Description
В основном авт. св. № 116891 описан способ получени двуокиси молибдена, характеризующийс тем, что восстановление высших молибденовых солей до четырехвалентных производ т обработкой исходного раствора соли металлическим молибденовым порошком в присутствии серной кислоты или сульфата аммони в автоклаве под давлением 15-25 атм, температуре от 150 до 250° и концентрации водородных ионов рН в пределах 1,5-3,0.Basically auth. St. No. 116891 describes a method for producing molybdenum dioxide, characterized in that the reduction of higher molybdenum salts to tetravalent salts is carried out by treating the initial salt solution with a metallic molybdenum powder in the presence of sulfuric acid or ammonium sulfate in an autoclave under a pressure of 15-25 atm, temperature from 150 to 250 ° and the concentration of hydrogen ions pH in the range of 1.5-3.0.
Предлагаемый способ позвол ет применить способ по авт. св. № 116891 дл получени двуокиси вольфрама из растворов его 6-валентных солей.The proposed method allows to apply the method according to the author. St. No. 116891 for the production of tungsten dioxide from solutions of its 6-valent salts.
Образование двуокиси вольфрама происходит в тех же услови х что и двуокиси молибдена.The formation of tungsten dioxide occurs under the same conditions as molybdenum dioxide.
Предмет изобретени Subject invention
Применение способа по авт. св. № 116891 дл получени двуокиси .вольфрама.Application of the method according to ed. St. No. 116891 for the production of tungsten dioxide.
