Abstract

For the reliability of the combustible properties of arylic acid, this study was investigated the explosion limits of acrylic acid in the reference data. The flash points and AITs(auto-ignition temperatures) by ignition delay time were experimented. The lower flash points of acrylic acid by using Setaflash and Pensky-Martens closed-cup testers were experimented in $48^{\circ}C$ and $51^{\circ}C$, respectively. The lower flash points of arylic acid by using Tag and Cleveland open cup testers were experimented in $56^{\circ}C$. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 tester for acrylic acid. The AIT of acrylic acid was experimented as $417^{\circ}C$. The lower explosion limit(LEL) and the upper explosion limit(UEL) by the measured the lower flash point and the upper flash point of acrylic acid were calculated as 2.2 Vol% and 7.9 Vol%, respectively.

아크릴릭산 연소특성치의 신뢰도를 살펴보기 위해, 폭발한계에 대해서는 문헌을 통해 고찰하였고, 인화점과 발화지연시간에 의한 발화온도를 측정하였다. 그 결과, Setaflash와 Pensky-Martens 밀폐식 장치에 의한 아크릴릭산의 하부인화점은 $48^{\circ}C$와 $51^{\circ}C$로 측정되었으며, Tag와 Cleveland 개방식에서는 $56^{\circ}C$로 측정되었다. ASTM E659 장치를 사용하여 자연발화온도와 발화지연시간을 측정하였고, 아크릴릭산의 최소자연발화온도는 $417^{\circ}C$로 측정되었다. 측정된 하부인화점과 상부인화점에 의한 폭발하한계는 2.2 Vol%, 상한계는 7.9 Vol%로 계산되었다.
