Abstract

In order to examine the explosion risk of 2-ethylhexanoic acid, we experimentally studied the explosion limit, explosion pressure, and rate of increase of the explosion pressure at different oxygen concentrations. The lower explosion limit was 3.2% at a temperature of $100^{\circ}C$, and the oxygen concentration was 40 to 70%. The upper explosion limit was 4.5% and the lower explosion limit was 4.0% at an oxygen concentration of 21%.The maximum explosion pressure of 2-ethylhexanoic acid was 1.4161 MPa at an oxygen concentration of 70%, and the rate of increase of the explosion pressure was 62.692 MPa/s at this concentration.

2-Ethylhexanoic acid는 플라스틱의 충격보강제를 제조하는 물질로서 공정 중에 폭발위험성을 고찰하기 위하여 산소농도 변화에 따른 폭발범위, 폭발압력, 최대폭발압력상승속도를 실험한 결과 실험온도 $100^{\circ}C$에서, 산소농도 40~70%에서 폭발하한농도 3.2%를 구하였으며, 산소농도 21%에서 폭발하한 농도는 4.0%, 폭발상한 농도는 4.5%를 구하였다. 또한, 2-ethylhexanoic acid의 폭발압력은 산소농도 70%에서 1.4161 MPa의 최대폭발압력을 나타내었으며, 최대폭발압력상승속도를 구한 결과 산소농도 70%에서 62.692MPa/s를 구하였다.
