Abstract
This research investigated the influence of binary solutions of benzene and methanol for their vapor flammability characteristics The different mixing ratios 100/0 75/25 50/50 25/75 and 0/100 vol samples were injected into a 20liter spherical explosion vessel under various initial temperatures 100 150 and 200°C to study their flammability behaviors According to the experimental results the flammability diagram of mixtures can be completely illustrated and combined with specific safetyrelated properties such as lower explosion limit LEL upper explosion limit UEL minimum oxygen concentration MOC maximum explosion overpressure Pmax and gas or vapor deflagration index Kg The experimental results showed that the UEL Pmax and Kg all increased with the temperature pressure and oxygen concentration whereas there was no significant variation on the part of LEL The results can provide specific information on fire and explosion hazards for related industries
