Abstract
Natural or synthetic lubricating oils, hydraulic fluids and cutting oils contain as rust inhibitor an organophosphorus compound of formula <FORM:0902750/III/1> where R is alkyl or cycloalkyl, Y is oxygen or sulphur and may be both oxygen and sulphur in the same compound and n is an integer equal to or greater than 1.ALSO:The invention comprises compounds of formula <FORM:0902750/IV (b)/1> where R is alkyl or cycloalkyl containing 6 or more carbon atoms, Y is oxygen or sulphur and may be both oxygen and sulphur in the same compound, and n is an integer equal to or greater than 1. They may be prepared by condensing a dihaloalkyl ether <FORM:0902750/IV (b)/2> where X is halogen, with a salt of formula <FORM:0902750/IV (b)/3> where M is an alkali metal, in the presence of an organic solvent, e.g. at 50-100 DEG C. Said salt may be prepared by the reaction of an alcohol or mercaptan RYH with a phosphorus sulphide or sulphohalide, e.g. at 80-120 DEG C., followed by neutralisation of the resulting acid with a strongly basic alkali metal compound. The products have rust-inhibiting properties, e.g. in lubricants, hydraulic fluids and cutting oils (see Group III).
