In this work, fire and explosion of DOTP(Dioctyl terephthalate) in batch proess has been studied. To evaluate the ignition possibility of powder was carried out to SEM(Scannig Electron Microscope), PSA(Par -ticle Size Analysis) and TGA (Thermo Gravimetric Analysis). Static electricity was measured in the environment similar to the accident scene, and compared it with the minimum ignition energy of terephthalic acid and octanol. As a result of the analysis, terephthalic acid particles were observed in various sizes of 0.19㎛~82.5㎛ and there was almost no weight loss (0.0001% reduction) even on 200℃. In addition, when the materials were added in the batch reactor, the generated static electricity was measured by 1.25mJ and the minimum ignition energy of terephthalic acid was measured at 10mJ~30mJ. Therefore it was found that fire and explosion was caused by initial ignition in the octanol vapor rather than terephthalic acid dust.
