Description

Patented Aug. 9, 1938 UNITED STATES PATENT OFFICE LUBRICATIN G OIL Leo Liberthson, New York, N. Y., assignor to L.
Sonneborn Sons Inc a corporation of Dela- This invention relates to lubricating oils.
An object of the invention is the provision of a lubricating oil which will not appreciably corrode metal surfaces.
A lubricating oil derived from a Pennsylvania paraffin base crude and containing varying amounts of paraifinic constituents will corrode metal or alloy surfaces with which it comes in contact under temperature and pressure conditions obtaining in practice, and in many cases to such an extent, that the metal will, after a period of time, be deteriorated to a point where it must be replaced. The relatively short life of the metal renders its use expensive, and its replacement in many cases inconvenient.
I have discovered that the addition of from 0.05 to 0.5% of cobalt mahogany sulphonate will give to such Pennsylvania paraflin base lubricating oil anti-corrosive properties, and that metal or alloy surfaces coming in contact with such blended oil will not be corroded to the extent that has heretofore been experienced.
The cobalt mahogany sulphonate may be obtained by treating a lubricating oil fraction, for
example, a fraction derived from a naphthenic base crude with sulphuric acid, preferably oleum. Such treatment yields an acid sludge, which contains water soluble green sulphonic acids, and
w an oil layer which contains oil soluble, mahogany sulphonic acids. The oil layer is separated from the acid sludge and treated with alkali, such as sodium or potassium hydroxide, whereupon sodium or potassium mahogany sulphonate is' formed. The mahogany sulphonate can be extracted from such oil by treatment with an organic solvent, such as an aqueous alcoholic solution. Upon distillation of the alcoholic solution, the alkali metal mahogany sulphonate is recovered. The alkali metal mahogany sulphonate is 40 dispersed in water at an elevated temperature,
' for example, at about 100 (3., a soluble cobalt salt is added, and the cobalt mahogany sulphonate is precipitated.
The lubricating oil to which the said sulphonate is added, is one derived from a Pennsylvania paraflin base crude, for example, a straight distillate containing varying amounts of paraflinic constituents or may consist predominantly of the same. It is common practice to blend straight distillates with small amounts of bottoms, for 5 example, an S. A. E. 20 commercial grade of straight distillate and 10% bottoms.
The addition of from 0.05 to 0.5% of cobalt mahogany sulphonate to a lubricating oil derived from a Pennsylvania paraflin base crude and 10 containing varying amounts of parafiinic constituents yields an oil which will not cause the corrosion normally associated with an oil not so treated, and metal or alloy surfaces which come in contact with my novel lubricant will experi- 1 ence a much longer life.
The above description is for purposes of illustrationand not of limitation, and is not to be be limited except by the appended claims in which I have endeavored to claim all inherent novelty. 20
I claim:
1. A non-corroding lubricating oil composition consisting of a lubricating oil containing parafiinic constituents, and from 0.05 to 0.5% of a cobalt mahogany sulphonate, said lubricating 25 011 being derived from a Pennsylvania paraffin base crude.
2. A non-corroding lubricating Oil composition consisting of a lubricating oil distillate contain ing paraflinic constituents, and from 0.05 to 0.5% 30 of a cobalt mahogany sulphonate, said lubricating oil distillate being derived from a Pennsylvania parafiin base crude.
3. A non-corroding lubricating oil composition consisting predominantly of a lubricating oil dis- 35 tillate containing paraffinic constituents, and from 0.05 to 0.5% of a cobalt mahogany sulphonate, said lubricating oil distillate being derived from a Pennsylvania paraffin base crude.
4. A non-corroding lubricating oil composition consisting of a lubricating oil derived from a Pennsylvania parafiin base crude, paraflinic matter, and from 0.05 to 0.5% of a cobalt mahogany sulphonate.
