   <abstract xml:lang="ru">
    <p>Проведен анализ влияния строения циклоалканов и ароматических углеводородов на температуру их самовоспламенения с использованием существующих в литературе экспериментальных данных. На базе современных исследований по кинетике самовоспламенения циклических неароматических углеводородов и аренов показана взаимосвязь структуры соединения, прочности связей в молекуле и особенностей радикальных механизмов процессов окисления с температурой самовоспламенения. Отмечено, что самую высокую температуру самовоспламенения, как правило, имеют незамещенные циклы. Повышению показателя у соединений с заместителями способствует увеличение в составе радикалов метильных групп и двойных связей, способных к сопряжению с бензольным кольцом. Заместители, расположенные в орто-положении, как и удлинение цепи алкильных радикалов, присоединенных к  кольцу, снижают температуру самовоспламенения. Полиядерные ароматические структуры имеют более низкую температуру самовоспламенения, чем  аналогичные по строению производные бензола.</p>

    <p>Using experimental data available in the literature the impact of the molecular structures of cycloalkanes and aromatic hydrocarbons on the auto-ignition temperature is analyzed. Based on contemporary studies of auto-ignition kinetic processes of cyclic nonaromatic and aromatic hydrocarbons, the connection between chemical structure, bond strength in the molecule and features of radical mechanisms of oxidation processes with the auto-ignition temperature is shown. It is noted that unsubstituted cycles usually have the highest auto-ignition temperature. The increase in the structure &#13;
of substituents the number of methyl groups and double bonds capable to conjugate with benzene ring contributes to an index increase. Alkyl side chains located in the ortho-position, as well as the elongation of the chain of alkyl radicals attached to the ring, reduce the auto-ignition temperature. Polycyclic aromatic structures have a lower auto-ignition temperature than structurally  similar benzene derivatives.</p>
