Изобретение относитс к способам получени нового соединени хрома: бихромата-молибдата аммони состава (NH4)2Cr2O7X X(NH4)2MoO4, который может быть использован , например, в качестве катализатора.The invention relates to methods for producing a new chromium compound: ammonium dichromate-ammonium molybdate of (NH4) 2Cr2O7X X (NH4) 2MoO4, which can be used, for example, as a catalyst.
Сущность способа состоит в том, что водный раствор хромата аммони привод т во взаимодействие с трехокисью молибдена или молибденовой кислотой при 30-50°С, предпочтительно при 45°С.The essence of the method is that an aqueous solution of ammonium chromate is reacted with molybdenum trioxide or molybdic acid at 30-50 ° C, preferably at 45 ° C.
Пример. В 300 мл воды внос т 152,00 г хромата аммони и 71,97 г трехокисн молибдена и при непрерывном перемешивании нагревают до 45°С (до полного растворени реагентов ). При этом окраска раствора переходит от желтой до оранжево-красной. Раствор оставл ют при комнатной температуре дл Example. 152.00 g of ammonium chromate and 71.97 g of molybdenum trioxide are introduced into 300 ml of water and heated to 45 ° C with continuous stirring (until complete dissolution of the reagents). In this case, the color of the solution goes from yellow to orange-red. The solution is left at room temperature for
