| Abstract: | A method of sodium sesquicarbonate (Na2CO3 · NaHCO3 · 2H2O) producing by polythermal crystallization from the saturated solution at 100°C which contains NaCl, Na2CO3 and NaHCO3 at the molar ratio Na2CO3 : NaHCO3 = 2 : 1 is developed. It is shown that the product of the crystallization represents large crystals of lamellar shape with the length up to 2 mm. Functional scheme of production of Na2CO3 · NaHCO3 · 2H2O based on recycling of mother liquor and mixing with washing water is developed. It allows increasing the product yield from 54.7 to 74.3%. |
