Abstract
The Flash Point is one of the most important combustible properties used to determine the potential for fire and explosion hazards of chemical materials. An accurate knowledge of the flash point is important in developing appropriate preventive and control measures in industrial fire protection. The lower flash points for the Water + n-Propanol systems were measured by using Pensky-Martens closed cup tester. 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.
