Patent GB-424380-A (GB)
Title: Improvements in or relating to lubricants and lubricating
IPC: C10M177/00
Filed: 1934-03-07
Abstract: Lubricants, especially for use under high pressures, consist of a lubricating oil to which is added a compound of phosphorus or arsenic such as an ester and similar compounds containing an organic radicle with a long chain.  Esters in which the phosphorus or arsenic atom is connected to an aryl nucleus through an oxygen or sulphur atom are excluded.  Suitable compounds are made by heating castor oil with phosphorus or arsenic pentoxide at 70 DEG  C. to form a partially esterified castor oil.  The product may be further heated in an atmosphere of carbon dioxide.  The resulting composition may be used alone or in admixture with mineral or fatty lubricating oils, or the compounds may be formed therein by adding lubricating oil to the initial materials.  The ester may also be made by using phosphorus oxychloride in the presence of pyridine.  Similar esters may be formed using wool fat alcohols or the oxyacids obtained from the oxidation products of paraffin wax.  Tri-b -naphthyl phosphate may also be used.  In use, the substances react with the metal surface being lubricated to form a thin layer of a new compound which is continually swept away and replaced.  The compounds formed are insoluble in water whereby corrosion of the metal surface is avoided.
