Description
Известны способы очистки хлорида рубиди от кали , основанные, главным образом, на многократной нерекристаллизации соединений рубиди или на хроматографическом разделении рубиди и кали .Known methods of purification of rubidium chloride from potassium, based mainly on repeated non-recrystallization of rubidium compounds or on the chromatographic separation of rubidium and potassium.
Предлагаемый снособ очистки хлорида рубиди от кали по сравнению с известными упрощает технологию очистки и позвол ет получить хлористый рубидий с содержанием не более 0,05% кали .The proposed removal of rubidium chloride from potassium in comparison with the known ones simplifies the purification technology and makes it possible to obtain rubidium chloride with a content of not more than 0.05% potassium.
Особенность способа состоит в том, что технический хлорид рубиди перевод т при температуре 70-80° в водном растворе в бромйодхлорид, который после охлаждени раствора до - 5° и фильтрации прокаливают при температуре 300-350°.A feature of the method is that rubidium technical chloride is converted at a temperature of 70-80 ° in an aqueous solution into bromide chloride, which, after cooling the solution to -5 ° and filtering, is calcined at a temperature of 300-350 °.
Способ осуществл ют следующим образом.The method is carried out as follows.
Технический хлорид рубиди раствор ют при нагревании до 70-80 в минимальном количестве дистиллированной воды, после чего в раствор добавл ют определенное количе ство тонкоистертого йода и приливают бром. Смесь перемешивают при 70-80°до растворени всего количества йода; раствор охлаждают до 5°, выпавший красно-оранжевый осадок бромйодхлорида рубиди отфильтровывают, промывают неболыиими порци ми охлаладенной дистиллированной воды и прокаливают при 300- 350° до полного побелени осадка, который вл етс чистым хлоридом рубиди . Дл получени более чистой соли провод т одну-две перекристаллизации бромйодхлорида рубиди из водного раствора и промытый осадок хлорида рубиди прокаливают при указанной температуре.Technical rubidium chloride is dissolved by heating to 70-80 in a minimal amount of distilled water, after which a certain amount of finely ground iodine is added to the solution and bromine is poured. The mixture is stirred at 70-80 ° until all iodine is dissolved; the solution is cooled to 5 °, the precipitated red-orange precipitate of rubidium bromoiodchloride is filtered off, washed with small portions of cooled distilled water and calcined at 300-350 ° until the precipitate whitewash, which is pure rubidium chloride, is completely whitened. To obtain a purer salt, one to two recrystallization of rubidium bromoiodchloride from an aqueous solution is carried out and the washed precipitate of rubidium chloride is calcined at the indicated temperature.
