Vapour pressure of lubricants. P.A. Bessette. NLGI Spokesm., June 1994, 58(3), 8--12.
A low-cost apparatus for measuring the vapour pressure of greases and oils is described and illustrated. It measures the vapour pressure at elevated temperature and reduced pressure. Factors affecting volatility and vapour pressure are described as chemical homogeneity, molecular weight, temperature, pressure/vacuum, intermolecular affinity, and thermo-oxidative stability. Data for eight oils and seven greases are presented for test samples that span wide ranges of base oil types, viscosities and molecular weights. The grease thickeners used are a sodium complex, clay, lithium stearate, an aluminium complex, and PTFE. 8 refs.
