Title: Improvements in or relating to lubricating oil composition
IPC: C08G65/28
Filed: 1951-12-21
Abstract: A lubricating oil is given anti-rusting properties by incorporating small amounts of an oil-soluble calcium petroleum sulphonate, an oil-miscible alkylphenoxypolyethoxyethanol having from 2-6 ether groups, and an alkaline-earth metal salt of an alkyl phenol sulphide. The sulphonates are salts of "mahogany" acids and may contain a stoichiometric amount of calcium or an excess thereof over the sulphonic acid.  Molecular weights may be 750-1100, and the amount may be 0.4-10, preferably 0.5-5 per cent. of the final composition. The polyether alcohol contains a phenoxy radical having at least one, and preferably not more than two alkyl groups such as butyl up to dodecyl.  Preferably there are 5 ether groups and one alkyl. particularly a tertiary alkyl derived from di-isobutene.  The amount used is from 0.05 to about 3-4, the solubility limit, preferably from 0.2-2 per cent. of the total composition: The salts of alkyl phenol sulphides are those of Ca, Ba, Sr, Mg or mixtures of two of these. At least one mol of the metal compound may be used for each phenol radical to form the known high metal content sulphides.  The benzene nucleus contains one or more alkyl groups, each of at least 4 carbon atoms.  Preferably the benzene nuclei are connected by 1-4 sulphur atoms.  The amount used is about 0.2-10, preferably 0.5-5 per cent. of the total composition.  The weight rates of this salt to the calcium sulphonate should, preferably, be from 0.1-3.5.  The lubricating oil may be a mineral oil, hydrogenated oil or white oil, synthetic oil from olefin polymerization, carbon oxides and hydrogen or hydrogenation of coal, coal tar or shale distillates, animal, vegetable or fish oils or mixtures thereof.  Dyes, pour depressors, sulphurized oils, anti-oxidants, resins, rubber, voltolized oils, colloidal solids such as graphite or zinc oxide, and the like may be added.  Examples compare the anti-rust effect of the three additives, calcium petroleum sulphonates, tert.-octyl phenyl ether alcohol having 5 ether groups and barium tert.-octyl phenol sulphide with that of one or two additives, and the effect of varying the ratio of this phenol sulphide salt to the calcium sulphonate.  Other examples use the calcium-barium salt of tert.-octyl phenol sulphide and a polyether alcohol having 3 other groups.
