антрацита. С помощью ИК-спектроскопии изучена кинетика измельчения и проведен качественный и количественный анализ функциональных групп. Гранулометрический состав антрацита из провинции Нинся (Китай) соответствует кинетической модели n-го порядка, размер зерна достигает 42 нм через 24 ч. Интенсивность максимума ИК-спектров заметно увеличивается, а поверхностная активность порошка антрацита возрастает после ультратонкого измельчения. Пентазамещенные бензольные кольца ароматического водорода — доминирующие в неочищенном антраците, трис-замещенные бензольные кольца ароматического водорода становятся доминирующей формой после 24 ч сверхтонкого измельчения. Во время ультратонкого измельчения могут происходить циклизация алифатических цепей, дегидроароматизация циклопарафина, реакции замещения ориентирующих групп в ароматических кольцах и декарбоновые реакции бензольных колец. Необработанный антрацит показывает относительно высокую степень метаморфизма, при этом его частицы проявляют высокую активность и могут поглощать больше кислорода после ультратонкого измельчения, увеличивая обогащение кислородом. Группа CH в алифатических углеводородах ультратонкого антрацита в основном исчезает, а при ультратонком измельчении CH2 теряется легче, чем CH3. Кислородсодержащие функциональные группы в антраците изменяются или некоторые из их элементов вступают в реакцию с кислородом, что уменьшает количество свободных групп ОН на поверхности частиц антрацита. При ультратонком измельчении стабильность водородных связей оценивается как ОН… π&gt;ОН… ОН&gt;свободные группы ОН&gt;ОН… эфир&gt;ОН… N&gt;циклические тетрамеры ОН. Изменения указывают на то, что процесс ультратонкого измельчения антрацита также сопровождается химическими реакциями. Результаты служат справочным материалом и руководством для изучения изменений в молекулярной структуре ультратонкого антрацита и последующей глубокой обработки. В частности, наличие меркаптана -SH и FeS2 означает, что сера существует в антраците как в органических, так и в неорганических формах. Пик поглощения сверхмелкозернистого измельченного каолинита усиливается, указывая на диссоциацию минералов, и после измельчения они подвергаются воздействию большего количества примесей. </p></abstract><trans-abstract xml:lang="en"><p>Comminution is widely used in the deep processing of coal resources. Different chemical structures in coals can influence follow-up procedures significantly. A planetary ball mill was used as a comminution device, and its effects on the grain size and chemical structure of anthracite from Ningxia, China were studied. Comminution kinetics were studied and qualitative and quantitative analyses of functional groups were done by IR spectrometry. The results demonstrate that product size distribution of anthracite from Ningxia conformed to the n-order kinetic model and the grain size reached −42 nm after 24 h. The peak intensity of the IR spectra increased markedly, and the surface activity of anthracite powder was enhanced after ultrafine comminution. Penta-substituted benzene rings of aromatic hydrogen were the dominant group in raw anthracite, while tris-substituted benzene rings of aromatic hydrogen became the dominant form after 24 h of ultrafine comminution. During ultrafine comminution, cyclization of aliphatic chains, dehydroaromatization of cycloparaffin, substitution reactions of orienting groups on aromatic rings, and decarboxylic reactions of benzene rings might occur. Although raw anthracite shows a relatively high degree of metamorphism, its particles show stronger activity and can absorb more oxygen after ultrafine comminution, thus increasing oxygen enrichment. The CH in the aliphatic hydrocarbons of ultrafine anthracite basically disappeared, and CH2 was more easily lost than CH3 during ultrafine comminution. Oxygen-containing functional groups in anthracite were altered or some of their elements reacted with oxygen, which decreased the amount of free OH groups on anthracite particle surfaces. During ultrafine comminution, the stability of hydrogen bonds was ranked OH…π &gt; OH…OH &gt; free OH groups &gt; OH…ether &gt; OH…N &gt; cyclic OH tetramers. These changes indicate that the ultrafine anthracite comminution process is also accompanied with chemical reactions. The results provide a reference and guidance for exploring changes in the molecular structures of ultrafine anthracite and follow-up deep processing. In particular, the occurrence of mercaptan -SH and FeS2 implies that sulfur exists in anthracite in both organic and inorganic forms. The absorption peak of ultrafine pulverized kaolinite was intensified, indicating that minerals were dissociated and more impurities were exposed after comminution. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>антрацит</kwd><kwd>ИК-Фурье-спектроскопия</kwd><kwd>функциональные группы</kwd><kwd>сверхтонкое измельчение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anthracite</kwd><kwd>Fourier transform infrared spectroscopy</kwd><kwd>functional groups</kwd><kwd>ultrafine comminution</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">This work was supported by the National Natural Science Foundation of China (Grant No. 51374015), the National Natural Science Foundation of Anhui Province (Grant No. 1708085QE128), and the Foundation of State Key Laboratory of High-efficiency Utilization of Coal and Green Chemical Engineering (Grant No. 2021-K19).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">A.
