Title: Synthesis and characterization of a high-temperature, low-volatility phosphate additive for aerospace applications

Abstract

Tricresyl phosphate (TCP) is a widely used and effective antiwear additive for a variety of lubricants used in aerospace military applications. However, for a high-temperature gas turbine engine oil (GTO) application, volatility and thermo-oxidative stability limitations preclude the use of TCP. For this GTO application, high molecular weight, and thermally and thermo-oxidatively stable groups were incorporated into a phosphate-based additive. This paper describes the synthesis of this additive and its successful performance. 3 refs.
