Reaction of Phosphonium Phosphate Ionic Liquids with Iron Substrates
Joseph Martin Hancock
The reactions of several oil soluble phosphonium phosphate ionic liquids with iron substrates were investigated to determine their suitability as lubricant additives. The ionic liquids, dissolved in ester based lubricant base stocks were found to react with metal surfaces to form a phosphorus containing film. Scanning electron microscopy showed the deposition of a layer on the surface and x-ray fluorescence showed that the layer contained phosphorus. Infrared analysis of the film demonstrated the formation of poly phosphate chains on the material. Decomposition products from the ionic liquid were identified by GC-MS.
