This study describes a new approach to obtain para-tert-butylcumene by alkylation of cumene with isobutylene in the presence of catalysts, such as Amberlyst 36 Dry, KU-2-8, aluminum chloride, and tert-butyl alcohol and concentrated sulfuric acid.</p></sec><sec><title>Methods</title><p>Methods. To determine the qualitative and quantitative composition of the compounds and reaction masses, the following analysis methods were used: gas–liquid chromatography (on the Kristall 2000M hardware-software complex), chromatomass spectrometry on an Agilent 6850 instrument equipped with an Agilent 19091S-433E capillary column (30 m × 250 μm × 0.25 μm), and nuclear magnetic resonance spectroscopy (on a Bruker DRX 400 instrument with an operating frequency of 400 MHz).</p></sec><sec><title>Results</title><p>Results. A significant quantity of meta-tert-butylcumene was obtained by the alkylation of cumene with isobutylene using several catalysts, along with para-tert-butylcumene. This study also showed that the use of the catalysts Amberlyst 36 Dry and KU-2-8 during alkylation in a closed system (autoclave) led to the formation of isobutylene oligomers, often in quantity greater than the target reaction product. Simultaneously, the alkylation of cumene with tert-butyl alcohol in the presence of concentrated sulfuric acid enabled the obtainment of only one isomer, para-tertbutylcumene, which is essential for the further production of high-purity para-tert-butyl phenol.</p></sec><sec><title>Conclusions</title><p>Conclusions. Sulfuric acid alkylation of cumene with tert-butyl alcohol enabled the obtainment of an individual para-isomer of tert-butylcumene with a yield of 87–89% for the loaded tert-butyl-alcohol with a cumene conversion of ~30%.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цели</title><p>Цели. В статье рассматривается возможность получения пара-трет-бутилкумола алкилированием кумола изобутиленом в присутствии таких катализаторов, как Amberlyst 36 Dry, КУ-2-8, хлористый алюминий, и трет-бутиловым спиртом в присутствии концентрированной серной кислоты.</p></sec><sec><title>Методы</title><p>Методы. Для определения качественного и количественного состава веществ и реакционных масс использованы следующие методы анализа: газожидкостная хроматография (на аппаратно-программном комплексе «Кристалл 2000М»), хроматомасс-спектрометрия (на приборе Agilent 6850, оснащенном капиллярной колонкой Agilent 19091S-433E (30 м × 250 мкм × 0.25 мкм) и спектроскопия ядерного магнитного резонанса (на приборе «Bruker DRX 400» с рабочими частотами 400 МГц).</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что в процессе алкилирования кумола изобутиленом с использованием перечисленных катализаторов наряду с пара-трет-бутилкумолом образуется значительное количество мета-трет-бутилкумола. Также исследования показали, что применение катализаторов Amberlyst 36 Dry и КУ-2-8 при алкилировании в замкнутой системе (автоклав) приводит к образованию олигомеров изобутилена, количество которых многократно преобладает над целевым продуктом реакции. В то же время установлено, что алкилирование кумола трет-бутиловым спиртом в присутствии концентрированной серной кислоты позволяет получать только один изомер – пара-трет-бутилкумол, что имеет важное практическое значение для дальнейшего получения пара-трет-бутилфенола с высокой степенью чистоты.</p></sec><sec><title>Выводы</title><p>Выводы. Сернокислотное алкилирование кумола трет-бутиловым спиртом позволяет получить индивидуальный пара-изомер трет-бутилкумола с выходом 87–89% на загруженный трет-бутиловый спирт при конверсии кумола около 30%.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пара-трет-бутилкумол</kwd><kwd>изобутилен</kwd><kwd>трет-бутиловый спирт</kwd><kwd>алкилирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>para-tert-butylcumene</kwd><kwd>isobutylene</kwd><kwd>tert-butyl alcohol</kwd><kwd>alkylation</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">Курганова Е.А., Сапунов В.Н., Кошель Г.Н., Фролов А.С.
