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 $60^{\circ}C$ and $61^{\circ}C$, respectively. The flash points of propionic anhydride by using the Tag and Cleveland open cup testers are measured $67^{\circ}C$ and $73^{\circ}C$. The AIT of propionic anhydride by ASTM 659E tester was measured as $280^{\circ}C$. The lower explosion limit by the measured flash point $60^{\circ}C$ 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.
