Abstract

Correlations between flash points and vapor pressures at 25 [deg]C for pure organic compounds were investigated. It was found that classification of organic compounds according to their chemical-structural characteristics (e.g., functional groups) was necessary for the correlation study. Under this classification, linearity seems to be the most appropriate correlation to explain the relationship between the inverse of flash points ([deg]K) and the logarithm of vapor pressures (mm Hg) at 25[deg]C for pure organic compounds. A test study to evaluate the validity of a regression line as an estimation of an unknown flash point from a known vapor pressure was carried out with a data set containing 31 alkanes and aromatics; 55% of the flash points were predicted within +/-5[deg]Cand89% were within +/-10[deg]C. Within limits of +/- 5 to 10[deg]C the procedure is useful but should be improved.
