Изобретение относитс  к способам получени  дихлорида и дибромида ванади , которые могут быть использованы дл  электролитического получени  металлического ванади  высокой чистоты.This invention relates to methods for producing vanadium dichloride and dibromide, which can be used to electrolytically produce high purity metal vanadium.

Известен способ получени  дихлорида и дибромида ванади  из соответствующих галогенидов ванади  более высокой валентности (из тетра- и трихлор ида ванади  и соответственно из тетра- и трибромида ванади ) путем их восстановлени  водородом пр.и нагревании до 450-580°С.A known method for producing vanadium dichloride and dibromide from corresponding vanadium halides of higher valence (from tetra- and trichloro-vanadium vanadium and from tetra- and vanadium tribromide, respectively) by reducing them with hydrogen and heating to 450-580 ° C.

Предлагаемый способ отличаетс  от известного тем, что в качестве восстановител  используют горючий природный газ. Это позвол ет интенсифицировать процесс. Врем  процесса составл ет 20-30 мин.The proposed method differs from the known one in that combustible natural gas is used as a reducing agent. This allows the process to be intensified. The process time is 20-30 minutes.

Пример 1. В контейнер загружают 120 г трихлорида ванади  и при температуре 450- 600°С подают природный горючий газ в количестве , на 20% превышающем стехиометрическое длЯ восстановлени  трихлорида ванади . Процесс ведут в течение 20-.30 мин. ВыходExample 1. 120 g of vanadium trichloride are loaded into a container and, at a temperature of 450–600 ° C, natural combustible gas is fed in an amount that is 20% higher than the stoichiometric for the reduction of vanadium trichloride. The process is carried out for 20-30 minutes. Output

по веществу составл ет 96-98%. При использовании полученного продукта дл  электроли тического получени  ванади  получен металлический ванадий чистотой 99,85%; выход поsubstance is 96-98%. When using the obtained product for the electrolytic production of vanadium, metallic vanadium with a purity of 99.85% was obtained; output by

току составл ет 85-95%.the current is 85-95%.

При м ер 2. В контейнер загружают 120 г трибромида ванади  и ведут процесс как в примере 1, но при температуре 450-550°С в течение 30 лгин. Выход по веществу составл ет 96-97%.At measure 2, 120 g of vanadium tribromide is loaded into a container and is carried out as in Example 1, but at a temperature of 450-550 ° C for 30 lg. The substance yield is 96-97%.

Аналогичные результаты получены при использовании в качестве исходных тетрахлорида и тетрабромида ванади .Similar results were obtained using vanadium as tetrachloride and tetrabromide as starting materials.
