Использовано два метода синтеза: метод растворения твердой фазы, содержащей большое количество хлоридов, и метод выпаривания воды из суспензии. Выпаривание проводили при температуре 80 °С под вакуумом, а затем охлаждали. Определены химические составы жидких и твердых фаз. Установлено, что увеличение степени выпаривания (или уменьшение количества воды в системе) способствует замедлению роста выхода шенита и увеличению количества примесей в нем. При увеличении содержания хлорида магния в исходной суспензии степень выпаривания при синтезе шенита необходимо снижать. Полученные составы продуктов позволяют рассчитать степень выпарки шенитовой суспензии. </p></abstract><trans-abstract xml:lang="en"><p>Shoenite synthesis process from the suspensions with low sodium chloride content was investigated. Two techniques of synthesis were used: dissolution of solid phase which contains huge amount of chlorides and water evaporation from the suspension. The evaporation was carried out under vacuum at the temperature of 80 °C with subsequent cooling. Chemical compositions of solid and liquid phases were estimated. It was established that evaporation degree increase (or decreasе of the amount of water in the system) slows down the shoenite output and increases the impurities amount in it. Should the content of magnesium chloride in the initial suspension be increased, the evaporation degree during the shoenite synthesis should be decreased. The compositions of the products obtained allow us to calculate the evaporation degree of the shoenite suspension. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>шенит</kwd><kwd>степень выпаривания</kwd><kwd>щелок</kwd><kwd>суспензия</kwd><kwd>хлорид магния</kwd></kwd-group><kwd-group xml:lang="en"><kwd>shoenite</kwd><kwd>evaporation degree</kwd><kwd>lye</kwd><kwd>suspension</kwd><kwd>magnesium chloride</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">Печковский, В.
