Correlation and Calculation of the Flash Points of Organic Compounds

Correlation was investigated between the flash point and normal boiling point of organic compound. It was found out there was a good linear relation between flash point T f and normal boiling point T b, T f = 33 176 + 0 67465 T b and a universal method was developed that can be used to calculate the flash point of organic compound from the data of boiling point. The calculated results showed that the calculated flash points agreed with the experiment data satisfactorily, and the average relative percent error was 3 75% for 1457 flash data points. Not only can the method proposed in this paper reveal the quantitative relation between flash point and normal boiling point, but can be used to predict the flash points of organic compounds for chemical engineering.
