PLThe longest term of the patent until August 24, 1944 According to patent No. 10948, solid potassium carbonate is obtained from potassium chloride for the processing of syllinite salts, while at the same time, by transforming carbamate, potassium and sodium, ammonium or carbonic anhydride are obtained In accordance with the present method, one grinds an aqueous or a little water containing a liquid-finely crude salt and mixes it with a fine ammonia. Potassium carbonate converts not, according to the method described in the patent by adding water and heating to heat No. 10948, with ammonium carbamate potassium bicarbonate, and then, according to (NH4CO2NHJ or with carbon anhydride known methods, into potassium carbonate in anhydrous or low water content The invention relates to the use of liquid ammonium chloride and sodium chloride to form solid carbamates (KCO2NH2 or NaGO2NH2) and the chlorine to bind to ammonium chloride soluble in liquid ammonium. The sediment separates from the solution and the mud is washed with ammonia. The mother liquor is treated as described in Patent No. 10948, and the resulting liquid ammonia is returned to the fabrication cycle. The sludge contains, in addition to potassium and sodium carbamate, all other constituents contained in the crude salt, insoluble in the liquid. With ammonia, they are treated without water, but the caribamates are converted to bicarbonate and can be separated from each other and from the rest of the ingredients by known methods. PL
