Propionic Anhydride의 연소특성치의 측정 및 예측

다국어 초록 (Multilingual Abstract)

For the safe handling of Propionic Anhydride being used in various ways in the chemical industry, the flash point and the autoignition temperature(AIT) of Propionic Anhydride was experimented. And, the lower explosion limit of propionic anhydride was calculated by using the lower flash point obtained in the experiment. The flash points of propionic anhydride by using the Setaflash and Pensky-Martens closed-cup testers measured 60 ℃ and 61 ℃, respectively. The flash points of propionic anhydride by using the Tag and Cleveland open cup testers are measured 67 ℃ and 73 ℃. The AIT of propionic anhydride by ASTM 659E tester was measured as 280 ℃. The lower explosion limit by the measured flash point 60 ℃ was calculated as 1.37 Vol.%. It was possible to predict lower explosion limit by using the experimental flash point or flash point in the literature.
