Résumé

HFO-1123 is a substance with a very low GWP and it is expected to become a new refrigerant in refrigeration and air-conditioning equipment. However, it is known that HFO-1123 may undergo a disproportionation reaction under high-temperature and high-pressure conditions. This reaction is a self-decomposition reaction accompanied by severe pressure and temperature rises. In this study, we investigate the effects of mixed substances of varying constituents and concentrations on the suppression of disproportionation reactions at various temperatures and pressures. Using a metallic pressure vessel having a volume of 0.65 L, energy is inputted by adding molten molybdenum into pure HFO-1123 as well as into a mixture containing HFO-1123 and other substances under various temperature and pressure conditions. The changes in pressure and temperature are then measured. Based on the obtained experimental data, the effects of the mixed substances on the reaction are evaluated.
