Definitions
- the flimrupture strength becomes more important than 'the coeilicient of friction. For example, under the extreme pressures obtaining in hypoid gears,
- the present invention is a development from. United States Patent No.
- proyids lubricants which no set conditions could be determined "active" sulphur, i. e. sulphur which will react they may contain a substantial quantity of chemically with metals such as copper at high temperatures, yet are relatively noncorrosive towards metals. especially copper, in practice under the conditions in which they are used.
- an extreme-pres? sure lubricant comprises a lubricating oil havins dispersed therein an aromatic'hydroxy-substi- .tuted' polysulphide comprising an ester substituent.
- Said polysulphlde comprises two aromatic radicals each of which contains both a hydroxyl and an ester substituent.
- the hydroxyl substituent in each aromatic radical is located tamed in'the oil mustbe in such form as to be I capable of rcactingwlth the metallic surfaces which it is desired to lubricate. the other in the paraposition to the 'polysulphide sroup.
- the invention contemplates the use of disulphides, trisulphides and tetrasulphides and of mixtures of such polysulphides in varying amount, and" also of mixtures of such polysulphides with varying amounts of the corresponding thioetherand of minor amounts of free sulphur.
- the testing machine employed was the wellknown Almen machine.
- the compounds of this invention impart a higher film-rupture strength to oils in which they are dissolved than the correspondin polysulphides made from phenols.
- the free sulphur may be removed, 7 at least in part, by maintaining the material at a temperature just above its melting point, and
- lubricatin oils e. g..mineral 'lubricating oils.
- these condiinvention may be added tomineral-oilg which may be parafllnic; naphthenic or asphaltic in type, or which may contain varying amounts of iatty oils (e. g. animal, vegetable and fish oils) 1 i or known addition agents such as pour-point depressants, viscosity index improvers, anti oxb. dants, sludge disperser-s and detergents and corrosion inhibitors gnch as mercaptobenzothiamle.
