A solution of the initial methane soot in acetonitrile and solid products of its reaction with oxidizing reagents O3 and NO2 is analyzed using high-resolution mass spectrometry with an electrospray ion source and gas chromatography (GC)–mass spectrometry (MS) with electron ionization. It is established that the original soot contains a number of aromatic compounds, including polycyclic compounds, which are completely consumed in the reaction with these oxidizing agents. Compounds from the paraffin class remain inert with respect to NO2 and O3. The products of the ozonization of prenitrated soot are the same as those of simple ozonation. The number of ozonation products is much higher than similar nitration products. This is the reason for the reactivity of nitrated soot with respect to the ozone uptake.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181323955472">С использованием проточного реактора с подвижной вставкой и масс-спектрометрическим контролем газового состава была проведена обработка образцов метановой сажи реагентами O<sub>3</sub> и NO<sub>2</sub> до момента полного прекращения их захвата поверхностью. Анализ растворов исходной метановой сажи и твердых продуктов ее реакции с окисляющими реагентами O<sub>3</sub> и NO<sub>2</sub> в ацетонитриле проводился с использованием масс-спектрометрии высокого разрешения с электроспрейным ионным источником и газовой хроматографии–масс-спектрометрии с электронной ионизацией. Установлено, что исходная сажа содержит ряд ароматических соединений, включая и полициклические, которые полностью расходуются в реакции с этими окислителями. Соединения из класса парафинов остаются инертными по отношению к NO<sub>2</sub> и О<sub>3</sub>. В качественном отношении продукты нитрования и озонирования одинаковы как по своему составу, так и по содержанию основных функциональных групп. Количество продуктов озонирования значительно больше аналогичных продуктов нитрования. Это является причиной высокой реакционной способности нитрованной сажи по отношению к захвату озона.</p></trans-abstract><kwd-group xml:lang="en"><kwd>tropospheric chemistry</kwd><kwd>O3</kwd><kwd>nitrogen dioxide</kwd><kwd>NO2</kwd><kwd>soot</kwd><kwd>solid reaction products</kwd><kwd>mass spectrometry</kwd><kwd>gas chromatography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>химия тропосферы,</kwd><kwd>диоксид азота</kwd><kwd>NO<sub>2</sub></kwd><kwd>сажа</kwd><kwd>твердые продукты реакции</kwd><kwd>масс-спектрометрия</kwd><kwd>газовая хроматография.</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Roberts-Semple D., Song F., Gao Yu. // Atmos.
