Description
(54) СПОСОБ ПОЛУЧЕНИЯ СУЛЬФАТА ЩЕЛОЧНОГО МЕТАЛЛА(54) METHOD FOR PRODUCING ALKALINE METAL SULPHATE
950± 15° C, вдува воздух в алундовый конвер тер емкостью 300 смл.950 ± 15 ° C, blowing air into an alundum converter with a capacity of 300 cm.
Образовавшийс продукт в расплавленном состо нии сливают в кристаллизатор и охлаждают до комнатной температуры.The product formed in the molten state is drained into the crystallizer and cooled to room temperature.
Получено 17,2 г продукта с содержанием сульфата натри 98,, хлорида натри 0,4% нерастворимого в воде остатка 0,6%. Кальций, железо, роданид и тиосульфат не обнаружены. Валовый выход продукта от сухой (без учета влаги) смеси солей 91,5%. Выход сульфата натри , образовавшегос в результате конверсии тиосульфата и роданида, составил 88%, что близко к теоретическому значению.17.2 g of product were obtained with a sodium sulfate content of 98, sodium chloride 0.4% water-insoluble residue 0.6%. Calcium, iron, rhodanide and thiosulfate were not detected. The gross yield of the product from the dry (excluding moisture) salt mixture is 91.5%. The yield of sodium sulfate, formed as a result of the conversion of thiosulfate and rhodium, was 88%, which is close to the theoretical value.
Пример 2. Готов т смесь из 15 г роданида кали (ГОСТ 4139-65) и 15 г .т«осульфата кали (МРТУ 6-09- 1204-64). Указанную смесь ввод т на расплав сульфата кали и обрабатывают воздухом при 1080-1100° С в течение 1 час. Затем сливают расплавленный продукт и охлаждают его до комнатной температуры . Получено 2б,7 г. сульфата -кали с содержанием основного вещества 99,б/(к Вывлажной загрузки составилExample 2. A mixture of 15 g of potassium rhodanide (GOST 4139-65) and 15 g. Of potassium osulfate (MPTU 6-09-1204-64) is prepared. This mixture is introduced to the potassium sulphate melt and treated with air at 1080-1100 ° C for 1 hour. The melted product is then poured and cooled to room temperature. Received 2b, 7 g of sulphate -cali with the content of the main substance 99, b /
