Determination of target products and byproducts is necessary for the quality control of phthalonitrile monomer synthesis as well as production scaling and performing related kinetic studies. High-performance liquid chromatography (HPLC) is a simple and affordable method for quantitative chemical analysis, which also verifies the quality of raw materials. The objective of this study was to develop an HPLC technique for determining the composition of the reaction mixture in the synthesis of 1,3-bis(3,4-dicyanophenoxy)benzene (DPB).</p></sec><sec><title>Methods</title><p>Methods. Reversed-phase HPLC was used to quantitatively analyze the reaction mixture.</p></sec><sec><title>Results</title><p>Results. A simple and rapid method for the quantitative HPLC analysis of phthalonitrile monomers and their mixtures with reagents was developed. Reaction times and the accumulation of byproducts were also studied.</p></sec><sec><title>Conclusions</title><p>Conclusions. The successful performance of the developed technique allows us to recommend it for practical applications. The results obtained for reactors of different sizes have good convergence, and DPB synthesis was successfully scaled up to intermediate scale equipment.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цели</title><p>Цели. Для аналитического контроля производства фталонитрильных мономеров, изучения масштабирования технологии их получения и проведения кинетических исследований актуальна задача по разработке способа определения концентрации целевого и побочных продуктов в присутствии реагентов. Наиболее простым и доступным методом количественного анализа рассматриваемых соединений является высокоэффективная жидкостная хроматография (ВЭЖХ), позволяющая также проводить верификацию сырья и контроль качества готовой продукции. Цель данной работы заключалась в разработке методики количественного анализа компонентов реакционной смеси при синтезе 1,3-бис(3,4-дицианофенокси)бензола (ДБФ) методом ВЭЖХ.</p></sec><sec><title>Методы</title><p>Методы. Для количественного анализа компонентов реакционной смеси использовали метод ВЭЖХ в обращенно-фазовом режиме.</p></sec><sec><title>Результаты</title><p>Результаты. Разработана простая и быстрая методика количественного анализа фталонитрильных мономеров и их смесей с реагентами методом ВЭЖХ. По данным исследования конверсии компонентов реакционной смеси сделан вывод о продолжительности реакции и накоплении побочных продуктов.</p></sec><sec><title>Выводы</title><p>Выводы. Успешная апробация позволяет рекомендовать разработанную методику для применения в аналитической практике. Результаты, полученные при переходе от реакции в колбе к реактору объемом 15 л, характеризуются хорошей сходимостью. Синтез ДФБ успешно масштабируется на оборудование промежуточного масштаба.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>1</kwd><kwd>3-бис(3</kwd><kwd>4-дицианофенокси)бензол</kwd><kwd>высокоэффективная жидкостная хроматография</kwd><kwd>количественный анализ</kwd><kwd>масштабирование</kwd><kwd>фталонитрильные связующие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>1</kwd><kwd>3-bis(3</kwd><kwd>4-dicyanophenoxy)benzene</kwd><kwd>high-performance liquid chromatography</kwd><kwd>quantitative analysis</kwd><kwd>scaling up</kwd><kwd>phthalonitrile resins</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Химического факультета МГУ им.
