POLYNUCLEAR AROMATIC COMPOUNDS FOR HIGH TEMPERATURE LUBRICANTS

Abstract

The properties of triaryl esters of phosphoric acid were studied with regard to their suitability tor high temperature lubricants and related materials. It was found that naphthyl derivatives did not have sufficient thermal stability to compensate for the unwanted increase in viscosity and melting point. The 4-biphenylyl group possessed all the advantages of the naphthyl group with mach better thermal stability. One particular compound prepared, bis(o-chlorophenyl) 4-biphenylyl phosphate had a thermal stability of over 510 C (950 F), by far the highest stability of any compound prepared wider this contract.
