In order to determine the process conditions (duration and temperature of the reaction) under which the maximum possible yield of the target quaternary ammonium salts is achieved, the effect of the halide structure on the yield of tert-amines and their subsequent salts was evaluated. The study also aimed to establish the structural and spatial structure of the obtained carbo- and heterocyclic amines and salts based on them, as well as to evaluate the anticorrosive properties of the obtained products in a hydrogen sulfide medium.</p></sec><sec><title>   Methods</title><p>   Methods. The target compounds, such as tertiary amines and quaternary ammonium salts (QAS), were obtained by classical methods of organic synthesis consisting of alkylation and condensation of the corresponding amines of various structures. Preparation of QAS was carried out using a microwave system for organic synthesis via microwave activation on a Sineo device (China). The qualitative and quantitative composition of the reaction masses was determined using gas–liquid chromatography (Crystal 2000 hardware and software complex), while mass spectroscopy was carried out on a Chromatec-Crystal 5000M device with a NIST 2012 database). A Bruker AM-500 device having operating frequencies of 500 and 125 MHz was used to perform nuclear magnetic resonance spectroscopy.</p></sec><sec><title>   Results</title><p>   Results. Tertiary amines containing a cycloacetal or gem-dichlorocyclopropane fragment were obtained under thermal heating conditions. By carrying out their condensation in excess halides using microwave radiation, new quaternary ammonium salts were synthesized with a yield close to quantitative. Anticorrosive activity was estimated for the obtained cyclic compounds. 4-Allyl-4-[2-(1,3-dioxolan-2-yl)-ethyl]morpholinium chloride was determined to have the maximum protective effect in a hydrogen sulfide medium with a protection level of 91 %.</p></sec><sec><title>   Conclusions</title><p>   Conclusions. Tertiary amines containing a cycloacetal or gem-dichlorocyclopropane fragment were obtained under the proposed conditions. Such substances are in demand as intermediates in the synthesis of quaternary ammonium salts having anticorrosive activity.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>   Цели</title><p>   Цели. Синтезировать третичные амины — производные морфолина и пиперидина, содержащие 1,3-диоксолановый или гем-дихлорциклопропановый фрагмент, а также четвертичные аммониевые соли на их основе. Оценить влияние строения галогенидов на выход трет-аминов и их последующих солей. Определить условия (длительность и температуру реакции) проведения процесса, при которых достигается максимально возможный выход целевых четвертичных аммониевых солей. Установить структурное и пространственное строение полученных карбо- и гетероциклических аминов и солей на их основе, а также оценить антикоррозионные свойства полученных продуктов в сероводородной среде.</p></sec><sec><title>   Методы</title><p>   Методы. Целевые соединения, такие как третичные амины и четвертичные аммониевые соли (ЧАС), были получены классическими способами органического синтеза — алкилированием и конденсацией соответствующих аминов различного строения. Получение ЧАС было осуществлено с использованием микроволновой системы для проведения органических синтезов методом микроволной активации на приборе «Sineo» (Китай). Качественный и количественный состав реакционных масс были определены газожидкостной хроматографией (на аппаратно-программном комплексе «Кристалл 2000»), масс-спектроскопией (на приборе «Хроматэк-Кристалл 5000М» с базой NIST 2012) и спектроскопией ядерного магнитного резонанса (на приборе «Bruker AM-500» с рабочими частотами 500 и 125 МГц).</p></sec><sec><title>   Результаты</title><p>   Результаты. В условиях термического нагрева получены третичные амины, содержащие циклоацетальный или гем-дихлорциклопропановый фрагменты, конденсация которых в избытке галогенидов с использованием микроволнового излучения позволила синтезировать новые четвертичные аммониевые соли с выходом, близким к количественному. Для полученных циклических соединений была оценена антикоррозионная активность. Определено, что максимальным защитным эффектом в сероводородной среде обладает 4-аллил-4-[2-(1,3-диоксолан-2-ил)этил]морфолиниум хлорид, который имеет степень защиты, равную 91 %.</p></sec><sec><title>   Выводы</title><p>   Выводы. В предложенных условиях были получены третичные амины, содержащие циклоацетальный или гем-дихлорциклопропановый фрагменты. Третичные амины служат промежуточными продуктами в синтезе четвертичных аммониевых солей, обладающих антикоррозионной активностью.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>алкилирование</kwd><kwd>микроволновое излучение</kwd><kwd>четвертичная аммониевая соль</kwd><kwd>коррозия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alkylation</kwd><kwd>microwave radiation</kwd><kwd>quaternary ammonium salt</kwd><kwd>corrosion</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации в сфере научной деятельности, номер для публикаций FEUR – 2022-0007 «Нефтехимические реагенты, масла и материалы для теплоэнергетики»</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the State Assignment of the Ministry of Science and Higher Education of the Russian Federation in the field of scientific activity, publication No. FEUR – 2022-0007“Petrochemical reagents, oils, and materials for thermal power engineering”</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">Waiker D.K., Verma A., Akhilesh G.T., Singh N., Roy A., Dilnashin H., Tiwari V., Trigun S.K., Singh S.P., Krishnamurthy S., Lama P., Davisson V.J., Shrivastava S.K.
