Все они продемонстрировали более высокую селективность (~ 40 %) по целевому продукту – 2-LAB (2-линейному алкилбензолу), чем обычный AlCl3-катализатор (~ 32 %). Помимо гомогенных катализаторов, на основе ионной жидкости был синтезирован нанесенный (SG–N+(C2H5)3–Al2Cl7–), селективность которого по 2-LAB оказалась еще выше (~ 45 %). Более того, по возможности повторного использования он существенно превосходит гомогенные катализаторы. Нанесенный катализатор был охарактеризован методами ИК-Фурье-спектроскопии, MAS-ЯМР и СЭМ. Кислотность нанесенного ионно-жидкого катализатора характеризовали функцией Гаммета (Ho). ИК-спектр адсорбированного на катализаторе (SG–N+(C2H5)3–Al2Cl7–) пиридина показал наличие обычных кислотных центров Брёнстеда и Льюиса. В спектре 27Al MAS-ЯМР наблюдалась полоса при ~ 6,987 ppm, характерная для шестикоординированных частиц Al. С использованием MATLAB 7.4.0 был разработан нелинейный алгоритм оптимизации с целью определения кинетических параметров для реакции алкилирования бензола 1-додеценом в присутствии катализатора (SG–N+(C2H5)3–Al2Cl7–). Концентрации продуктов, рассчитанные по данной модели, хорошо согласуются с экспериментальными значениями (относительная погрешность ~ 1,5 %).</p></abstract><trans-abstract xml:lang="en"><p>AlCl3 based homogeneous ionic liquids such as 1-butyl 3-methyl imidazolium chloroaluminate ([BMIm]+Al2Cl7–), 1-butyl 3-methylpyridinum chloroaluminate ([BMPy]+Al2Cl7–) and triethylamine hydrochloride chloroaluminate (Et3NHCl-AlCl3) were prepared to study the benzene alkylation with 1-dodecene. All homogeneous ionic liquid catalysts have shown higher selectivity (~ 40 %) for desired 2-LAB (2-linear alkylbenzene), than the conventional AlCl3 catalyst (~ 32 %). Apart from the homogeneous catalysts, one supported ionic liquid catalyst (SG-N+(C2H5)3-Al2Cl7–), was also synthesized. The supported ionic liquid catalyst showed further increased selectivity of the 2-LAB (~ 45 %). Moreover, the reusability of SG-N+(C2H5)3-Al2Cl7– catalyst was much higher than the homogeneous ionic liquid catalysts. The supported ionic liquid catalyst was characterized by various techniques such as FT-IR, MAS-NMR and Scanning Electron Microscopy (SEM). Hammett acidity function (Ho) was used to determine the acidity of supported ionic liquid catalyst. The pyridine adsorbed FT-IR spectra of (SG-N+(C2H5)3-Al2Cl7–) catalyst showed presence of common Brönsted-Lewis acidic sites. The 27Al MAS-NMR of (SG-N+(C2H5)3-Al2Cl7–) catalyst showed a band at ~ 6,987 ppm, which is attributed to 6-coordinated Al species. A nonlinear optimization algorithm was developed in MATLAB 7.4.0 to determine the kinetic parameters of the benzene alkylation with 1-dodecene in presence of (SG-N+(C2H5)3-Al2Cl7–) catalyst. The concentrations of the products predicted by model were found in good agreement with experiments (relative error ~ 1,5 %).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гомогенный катализатор на основе ионной жидкости</kwd><kwd>нанесенный катализатор на основе ионной жидкости</kwd><kwd>получение линейных алкилбензолов</kwd><kwd>кинетика алкилирования бензола 1-додеценом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>homogeneous ionic liquid catalyst</kwd><kwd>supported ionic liquid catalyst</kwd><kwd>production of linear alkylbenzenes</kwd><kwd>kinetic of the benzene alkylation with 1-dodecene</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sharrah M.L., Feighner G.C. // Industr.
