Description
Изобретение относитс к области получени полимерных материалов на основе фосфатов, которые вл ютс термостойкими химически инертными материалами.This invention relates to the field of the production of phosphate-based polymeric materials, which are heat-resistant chemically inert materials.
Известен способ получени полифосфатов, например гептафосфатов кобальта, никел , титана, меди и железа, путем взаимодействи расплавленного метафосфата натри с окислами соответствующих металлов при температуре 800°С с последующим медленным охлаждением до температуры 720°С и быстрым охлаждением расплава до комнатной температуры; далее расплав отмывают водой.A method of producing polyphosphates, for example cobalt, nickel, titanium, copper and iron heptaphosphates, is obtained by reacting molten sodium metaphosphate with oxides of the corresponding metals at 800 ° C, followed by slow cooling to 720 ° C and rapidly cooling the melt to room temperature; then the melt is washed with water.
Дл получени октафосфата натри -хрома предлагаетс в качестве окисла металла брать окись хрома с избытком около 4-5%, а охлаждение проводить до комнатной температуры в течение 2-3 мин.To obtain sodium octaphosphate chromium, it is proposed to take chromium oxide with an excess of about 4-5% as a metal oxide, and to cool to room temperature for 2-3 minutes.
Полученный плав тщательно измельчают и избыток метафосфата натри отмывают водой или раствором сол ной кислоты.The resulting melt is thoroughly crushed and the excess sodium metaphosphate is washed with water or hydrochloric acid solution.
Пример. 30 г МаРОз плав т в электропечи , поднимают температру до 800°С, выдерживают расплав при этой температуре в течение 1 час и добавл ют к расплаву небольшими порци ми при непрерывном перемешивании 1,5 г (4,8%) окиси хрома. Смесь выдерживают при температуре 800°С еще 2 час и охлаждают до комнатной температуры в течение 2-Example. 30 g of MAROS is melted in an electric furnace, the temperature is raised to 800 ° C, the melt is kept at this temperature for 1 hour and 1.5 g (4.8%) of chromium oxide are added to the melt in small portions with continuous stirring. The mixture is maintained at a temperature of 800 ° C for another 2 hours and cooled to room temperature within 2-
3 мин, вылива плав на металлическую или керамическую пластинку. Зате.м плав измельчают и обрабатывают водой до отсутстагт в промывной воде фосфат-иона. Полученный отмытый осадок октафосфата натри -хролга в количестве 4 г содержит (в %): Na13,123 min, pouring the melt on a metal or ceramic plate. After that, the melt is crushed and treated with water until the phosphate ion is present in the wash water. The obtained washed precipitate of sodium octaphosphate -holga in the amount of 4 g contains (in%): Na13,12

Температура плавлени полученного продукта 1820°С, он термоустойчнв на воздухе до температуры выше 1000°С. 3 Предмет изобретени Способ получени иолифосфатов натри и металла путем взаимодействи расплавленно- . го метафосфата натри с окислами соответ- 5 ствующих -металлов при температуре около 4 800°С с последующим охлаждением расплава и отмывкой продукта водой, отличающийс тем, что, с целью получени октафосфата натри -хрома , в качестве окисла металла берут окись хрома с избытком около 4-5%, а охлаждение расплава провод т до комнатной температуры в течение 2-3 мин.The sodium octaphosphate chromium passes into a soluble state only by fusion of a mixture with a mixture of CaCO3 + KNOs or KiSaO; and is also immediately destroyed by molten alkalis. The melting point of the obtained product is 1820 ° C, it is heat-resistant in air to a temperature above 1000 ° C. 3 Subject of the Invention A method for the preparation of sodium and metal ioliphosphates by molten-metal interaction. sodium metaphosphate with oxides of the corresponding α-metals at a temperature of about 4,800 ° C, followed by cooling the melt and washing the product with water, characterized in that, in order to obtain sodium octaphosphate chromium, chromium oxide with an excess of metal oxide 4-5%, and cooling of the melt is carried out to room temperature within 2-3 minutes.
