Measurement and Prediction of the Flash Point for the Flammable Binary Mixtures using Tag Open-Cup Apparatus

摘要

The flash point is one of the most important combustible properties used to determine the potential for fire and explosion hazards of industrial material.An accurate knowledge of the flash point is important in developing appropriate preventive and control measures in industrial fire protection.The flash points for the n-butanol+n-propionic acid and n-propanol+n-propionic acid systems were measured by using Tag open-cup apparatus(ASTM D 1310-86).The experimental data were compared with the values calculated by the laws of Raoult and van Laar equation.The calculated values based on the van Laar equation were found to be better than those based on the Raoult's law.
