Using experimental data available in the literature the auto-ignition temperature of saturated and unsaturated hydrocarbons with different molecular structures is analyzed. Based on modern research of hydrocarbons oxidation with different structures at high temperatures, the connection between chemical structure, bond strength in the molecule and radical mechanisms of oxidation processes with the auto-ignition temperature is shown. It is noted that the branching of molecules contributes to the temperature of self-ignition increase, that is, an increase in their composition of methyl groups, tertiary and quaternary carbon atoms located nearby in the carbon chain. Double and triple bonds, starting from C5, strengthen the molecule. The elongation of both the main chain and the chain of substituents reduces the auto-ignition temperature of the compound.
