Improvements in or relating to lubricating compositions and additives therefor

The invention comprises an additive for lubricating oils (see Group III), said additive being a compound obtained by the sulphurization or sulphurization and phosphorization of the unsaponifiable matter extracted from saponified wool grease, or a metal salt of such a sulphurized and phosphorized compound. The unsaponifiable matter may be sulphurized by heating with sulphur and the reaction may be assisted by adding a small amount of sulphur monochloride or sulphur dichloride. The sulphurized product may then be phosphorized by reacting it with a phosphorus compound, e.g. a phosphorus sulphide or halide and particularly phosphorus pentasulphide or sesquisulphide, e.g. by heating with either of the latter at 220 DEG to 250 DEG F. Alternatively, the unsaponifiable matter may be reacted with sulphur chlorides in oil or an inert solvent and the chlorine then replaced by sulphur, or phosphorus and sulphur, by reacting the product in a suitable solvent with sodium sulphide or polysulphide or the sodium salt of an organic dithiophosphoric acid. The sulphurization of the unsaponifiable material may be carried out in the presence of a vulcanization accelerator, e.g. mercaptobenzothiazole, benzothiazole disulphide, tetramethyl and tetraethyl thiuram disulphides or mixtures of these compounds with diphenyl guanidine. It is preferred to carry out the sulphurization in the presence of an aliphatic, alicyclic, or reduced heterocyclic secondary amine such as dicyclohexylamine, diethanolamine, or morpholine and the sulphurization is facilitated by carrying it out in the presence of mineral oil. The products may be freed from oil-insoluble impurities by dissolving in a suitable solvent such as petroleum ether, filtering, and then removing the solvent by distillation. Alternatively, the phosphorized - sulphurized reaction products may be heated in oil solution with a minor amount of an aqueous suspension of lime or baryta and then filtered with the addition of filter-aid material.

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.
