Description
Известен способ получени двойной сернокислой соли аммони и. магни , заключающийс в том, что суспензи порошков фосфогииса и полуобожженного доломита или каустического магнезита в растворе сульфата аммони обрабатывают раствором аммиака и углекислым газом.A known method for producing ammonium and sulfuric acid double salts. magnesium, which consists in the fact that a suspension of phosphohysis powder and semi-calcined dolomite or caustic magnesite in a solution of ammonium sulfate is treated with an ammonia solution and carbon dioxide.
Предложенный способ отличаетс от известного тем, что в качестве реагента, содержащего аммнак и карбонат поп, примеп ют соль бикарбопата аммопи . Указанное отличие значительно упрощает процесс и повышает выход готового Продукта.The proposed method differs from the known one in that a bicarbopate ammopi salt is used as a reagent containing amnac and pop carbonate. This difference greatly simplifies the process and increases the yield of the finished Product.
При М ер. Порошок гипса или фосфогииса п каустического доломита или магнезита смешиваютс в реакторе-смесителе с 15-22о/оным раствором сульфата аммони , с расчетом Ж : : 4 в конце реакции, туда же добавл етс соль бикарбоната аммони в количестве , соответствующем суммарному уравнению реакции и вс смесь перемешиваетс в течение 2-3 ч. Температура поддерживаетс на уровне 50-70°С, давление атмосферное. После окончани реакции в смесителе раствор отдел етс от осадка путем фильтрации и двойна сернокисла соль выкристаллизовываетс из раствора путем его охлаждепи до 5-15°С. Маточный раствор возвращаетс в процесс.When M er. Gypsum powder or phosphogyis p-caustic dolomite or magnesite is mixed in a mixing reactor with a 15-22 o / t ammonium sulfate solution, with the calculation G: 4 at the end of the reaction, the amount of ammonium bicarbonate the mixture is stirred for 2-3 hours. The temperature is maintained at 50-70 ° C, the pressure is atmospheric. After the completion of the reaction in the mixer, the solution is separated from the precipitate by filtration and the double sulfate salt crystallizes out of the solution by cooling it to 5-15 ° C. The mother liquor is returned to the process.
