Трифлат висмута в России в настоящее время не производят, поэтому разработка технологии получения трифлата висмута является актуальной задачей. Трифлат висмута получали двумя способами - взаимодействием гидроксида висмута или оксида висмута с трифторметансульфоновой (трифликовой) кислотой. Получение трифлата висмута из гидроксида висмута является длительным процессом, который не протекает до конца и имеет выход не более 64 %. Оксид висмута, полученный термическим разложением гидроксида висмута, имеет несколько полиморфных модификаций. Нагревание проводили до 750 °С и охлаждали в течение 8 часов. Полученный таким образом γ-оксид висмута растворяется в трифликовой кислоте в течение 2 часов и образует растворы высокой концентрации. Определены значения растворимости трифлата висмута при различной кислотнотности раствора. Рентгенографическим исследованием. установлено, что образуется ноногидраттрифлата висмута - кристаллы игольчатой формы. α-фаза оксида висмута, полученная разложением гидроксида висмута при 450 °С, не растворялась в кислоте полностью. Процесс проводили в течение 4 часов, выход продукта 92 %. Образующиеся кристаллы бипирамидальной формы исследовали методом дифференциального термического анализа, который показал, что кристаллы представляют собой пентагидрат трифлата висмута, теряющий кристаллизационную воду в интервале температур 64–130 °С. До 320 °С вещество является термически устойчивым. При температуре 327 °С происходит плавление с разложением, что сопровождается образованием оксосульфатов висмута. По данным рентгенографической дифракции установлен состав образующихся фаз - Bi28O32(SO4)10 и Bi34.7O100S16. При дальнейшем нагревании до 380 °С разложение оксосульфатов висмута приводит к образованию устойчивой моноклинной модификации оксида висмута α-Bi2O3.</p></abstract><trans-abstract xml:lang="en"><p>Bismuth (III) trifluoromethanesulfonate, also known as bismuth triflate, is an economical, efficient, and environmentally friendly catalyst for the synthesis of organic products. Currently, bismuth triflate is not produced in Russia, so developing a technology for producing bismuth triflate is an important task. Bismuth triflate can be obtained using two methods: by reacting bismuth hydroxide with triflic acid, and by reacting bismuth oxide with triflic acid. The production of bismuth triflate from bismuth hydroxide is a long process that does not proceed to the end and has a yield of no more than 40%. The bismuth oxide obtained by thermal decomposition of bismuth hydroxide has several polymorphic modifications. Heating was carried out to 750 °C and cooled for 8 hours. The γ-bismuth oxide obtained in this way is dissolved in triflic acid for 2 hours and forms high-concentration solutions. The solubility values of bismuth triflate were determined at different acidity levels. X-ray analysis showed that bismuth nonahydrate triflate formed needle-like crystals. The α-phase of bismuth oxide obtained by decomposition of bismuth hydroxide at 450 °C did not dissolve completely in the acid. The process was carried out for 4 hours, and the yield was 92%. The resulting crystals of a bipyramidal shape were studied by differential thermal analysis, which showed that the crystals are pentahydrate of bismuth triflate, which loses crystallization water in the temperature range of 64-130 °C. Up to 320 °C, the substance is thermally stable. At a temperature of 327 °C, it melts with decomposition, which is accompanied by the formation of bismuth oxo-sulfates. According to X-ray diffraction data, the composition of the resulting phases is Bi28O32(SO4)10 and Bi34.7O100S16. Further heating to 380 °C leads to the decomposition of bismuth oxo-sulfates, resulting in the formation of the stable monoclinic modification of bismuth oxide, α-Bi2O3.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трифторметансульфонат висмута (III)</kwd><kwd>трифликовая кислота</kwd><kwd>α-фаза оксида висмута (III)</kwd><kwd>γ-фаза оксида висмута (III)</kwd><kwd>оксосульфат висмута</kwd><kwd>термический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>введите здесь ключевые слова на английском языке</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">Siddig L.A., Alzard R.H., Nguyen H.L. et al.
