Abstract
For the safe handling of toluene, explosion limit at $25^{\circ}C$ and the temperature dependence of the explosion limits were investigated. And flash point and AIT (Autoignition Temperature) for toluene were experimented. By using the literature data, the lower and upper explosion limits of toluene recommended 1.13 vol% and 7.9 vol%, respectively. In this study, measured the lower and upper flash points of toluene by air-blowing tester were $5^{\circ}C$ and $40^{\circ}C$, respectively. And measured the upper flash points of toluene by Setaflash tester was $41.5^{\circ}C$. This study measured relationship between the AITs and the ignition delay times by using ASTM E659-78 apparatus for toluene, and the experimental AIT of toluene was $547^{\circ}C$. The new equations for predicting the temperature dependence of the explosion limits of toluene is proposed. The values calculated by the proposed equations were a good agreement with the literature data.
