Description
Существующий способ получени бромноватокислого кали состоит в бромироваиии едкого кали жидким бромом.The existing method of producing potassium bromide is to bromide caustic potash with liquid bromine.
При бромировании щелочи бромом только 1/5 часть брома расходуетс на получение бромноватокислого кали ; кроме того, продукт содержит около 1,5-2% примесей. Очистка полученного продукта представл ет большие затруднени и сопровождаетс потер ми брома.When alkali is brominated with bromine, only 1/5 of the bromine is consumed to produce potassium bromic acid; In addition, the product contains about 1.5-2% impurities. Purification of the product obtained is very difficult and is accompanied by bromine loss.
Предметом насто щего изобретени вл етс способ получени бромноватокислого кали путем взаимодействи смеси бромисто , бромиоватокислого кальци с хлористым калием.The object of the present invention is a process for the production of potassium bromide by reacting a mixture of bromide, calcium bromic acid and potassium chloride.
Растворы, содержащие бромноватокислый ка;1ьций получают, обрабатыва известковое молоко, содержащее активной окиси кальци не выще 6 %, жидким бромом или бромовоздущной смесью.Solutions containing bromic acid; 1% are obtained by treating lime milk containing active calcium oxide with no more than 6% liquid bromine or a bromo-air mixture.
Полученные щелока отдел ют от щламма, упаривают до удельного веса 1,4-1,45, нейтрализуют свободную окись кальци сол ной кислотой и фильтруют.The resulting liquors are separated from the slurry, evaporated to a specific gravity of 1.4-1.45, the free calcium oxide is neutralized with hydrochloric acid and filtered.
Концеитрированный щелок нагревают до температуры 80-100° и раствор ют в нем хлористый калий в количестве 150% против рассчитанного по реакции: Са (ВгОз), 2КС1 - ЗКВгОд + CaClaConcentrated liquor is heated to a temperature of 80-100 ° and potassium chloride is dissolved in it in an amount of 150% against calculated by the reaction: Ca (CrO3), 2X1 - SCWr + CaCla
При охлаждении раствора выпадают кристаллы бромноватокислого кали , которые отдел ют от маточника известными способами.When the solution is cooled, crystals of potassium bromide precipitate out, which are separated from the mother liquor by known methods.
Преимуществом предлагаемого способа вл етс применение вместо жидкого брома бромовоздушной смеси и известкового молока, приготовленного из негашеной извести. Маточник после выделени бромата кали может быть использован д.л получени брома.The advantage of the proposed method is the use of a bromo-air mixture and lime milk, prepared from quick lime instead of liquid bromine. The mother liquor, after the isolation of potassium bromate, can be used to obtain bromine.
Предмет изобретени Subject invention
Способ получени бромноватокислого кали , отличающийс тем, что, с целью увеличени выхода и удешевлени продукта, на смесь бромисто-бромноватокислого кальци , полученную путем взаимодействи брома или бромовоздушной смеси с известковым молоком, действуют хлористым калием и выпавщий при о.хлаждении бромноватокислый калий отдел ют известным способом.A method of producing potassium bromide, characterized in that, in order to increase the yield and reduce the cost of the product, calcium bromic acid bromide mixture obtained by reacting bromine or bromo air with lime milk is treated with potassium chloride and the potassium bromic acid discharged during ohlamine potassium bromide is known in a way.
