The review presents the scientific-technical results of the development of halogenating butyl rubber alternative technologies. The author considered the directions for the development of the technology of halobutyl rubber production through the butyl rubber solid phase halogenation, butyl rubber bromination using the oxidizing agents and electrophilic solvents, and the application of electrochemically produced halogen aqueous solutions as the halogenating agents. The paper shows the possibilities of increasing the process efficiency during the solid-phase halogenation of butyl rubber by eliminating the solvent treatment cycle from the process chain. The author mentioned the disadvantages peculiar for this butyl rubber halogenation technology associated with temperature increase when mixing a polymer with a halogenating agent: a considerable drop in the Mooney viscosity index and the isomerization of units with the exo-methylene group, which results in the accelerated rubber vulcanization and time decrease before the vulcanization starts (scorching).</p><p>The author discusses the application of oxidizing agents and electrophilic solvents for the bromination of butyl rubber that allows achieving almost complete conversion of bromine at the significant reduction of the process duration and ensuring high homogeneity of the reaction product structure. Special attention is paid to the process of butyl rubber bromination in a rotor-film reactor. However, the combination of halogen formation steps and the evolved halogen hydride utilization possible when using the electrochemical production of halogens in the form of their aqueous solutions is considered the most optimal.</p><p> </p></abstract><trans-abstract xml:lang="ru"><p>Целью обзора является рассмотрение возможностей совершенствования существующей технологии крупномасштабного производства галобутилкаучуков, повышения экономической эффективности и снижения экологических рисков при ее реализации в промышленном масштабе. В обзоре представлены научно-технические результаты разработки технологий галогенирования бутилкаучука, альтернативных существующей в промышленности. Рассмотрены направления развития технологии производства галобутилкаучуков путем проведения твердофазного галогенирования бутилкаучука, осуществления бромирования бутилкаучука в присутствии окисляющих агентов и электрофильных растворителей, применения в качестве галогенирующих агентов водных растворов галогенов, получаемых электрохимическим способом. Показаны возможности повышения эффективности процесса при проведении твердофазного галогенирования бутилкаучука за счет исключения из технологической цепочки цикла обращения с растворителем. Отмечены недостатки, присущие данной технологии галогенирования, связанные с повышением температуры при смешении полимера с галогенирующим агентом: значительное падение показателя «вязкость по Муни» и изомеризация звеньев с экзометиленовой группой, следствием которой является ускорение вулканизации каучука и снижение времени до начала вулканизации (скорчинг). Обсуждается применение окисляющих агентов и электрофильных растворителей при проведении бромирования бутилкаучука, что позволяет достигнуть практически полной конверсии брома при значительном сокращении продолжительности процесса и обеспечить высокую однородность структуры продукта реакции. Особое внимание уделено осуществлению процесса бромирования бутилкаучука в роторно-пленочном реакторе. Однако наиболее оптимальным признано совмещение стадий образования галогена и утилизации выделяющегося галогеноводорода, возможное при использовании электрохимического получения галогенов в виде их водных растворов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>halobutyl rubber</kwd><kwd>butyl rubber halogenation</kwd><kwd>oxidative bromination</kwd><kwd>electrochemical preparation of halogen</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>галобутилкаучук</kwd><kwd>галогенирование бутилкаучука</kwd><kwd>окислительное бромирование</kwd><kwd>электрохимическое получение галогена</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Shcherban G.T., Lemaev N.V., Shiyapov R.T., Sofronova O.V., Ishteryakov A.D., Shamsutdinov V.G.
