摘要：

In order to study and predict the auto-ignition temperature (AIT) of binary flammable liquid mixtures, the AITs of 168 binary flammable liquid mixtures composed of different components and volume ratios were measured by AITTA 551 auto-ignition temperature tester. An AIT prediction model of binary liquid mixtures was proposed on the basis of pure substance AIT prediction model according to the principle of group contribution method. The detailed model was established by multiple nonlinear regression method (MNR). The mean absolute errors of training set and test set were 20.1042℃ and 25.9045℃, respectively, corresponding to the mean absolute percentage errors of 5.18% and 7.25%. The predicted AITs were in good agreement with the experimental data. The AIT prediction of alkane-alkane and alcohol-alcohol systems was the best. For the mixed system containing benzene ring, the prediction ability of the model was mediocre. An effective method was provided for predicting the AIT of flammable liquid mixtures. ©, 2015, Science Press. All right reserved.
