Estimation of lower flammability limit temperature of chemical compounds using a corresponding state method

This work aims at presenting a corresponding state method to estimate the lower flammability limit temperature of 1480 organic compounds from 77 chemical families. The parameters of this model include the critical temperature, critical pressure, acentric factor, and normal boiling temperature of the compounds. The obtained average absolute relative deviation of the results (1.6, 1.6 and 1.8% for training, optimization and prediction sets, respectively) demonstrates improved accuracy of the presented model with respect to previously proposed methods.
