The autoignition temperatures(AIT) of solvent mixture is important index for the safe handling of flammable liquids which constitute the solvent mixtures. Therefore, the AITs of common pure chemical substances are widely reported, but very limited data are available for mixtures. This study, the toluene and 2-butnaol system which used mixture solution solvent was measured the AIT and ignition delay time by using ASTM E659 apparatus. The AITs of toluene and 2-butanol constituted binary system were $547^{\circ}C$ and $400^{\circ}C$, respectively. The experimental AIT of toluene and 2-butanol were a good agreement with the calculated AIT by the proposed equations with a few average absolute deviation(A.A.D.).
