This Report describes experiments on oxidation and gum formation from n-dodecane, tetralin, and several Diesel fuels at 43, 60, and 100 C, with and without added initiators, t-butyl peroxide and 2,2azobis2-methylpropionitrile ABN. Experiments on gum determination and a manuscript for publication, Gum and Deposit Formation from Jet Turbine and Diesel Fuels at 100 C, are included. One objective of work on this Contract is to relate oxidations of diesel fuels at 100 and 130 C, where experiments can be performed in hours or days, to standard tests for fuel stability at ambient temperatures and 43.3 C 110 F, which require many weeks. A second objective is to devise a fast test for fuel stability.
