The authors report how metal deactivator additives (MDA) exert a strong stabilizing effect on fuels when tested in the jet fuel thermal oxidation tester (JFTOT). At low concentrations, MDA was found to be very effective in the JFTOT in reducing insoluble reaction products but had no significant effect on fuel oxidation. In the presence of dissolved copper, MDA acted to reduce tube deposition over regions of the tube at which temperatures were higher than 250{degrees}C The deposits formed in the presence of copper at lower temperatures, which were not reduced by the MDA, were found to contain a high concentration of copper. MDA also partially counteracted the catalytic effects of dissolved copper on fuel autoxidation.
