Abstract

A lubricating composition comprises a hydrocarbon oil and a specified proportion of an aliphatic ester of a halogenated fatty acid, the ester molecule containing 3 halogen atoms attached to the end of the chain remote from the esterified carboxyl group and a fourth halogen atom attached in position 2 with respect to the end halogenated group. Thus the preferred ester of a halogenated fatty acid is methyl tetrachlorolaurate of formula Cl3C.CH2.CHCl.(CH2)8.COOCH3. An extreme pressure lubricant contains the hydrocarbon oil together with 1-8 per cent of the ester of the halogenated fatty acid, while a lubricant suitable for use both at moderate pressures and at extreme pressures contains the hydrocarbon oil, 0.1-2 per cent of the ester of the halogenated fatty acid and 0.2-2 per cent of an aliphatic ester of an unhalogenated fatty acid, this latter ester having more than 12 carbon atoms in the molecule. The latter ester may be an ester of stearic or palmitic acid, particularly methyl or ethyl stearate. The hydrocarbon oil may be mineral oil or oil obtained by the distillation of coal. In an example, a lubricating composition is described which consists of mineral oil, 1 per cent of methyl tetrachlorolaurate and 1 per cent of methyl stearate.
