Degradation Studies of a Di(2-Ethylhexyl) Adipate Lubricant Basestock.
Abstract
Employing a device known as the rotating cylinder rig for the formation of controlled-thickness thin films (0.004 in.), studies are described to examine the mechanisms of degradation of an uninhibited diester lubricant basestock, di(2-ethylhexyl) adipate. Experiments were performed to investigate the thermal (inert atmosphere) and oxidative (air atmosphere) stability of the diester, and the effect of moisture for both atmosphere types. Program objectives included elucidation of the chemical processes involved in fluid deterioration, particularly as related to the formation of deposits. Reactants and products were measured by various analytical techniques, principally gas chromatography, gas chromatography/mass spectrometry, and X-ray fluorescence spectrometry. (Author)
