic microcrystalline slop wax. Specifications 565,333 and 569,520 are referred to. The Specification as open to inspection under Sect. 91 refers to a metal-fabricating lubricant comprising a major proportion of a substantially non-aromatic waxy hydrocarbon and up to 40 per cent by weight of a light liquid hydrocarbon boiling below the lubricating oil range. Examples of suitable light liquid p hydrocarbons include petroleum naphtha cuts, mineral spirits, kerosene SO2 extract, petroleum ether, and paraffinic hydrocarbons such as normal hexane, dimethyl pentane, octane and isooctane. This subject-matter does not appear in the Specification as accepted.
