Abstract

In this study, combustion characteristics were measured by selecting di-n-buthylamine, which is widely used as an emulsifier, insecticide, additive, rubber vulcanization accelerator, corrosion inhibitor, and raw material for dye production. The flash point of the di-n-buthylamine was measured by Setaflash, Pensky-Martens, Tag, and Cleveland testers. And the AIT of the di-n-buthylamine was measured by ASTM 659E. The explosion limits of the di-n-buthylamine was calculated using the measured flash points by Setaflash tester. The flash point of the di-n-buthylamine by using Setaflash and Pensky-Martens closed-cup testers were experimented at 38 ℃ and 43 ℃, respectively. The flash points of the di-n-buthylamine by Tag and Cleveland open cup testers were experimented at 48 ℃. The AIT of the di-n-buthylamine was experimented at 247 ℃. The LEL and UEL calculated by using lower and upper flash points of Setaflash tester were calculated at 0.69 vol% and 7.7 vol%, respectively. The measurement of the flash point measurement and the calculation method of the explosion limit prediction presented in this study can be used to study the fire and explosion characteristics of the other combustible liquids.

본 연구에는 유화제, 살충제, 첨가제, 고무 가황 촉진제, 부식 억제제제 및 염료 생산의 원재료 등으로 다양하게 사용되고 있는 디노말부틸아민(di-n-buthylamine)을 선정하여 연소특성치를 측정하였다. 디노말부틸아민의 인화점은 밀폐식 Setaflash와 Pensky-Martens 그리고 개방식 Tag, Cleveland 장치로 측정하였고, 연소점은 개방식 장치를 이용하였다. 최소자연발화온도(AIT)는 ASTM 659E를 사용하였다. 그리고 디노말부틸아민의 폭발한계는 측정된 인화점을 이용하여 예측하였다. Setaflash와 Pensky-Martens에 의한 인화점은 38 ℃와 43 ℃로 측정되었고, Tag와 Cleveland는 각각 48로 동일하게 측정되었다. 디노말부틸아민의 AIT는 247 ℃로 측정되었다. Setaflash에서 측정된 인화점에 의한 폭발하한계는 0.69 vol%, 상한계는 7.7 vol%로 계산되었다. 본 연구에서 제시한 인화점 측정과 폭발한계의 예측 방법은 다른 가연성액체의 화재 및 폭발특성 연구에 활용이 가능하다.
