Изобретение относитс к области получени соединений фосфора, в частности монофторфосфата бари .The invention relates to the field of producing phosphorus compounds, in particular barium monofluorophosphate.
Известен способ получени монофторфосфата бари путем плавлени при температуре выше метафосфата бари и фторида бари , вз тых в эквимолекул рных количествах , и кристаллизации из расплава монофторфосфата бари .A known method for producing barium monofluorophosphate is by melting at temperatures above barium metaphosphate and barium fluoride, taken in equimolar amounts, and crystallization from barium monofluorophosphate melt.
При осуществлении известного способа происходит частичное разложение монофторфосфата бари с потерей фтора и образованием б-Ва2Р2О7. При этом в продукте содержитс всего 20% монофторфосфата бари .In the implementation of the known method, partial decomposition of barium monofluorophosphate occurs with loss of fluorine and the formation of b-Ba2P2O7. At the same time, only 20% barium monofluorophosphate is contained in the product.
Дл повышени выхода продукта предлагаетс вести процесс при 800-850°С.To increase the yield of the product, it is proposed to conduct the process at 800-850 ° C.
Проведение процесса при 800-850°С позвол ет осуществл ть его без плавлени компонентов , что приводит к увеличению содержани монофторфосфата бари в готовом продукте до 95%.Carrying out the process at 800-850 ° C allows it to be carried out without melting the components, which leads to an increase in the content of barium monofluorophosphate in the finished product to 95%.
Пример. Смешивают 88,4 г Ва(РОз)2 и 52 г Вар2 и помещают смесь в тигель из стеклоуглерода . Закрытый тигель став т в другой тигель из кварцевого стекла и далее - в электрическую печь, нагретую до 850°С. Кварцевый тигель плотно закрывают пришлифованной крышкой. По огнеупорной трубке, вмазанной в крышку, во внутреннюю полость кварцевого тигл подают предварительно осушенный азот или аргон. Через 45-60 мин тигель из печи вынимают и извлекают продукт. В готовом продукте содержитс 95% монофторфосфата бари .Example. 88.4 g of Ba (PO3) 2 and 52 g of Var2 are mixed and the mixture is placed in a glass carbon crucible. A closed crucible is placed in another quartz glass crucible and then in an electric furnace heated to 850 ° C. The quartz crucible is tightly closed with a polished lid. The pre-dried nitrogen or argon is fed into the internal cavity of the quartz crucible through a refractory tube, which is plastered into the lid. After 45-60 minutes, the crucible is removed from the furnace and the product is removed. The finished product contains 95% barium monofluorophosphate.
