Measurement and calculation of flash point of binary aqueous–organic and organic–organic solutions

Flash point for binary systems, pentan-1-ol + water, cyclohexanone + water, pentan-1-ol + cyclohexanone, pentan-1-ol + 1,2,3,4-tetrahydronaphthalene, were measured using the tag close cup apparatus by equilibrium test method. First two systems were partially miscible and the other two were completely miscible. s study attempt has been made to extend Liaw et al. algorithm for calculation of the flash point of both miscible and partial miscible mixtures. The proposed algorithm was evaluated with experimental data for both miscible and partial miscible mixtures. The results show good compatibility for both aqueous–organic and organic–organic solutions flash point calculation.
