Conclusions:

Autoignition temperature (AIT) is the lowest temperature at which the substance will produce hot-flame ignition in air at atmospheric pressure without the aid of an external energy sources such as spark or flame.

For some compounds in each class, the number of carbon and hydrogen atoms is sufficient for predicting the autoignition of the compound without considering the other structural parameters. However, elemental composition has the main contribution in estimating autoignition, which can be corrected on the basis of the presence of some molecular structure parameters. For various n-alkanes, methane has the highest AIT,and decreasing autoignition is observed up to pentane.
Meanwhile, the AIT (autoignition temperatures (AITs)) of heptane to high alkanes, i.e., up to nonacosane, is low and less than 515 K. Alkanes with more than two branching chain also have relatively high AIT, which are close to each other. Furthermore, changing the location of the alkyl groups on the longest continuous chain of carbon atoms has minor effect. The autoignition of other saturated alkanes are between two extremes. For saturated cycloalkanes without substituents from cyclopropane to cyclopentane, the AIT decreases sharply. Unbranched cyclohexane has low AIT (i.e., 518 K), and AITs of higher.

For mixtures of different hydrocarbon fuels, it is possible to calculate the AIT from a comprehensive analysis of the individual components in them and their contribution to overall autoignition quality. The present method can be used to predict the AITs of different classes of hydrocarbons containing alkanes, alkenes, cycloalkanes, cycloalkenes,
alkynes, and aromatics. The number of carbon and hydrogen atoms as well as two functions FSH and FBH in Eq. (1) can be easily found from molecular structures of
hydrocarbons. As compared to three of the best available SGC methods, i.e., Abahri [8], Albahri and George [9], and Chen et al. [13], the present model provides more reliable
results and can be easily applied for different types of hydrocarbons without any difficulty.

Conseidering the prediction the test material has been determined not to have a relative self-ignition temperature below its melting temperature.

Executive summary:

Conseidering the prediction the test material has been determined not to have a relative self-ignition temperature below its melting temperature.
