Lubricating oil additives

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.

Method for producing waxes and grease base stocks through catalytic depolymerisation of waste plastics

In a process for converting mixed polyethylene waste to make waxes and grease base stocks through catalytic depolymerization, the mixed polyethylene waste is preheated to form a molten mixed polyethylene waste. Then, depolymerization reaction of the molten mixed polyethylene waste is started. The depolymerization reaction uses a catalyst in a high pressure reactor at a desired temperature using heaters in the high pressure reactor. The catalyst is disposed on a stirring blade. Progression of depolymerization reaction of the molten mixed polyethylene waste is allowed to continue until a pressure in the high pressure reactor reaches a desired value. The heaters are turned off and depolymerization reaction of the molten mixed polyethylene waste is stopped upon the pressure in the reactor reaching desired value. The mixed polyethylene waste is converted to wax or grease base stock.
