EFFECT OF CARBOXYLIC ACIDS ON OXIDABILITY OF JET FUELS

VLIYANIE KARBONOVYKH KISLOT NA OKISLYAEMOST' REAKTIVNYKH TOPLIV

The kinetics of oxidation regarding oxygen absorption and changes in the oxidation potential (OP) at the temperatures of 110-150 degree C of the following substances are studied: 1) carboxylic acids contained in jet fuels; 2) straight-run fuel T-1 from which oxygen-containing compounds have been removed; 3) hydropurified fuel T-7; 4) fuels T-1 and T-7 with appropriate additions of carboxylic acids. It is found that carboxylic acids contained in fuels are resistant to oxidation. At the temperature of 150 degree C, only 7-8% of carboxylic acids are oxidized. From monoacids they are converted to diacids. Carboxylic acids present in jet fuels as products of hydrocarbon self-oxidation (0.015%wt.), and even more so as a possible wear-resisting additive (0.003% wt.), do not have any noticeable effect on the oxidability of fuels.
