Outline of Final Research Achievements

Tetrafluoroethylene (TFE), which a raw material monomer of polytetrafluoro- ethylene (Teflon), has extremely high reactivity, and explosion accidents have repeatedly occurred in their actual chemical plants. TFE explosion is caused by autolysis reaction even without oxygen, but detailed reaction mechanism of TFE explosion is not clear yet. In the present study, a highly reliable reaction model for TFE self-decomposition explosion was constructed as that can predict and prevent explosion and fire at the time of storage and transportation of TFE, so that the reac- tion model was experimentally evaluated.
