Description
Изобретение касаетс получени трехокиси ванади и может быть использовано, например в металлургии ванади .The invention relates to the preparation of vanadium trioxide and can be used, for example, in vanadium metallurgy.
Известен способ получени трехокиси ванади восстановлением его высших окислов, например п тиокиси ванади , водородом при нагревании . Процесс ведут вначале при 600°С в течение 2 час и затем при 900-1000 С в течение 6 час. При этом получают продукт с содержанием 96% трехокиси ванади . Однако такой способ имеет высокую температуру процесса , а также взрывоопасен.A known method for producing vanadium trioxide by reducing its higher oxides, for example vanadium pentoxide, with hydrogen when heated. The process is conducted initially at 600 ° C for 2 hours and then at 900-1000 ° C for 6 hours. You get a product with a content of 96% vanadium trioxide. However, this method has a high process temperature, and is also explosive.
Цель изобретепи - снижение температуры нроцесса и повышение его безопасностп.The purpose of the invention is to reduce the temperature of the process and increase its safety.
Дл этого в качестве восстановител используют газообразный аммиак.For this, gaseous ammonia is used as a reducing agent.
По предлагаемому способу процесс ведут при 300-600°С предпочтительно при .According to the proposed method, the process is carried out at 300-600 ° C, preferably at.
При осуществлении способа достигаетс снижение темнературы процесса, уменьшаетс взрывоопасность процесса. При этом получают конечпый продукт с содержанием 98-99% трехокиси ванади .With the implementation of the method, a reduction in the temperature of the process is achieved, the explosion hazard of the process is reduced. You get a final product with a content of 98-99% vanadium trioxide.
При м е р. Порошкообразную п тиокись ванади загрул ают в трубчатую печь (электропечь ), вытесн ют из реакционного пространства печи воздух действием газообразного аммиака и затем нагревают до 450°С. После этого в течение 3 час пропускают газообразный аммиак при перемешивании реакционной массы . После печь охлаждают до температуры несколько ниже 100°С и выгружают продукт.An example. Vanadium powdered pentoxide is loaded into a tube furnace (electric furnace), air is forced out of the reaction space of the furnace with ammonia gas and then heated to 450 ° C. After that, for 3 hours pass gaseous ammonia with stirring the reaction mass. After the oven is cooled to a temperature slightly below 100 ° C, the product is discharged.
Степень восстановлени н тиокиси ванади до трехокиси ванади составл ет 98-99%.The degree of reduction of vanadium thioxide to vanadium trioxide is 98-99%.
