Description

Примен емые в насто щее врем  способы получени  реактивного бромата бари  основаны на взаимодействии бромата кали  с хлористым барием. Бромат кали  получают путем обработки едкой щелочи жид КИМ бромом; поэтому бромат кали  обходитс  очень дорого и операции по его получению требуют дорогих меропри тий по технике безопасности .The currently used methods for producing reactive barium bromate are based on the interaction of potassium bromate with barium chloride. Potassium bromate is produced by treating caustic alkali with a liquid KIM with bromine; therefore, potassium bromate is very expensive and operations to obtain it require expensive safety measures.

Предложенный новый способ получени  бромата кали  заключаетс  в том, что бромат кальци , получаемый бромированием 5-6% известкового молока промышленной бромовоздушной смесью (авт. св. № 9486 от 31 декабр  1948 г.) или другим известным путем, обрабатывают хлористым барием.The proposed new method for the production of potassium bromate is that calcium bromate obtained by brominating 5-6% of milk of lime with an industrial bromo-air mixture (ed. St. 9486 dated December 31, 1948) or by other known means is treated with barium chloride.

Указанные растворы, содержащие бромат и бромид кальци  в соотношении 1:5, отдел ют от шлама и упаривают до уд. веса 1,35-1,40. , Если раствор окрашен в розовый цвет, вызываемый образованием феррата кальци , то его обрабатывают аммиаком и отдел ют от выпавшего :осадка (СаСОз, гидроокиси кальци  и железа). Затем раствор осторожно нейтрализуют 10-15%-ной сол ной кислотой. Если при этом наблюдаетс  выделение небольших количеств свободного бари , то его нейтрализуют аммиаком.Said solutions containing bromate and calcium bromide in a ratio of 1: 5 are separated from the slurry and evaporated to be beats. weight 1.35-1.40. If the solution is colored pink, caused by the formation of calcium ferrate, it is treated with ammonia and separated from the precipitate: precipitate (CaCO3, calcium hydroxide and iron). Then the solution is carefully neutralized with 10–15% hydrochloric acid. If this results in the release of small amounts of free barium, it is neutralized with ammonia.

Прозрачный раствор нагревают до 50-60° и .. прибавл ют хлористый барий с избытком в 1-2% против стехиометрического количества и охлаждают.The clear solution is heated to 50-60 ° and barium chloride is added with an excess of 1-2% against the stoichiometric amount and cooled.

Выдел ющиес  кристаллы бромата бари  отдел ют от раствора н промывают холодной водой до отрицательной реакции на ионы хлора и брома. Промытые кристаллы высущивают при 100--105°.The precipitated barium bromate crystals are separated from solution and washed with cold water until a negative reaction to chlorine and bromine ions occurs. The washed crystals are dried at 100--105 °.
