Показано, что изменения скорости охлаждения и концентрации насыщенных растворов оказывают влияние на получение образцов субстанции модафинила, имеющих отличия дифрактометрических характеристик. Причем скорость охлаждения практически не влияет на выход кристаллического продукта, который находится в зависимости от степени насыщения кристаллизационных растворов. Установлено, что I полиморфная форма модафинила может быть получена из растворов модафинила с концентрацией в диапазоне 0,34–0,44 М при медленном охлаждении растворов, преимущественно с градиентом температур 5–10 ºС/ч до температуры (5 ± 2) ºС. Увеличение скорости охлаждения насыщенных растворов и их концентрация &gt;0,44 М приводит к получению смешанных полиморфных форм кристаллов модафинила.</p></abstract><trans-abstract xml:lang="en"><p>The effect of the crystallization conditions of modafinil from its methanol solutions on the polymorphic state of the resulting substance was studied using the X-ray powder diffraction method. It is shown that changes in the cooling rate and the concentration of saturated solutions have an effect on obtaining samples of the modafinil substance with differences in diffractometric characteristics. Moreover, the cooling rate practically does not affect the yield of the crystalline product, which depends on the degree of saturation of crystallization solutions. It was found that the I polymorphic form of modafinil can be obtained from modafinil solutions with a concentration in the range of 0.34–0.44 M with slow cooling of solutions, mainly with a temperature gradient of 5–10 °C/hour to a temperature of 5 ± 2 °C. An increase in the cooling rate of saturated solutions and their concentration &gt;0.44 M leads to the production of mixed polymorphic forms of modafinil crystals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модафинил</kwd><kwd>полиморфизм</kwd><kwd>субстанция</kwd><kwd>кристаллизация</kwd><kwd>порошковая рентгеновская дифракция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>modafinil</kwd><kwd>polymorphism</kwd><kwd>substance</kwd><kwd>crystallization</kwd><kwd>X-ray powder diffraction</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">Леонидов, Н.
