아니솔의 연소특성치의 측정에 의한 MSDS의 적정성

Appropriateness of MSDS by Means of the Measurement of Combustible Properties of Anisole

아니솔의 안전한 취급을 위해, 폭발한계는 문헌을 통해 고찰하였고, 인화점과 발화지연시간에 의한 발화온도를 측정하였다. 그 결과, 밀폐식 장치에 의한 아니솔의 하부인화점은 <TEX>$39^{\circ}C$</TEX>와 <TEX>$42^{\circ}C$</TEX>로 측정되었으며, 개방식에서는 <TEX>$50^{\circ}C$</TEX>와 <TEX>$54^{\circ}C$</TEX>로 측정되었다. ASTM E659 장치를 사용하여 자연발화온도와 발화지연시간을 측정하였고, 아니솔의 최소자연발화온도는 <TEX>$390^{\circ}C$</TEX>로 측정되었다. 측정된 하부인화점에 의한 폭발하한계는 1.07 Vol%로 계산되었다.

For the safe handling of anisole, this study was investigated the explosion limits of anisole in the reference data. The flash points and auto-ignition temperatures (AITs) by ignition delay time were experimented. The lower flash points of Anisole by using closed-cup tester were experimented in <TEX>$39^{\circ}C$</TEX> and <TEX>$42^{\circ}C$</TEX>. The lower flash points of Anisole by using open cup tester were experimented in <TEX>$50^{\circ}C$</TEX> and <TEX>$54^{\circ}C$</TEX>. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 tester for Anisole. The AIT of Anisole was experimented as <TEX>$390^{\circ}C$</TEX>. The lower explosion limit (LEL) by the measured the lower flash point for Anisole were calculated as 1.07 Vol%.
