Description
Известно получение кремнефтори«тых солей щелочных и щелочно-земельных металлов из фторсадержащих газов фосфато-туковой промышленности путем многократной циркул ции поглотител , с целью повышени в,нем концентрации поглощенного вещества. Авторы насто щего изобретени предлагают получать кремнефторид магни из отход щих газов фосфатоMgCOs+ . H2SiF6+aq Концентраци раствора кремнефторида магни путем многократной циркул ции раствора может быть подведена до насыщени при температуре около 56° (температура отход щих газов суперф осфатного производства 65- 70°), затем, раствор отдел етс от образовавщегос в нем шламма и поступает на кристаллизацию MgSiF6.6H2O. H,SiFe4-MgCl2 + aq Из полученного раствора после упарки его выкристаллизовываетс MgSiPe. бНгО. Полученный кремнефторид магни может быть применен, как известно, дл флуотирован)и строительных материалов с целью придани им водонепроницаемости и большей атмосфероустойчивости . туковой промышленности путем промывки , газов водной суспензией углекислого магни или раствором хлори.стого магни . В резу.дьтате реакции между имеющейс в газах кремнефтористоводородной кислотой и углекислым магнием будет получатьс раствор кремнефторида магни по уравнению: gSiPe+COa-fHjO-f aq.. После кристаллизации маточный раствор отдел етс от выделившихс кристаллов и поступает дл дальнейшего поглощени фтора из газов, а кристаллы после фуговани вл ютс готовым продуктом. В случае хлористого магни реакци протекает по уравнению: MgSiF6 + 2HCl + aq. Предмет изобретени . Способ получени кремнефторида магни , отличающийс тем, что фторсодержащие газы, получаемые при кислотной переработке фосфоритов и ainaтита , обрабатывают водной суспензией углекислого магни или водным раствором хлористого магни .It is known to obtain silica-fluorine alkali and alkaline-earth metal salts from fluorine-holding gases of the phosphate-tuk industry through multiple circulation of the absorber, in order to increase the concentration of absorbed substance in it. The authors of the present invention propose to produce magnesium silicate fluoride from phosphato MgCOs + flue gases. H2SiF6 + aq The concentration of magnesium silicate solution by repeated circulation of the solution can be brought to saturation at a temperature of about 56 ° (the temperature of the waste gases of the superfate oxide production is 65-70 °), then the solution is separated from the slime formed in it and fed to crystallization MgSiF6.6H2O. H, SiFe4-MgCl2 + aq From the resulting solution, after evaporation of it, MgSiPe crystallizes out. bngo. The magnesium magnesium fluoride obtained can be used, as is well known, for fluotirovan) and building materials in order to make them waterproof and more weather-resistant. of the tobacco industry by washing with gases with an aqueous suspension of magnesium carbonate or with a solution of chlorine and solid magnesium. In the course of the reaction between the hydrofluoric acid and magnesium carbonate in the gases, a solution of magnesium silicofluoride will be obtained by the equation: gSiPe + COa-fHjO-f aq .. After crystallization, the mother liquor is separated from the separated crystals and is fed for further absorption of fluorine from the gases, and the fugging crystals are the finished product. In the case of magnesium chloride, the reaction proceeds as follows: MgSiF6 + 2HCl + aq. The subject matter of the invention. A method of producing magnesium silicate fluoride, characterized in that the fluorine-containing gases obtained from the acidic processing of phosphate rock and acid, are treated with an aqueous suspension of magnesium carbonate or with an aqueous solution of magnesium chloride.
