To develop a method for the microfluidic synthesis of oligohexamethylene guanidine salts in a flow-type reactor and to evaluate its effectiveness in relation to the synthesis in a traditional capacitive reactor and compare the purities of products obtained by these methods.Methods. The synthesis of oligohexamethylene guanidine bihydrocarbonate (OHMG-BHC) was done using microfluidic hardware and the classical approach in volume. The purity and structure of the resulting product were confirmed by 13C NMR spectroscopy and high-performance liquid chromatography (HPLC).Results. The 13C NMR spectrum of OHMG-BHC in classical bulk synthesis demonstrates that the product is unbranched and contains additionally unidentifiable impurities, in contrast to the sample obtained by the microfluidic method. Furthermore, the HPLC analysis showed that the OHMG-BHC sample synthesized using microfluidic technology has a 1.5-fold lower content than the initial monomers.Conclusions. The advantage of synthesizing OHMG-BHC in a flow-type reactor compared to the traditional method of synthesis in volume is demonstrated since a product with a higher degree of purity is obtained.</p></abstract><trans-abstract xml:lang="ru"><p>Цели. Разработать методику микрофлюидного синтеза солей олигогексаметиленгуанидина в реакторе проточного типа и оценить ее эффективность по сравнению с синтезом в классическом емкостном реакторе, а также сравнить чистоту продуктов, полученных данными методами.Методы. Синтез олигогексаметиленгуанидина дигидрокарбоната (ОГМГ-ДГК) проводили с применением микрофлюидного аппаратного оснащения и классическим методом в объеме. Подтверждение чистоты и структуры полученного продукта осуществляли с помощью 13C ЯМР спектроскопии и высокоэффективной жидкостной хроматографии (ВЭЖХ).Результаты. Спектр 13C ЯМР ОГМГ-ДГК при классическом синтезе в объеме демонстрирует, что продукт является неразветвленным и содержит дополнительно неидентифицируемые примеси в отличие от образца, полученного микрофлюидным способом. Анализ методом ВЭЖХ показал, что образец ОГМГ-ДГК, синтезированный с помощью микрофлюидной технологии, имеет в 1.5 раза более низкое содержание исходных мономеров.Выводы. Синтез ОГМГ-ДГК в проточном реакторе имеет преимущество по сравнению с классическим способом синтеза в объеме, поскольку выдает продукт с более высокой степенью чистоты.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>резистентность к противомикробным препаратам</kwd><kwd>олигогексаметиленгуанидин</kwd><kwd>гидрокарбонат</kwd><kwd>микрофлюидный синтез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antimicrobial resistance</kwd><kwd>oligohexamethylene guanidine</kwd><kwd>bihydrocarbonate</kwd><kwd>microfluidic synthesis</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">Wanted: a reward for antibiotic development.
