Изобретение относитс к способам получени нового соединени ванади : Двойного метаванадата кали и кальци состава КСа (УОз)з5Н2О. Это соединение может быть иснользовано в качестве реактива, а способ его получени - дл выделени ванади из растворов и отделени метаванадата кали от натри .The invention relates to methods for producing a new vanadium compound: Double potassium metavanadate and calcium of composition KSa (CP) 3 H 2 O. This compound can be used as a reagent, and its preparation method can be used to separate vanadium from solutions and separate potassium metavanadate from sodium.
Сундность способа состоит в том, что к раствору метаванадата кали добавл ют растворимую соль кальци , например его хлорид в 1 - 1,4-кратном количестве от стехиометрии, с последующим выдерживанием реакционной смеси в течение 12-24 час и отделением образующегос при этом осадка от раствора.The ability of the process is that a soluble calcium salt is added to a solution of potassium metavanadate, for example its chloride in 1 - 1.4 times the amount of stoichiometry, followed by keeping the reaction mixture for 12-24 hours and separating the precipitate formed from solution.
Дл интенсификации процесса и повыщени выхода конечного продукта целесообразно вести процесс при исходной концентрации метаванадата кали в растворе не менее 3,2 масс.%.In order to intensify the process and increase the yield of the final product, it is advisable to conduct the process with an initial concentration of potassium metavanadate in the solution of at least 3.2 mass%.
Пример. К 10 мл раствора метаванадата кали , содержащего 0,4918 г VaOs, добавл ют 0,297 г безводного хлористого кальци и выдерживают смесь при комнатной температуре в течение 12 час. Затем осадок отфильтровывают , дважды промывают водой при Т : Ж 1:1 и сущат на воздухе. Выход продукта (кристаллы светлого лимонно-желтого цвета ) 100% (по VaOs); состав отвечает формуле КСа(УОз)з бНоО; продукт содержит, масс, %: УОз -63,7; К- 8,35; Са -8,57; НаО-19,3.Example. 0.297 g of anhydrous calcium chloride is added to 10 ml of potassium metavanadate solution containing 0.4918 g of VaOs, and the mixture is kept at room temperature for 12 hours. Then the precipitate is filtered off, washed twice with water at T: W 1: 1 and grown in air. The product yield (crystals of light lemon yellow color) 100% (VaOs); the composition corresponds to the formula KSa (UOZ) s bNoO; The product contains, in mass,%: DL -63.7; K - 8.35; Ca -8.57; NaO-19.3.
