Abstract
A lubricating grease, especially suitable for high temperature lubrication, comprises 60-95 per cent by weight of a lubricating oil, 3-30 per cent of an alkali metal soap of fatty acids having 12-22 carbon atoms in the molecule 0.1-10 per cent of an alkali metal salt of a monocarboxylic acid having 1-5 carbon atoms in the molecule and 1-8 per cent of a vegetable wax. The lubricating oil is preferably mineral oil, while the soap may be an alkali metal soap of oleic or stearic acid, particularly sodium or lithium oleate or stearate. The alkali metal salt of a monocarboxylic acid having 1-5 carbon atoms in the molecule is preferably an alkali metal acetate or formate, particularly sodium or lithium acetate. These salts may be added as such to the grease compositions, or the corresponding acids may be added, provided there is sufficient alkali in the grease composition to neutralize these acids and to saponify the fatty acids. Alternatively, the alkali metal salts of monocarboxylic acids having 1-5 carbon atoms in the molecule are incorporated in the grease composition by mixing glycerin with the rest of the grease-forming components before the grease is cooked, so that these salts are formed in situ by decomposition of the glycerin. Vegetable waxes which may be employed are candelilla, carnauba, bayberry and Japan waxes. These waxes are employed as soap-dispersing agents and the grease composition may contain montan wax or an oil-soluble metal petroleum sulphonate, particularly sodium petroleum sulphonate, as an additional soap-dispersing agent. In the examples, grease compositions are prepared from mixtures of (1) oleic acid or hydrogenated menhaden oil fatty acids, acetic acid, sodium hydroxide, mineral lubriating oil and candelilla wax or (2) stearic acid, acetic acid, lithium hydroxide monohydrate, mineral lubricating oil and candelilla wax. For comparison purposes, similar compositions are described from which the candelilla wax has been omitted. Specification 643,536 is referred to. The Specification as open to inspection under Sect. 91, refers to grease compositions comprising an alkali metal soap of a fatty acid having 12-22 carbon atoms in the molecule and 0.1-10 per cent by weight of a saturated monocarboxylic acid having 1-5 carbon atoms in the molecule or of a compound, such as glycerin or a glyceride, which when heated in the presence of excess caustic alkali decomposes to produce such acids. In an example, a grease composition is prepared from a mixture of oleic acid, sodium hydroxide, mineral lubricating oil and glycerin. For comparison purposes, a grease composition is described which is prepared from a mixture of oleic acid, sodium hydroxide and mineral lubricating oil; an excess of sodium hydroxide is employed and the mixture is cooked until the excess is reduced to 1 per cent. The resulting grease contains sodium carbonate. This subject-matter does not appear in the Specification as accepted.
