Изобретение относитс к способам получени декаванадата натри , который может быть использован, например, в технологии ванади .The invention relates to methods for producing decavadate sodium, which can be used, for example, in vanadium technology.
Известен способ получени декаванадата натри , заключающийс в том, что в раствор метаванадата натри ввод т уксусную кислоту и затем кристаллизуют конечный продукт (упаривание).A known method for the preparation of decavadate sodium is that acetic acid is introduced into the sodium metavanadate solution and then the final product is crystallized (evaporation).
Недостаток этого способа - невысокие чистота и степень однородности конечного продукта .The disadvantage of this method is the low purity and degree of homogeneity of the final product.
Цель изобретени - устранение указанного недостатка.The purpose of the invention is to eliminate this drawback.
Это достигаетс благодар тому, что исходный раствор нагревают до 70-80°С, ввод т в него п тиокись ванади , раствор ют ее, отфильтровывают раствор и кристаллизуют из фильтрата конечный продукт.This is achieved due to the fact that the initial solution is heated to 70-80 ° C, vanadium pentoxide is introduced into it, dissolved, filtered, and the final product is crystallized from the filtrate.
Целесообразно брать п тиокись ванади в стехиометрически необходимом количестве.It is advisable to take vanadium pentoxide in the stoichiometrically necessary amount.
При осуществлении способа получают продукт высокой чистоты и однородности.In carrying out the method, a product of high purity and uniformity is obtained.
Пример. В 200 мл раствора метаванадата натри , содержащего 20,49 г NaVOs, раствор ют при нагревании (75°С) 10 г п тиокиси ванади квалификации О.С.Ч. Раствор фильтруют и оставл ют при комнатной температуре дл кристаллизации конечного продукта .Example. In 200 ml of sodium metavanadate solution containing 20.49 g of NaVOs, 10 g of O.CH. The solution is filtered and left at room temperature to crystallize the final product.
Получен однородный осадок состава ;Na6VioO2824H2O. Индивидуальность полученного соединени подтверждена оптическим, дериватографическим, химическим методами и методом ИКС.A homogeneous precipitate of the composition; Na6VioO2824H2O was obtained. The individuality of the obtained compound was confirmed by optical, derivatographic, chemical methods and the X-ray method.
