The effects of temperature on the induction period and on the oxygen absorption rate of cetane oil(molecular weight 198, specific gravity at 20℃ 0.760) are measured under relatively mild oxidizing conditions (120-160℃, atmospheric pressure), principally by the static method. The activation energy of the reaction during the induction period derived from the temperature coefficients by the equation. log I = A/T - B ( I : induction period, hr, T : absolute temperature) is about 35 kcal. The rate of oxidation was well represented by the equation, <dV>/<dt> = 2kV^<1/2> (V : absorbed oxygen volume ml, t : duration of reaction, min) and the activation energy derived similarly with. this rate should be about 29 kcal. These two activation energies show the probable values as the energies of formation and of decomposition of the peroxides, respectively. The oxidation reaction of cetane oil may be proceed with the chain mechanism intiated by the formation of peroxides and aldehydes.
