Measurement and estimation of the lower flash points for the flammable binary systems using a Tag open cup tester

Lower flash points for flammable binary systems, ethylbenzene+n-propanol, n-propionic acid+ethylbenzene and n-propionic acid+o-xylene, were measured by Tag open cup tester. These binary solutions exhibited the minimum flash point behavior, which leads to a minimum on the flash point vs composition curve. The experimental data were compared with the values calculated by the flash point prediction models based on the van Laar and Wilson equations. As can be seen from the A.A.D., the calculated values based on the Wilson equation were found to be better than those based on the van Laar equation.
