Prediction and measurement of the lower flash points for flammable binary solutions by using a setaflash closed cup tester

Abstract

The flash point is one of the most important physical properties used to determine the potential for fire and explosion hazards of industrial materials. The purpose of this study was to measure and predict the lower flash points for the binary mixtures to aid in evaluating the safety of flammable liquid mixtures. The lower flash points for the flammable binary systems, n-hexanol+propionic acid, n-butyric acid+m-xylene and n-pentanol+n-butanol, were measured by Setaflash closed cup tester. The experimentally derived data were correlated with the Wilson and UNIQUAC (UNIversal QUuasi Chemical) equations using the binary interaction parameters. Both equations correlated with a good accuracy.
