식용 콩기름의 가열산화과정 초기에 형성되는 가장 중요한 중간생성체인 하이드로퍼로키사이드(hydroperoxide)의 생성기구대신 분해기구의 한 모델을 설정하였다. $100^{circ}C,;120^{circ}C,;150^{circ}C$와 $180^{circ}C$에서 120 ml/min의 공기주입하에 가열산화된 콩기름시료의 하이드로퍼로키사이드외 분해속도를 실험을 통하여 측정하고 위의 분해기구에 적용하여 분석, 검토하였다. 이상의 분석결과 하이드로퍼로키사이드 분해반응의 반응속도차수는 1차적이었음을 알 수 있었다. 또한 이상의 분해속도 측청치에서 산출한 하이드로퍼로키사이드의 해리에너지는 15.876 Kcal/g mol이었다.
In the present study, a tentative mechanism for the decomposition of the hydroperoxide formed during the thermal oxidation of an edible soybean oil was proposed. The soybean oil was thermally oxidized at $120^{circ}C$ for 7 hrs with air injection at a rate of 120 ml/min. Through kinetic studies of the decomposition process based on the tentative mechanism and the actual experimental data obtained from the hydroperoxide decomposition at 100, 120, 150 and $180^{circ}C$, it was found that the reaction order of the hydroperoxide decomposition in these conditions was of first order. It was also estimated that the dissociation energy for the hydroperoxide in the same conditions was 15.876 kcal/g. mol.
