Abstract
For the safe handling of n-hexadecane, the lower flash points and the upper flash point, fire point, AITs(auto-ignition temperatures) by ignition delay time were experimented. Also lower and upper explosion limits by using measured the lower and upper flash points for n-hexadecane were calculated. The lower flash points of n-hexadecane by using the Setaflash and the Pensky-Martens closed testers were measured <TEX>$128^{\circ}C$</TEX> and <TEX>$126^{\circ}C$</TEX>, respectively. The lower flash points of the Tag and the Cleveland open cup testers were measured <TEX>$136^{\circ}C$</TEX> and <TEX>$132^{\circ}C$</TEX>, respectively. The fire points of the Tag and the Cleveland open cup testers were measured <TEX>$144^{\circ}C$</TEX>. respectively. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 apparatus for n-hexadecane. The experimental AIT of n-hexadecane was <TEX>$200^{\circ}C$</TEX>. The calculated lower and upper explosion limit by using measured lower <TEX>$128^{\circ}C$</TEX> and upper flash point <TEX>$180^{\circ}C$</TEX> for n-hexadecane were 0.42 Vol.% and 4.70 Vol.%.
