Wird rohe Soda oder rohe Potasche für sich oder, was dem entspricht, Soda- oder Potasche-Riickstand mit einer dem darin enthaltenen Schwefelcalcium äquivalenten Menge von Soda oder Potasche unter einem Dampfdruck von ca. 3 cm. mit der entsprechenden Menge Wasser gekocht, so erhält man Lösungen von Schwefelnatrium bezw. Schwefelkalium. Die Zersetzung erfolgt hierbei schneller und vollständiger, wenn auf ein Aequivalent Natron oder Kali in der Mischung mehr als ein Aequivalent Schwefelcalcium vorhanden ist.Will be raw soda or raw potash on its own or, whichever corresponds to that, soda or potash residue with an amount of soda or potash equivalent to the calcium sulphide contained therein under a vapor pressure of approx. 3 cm. boiled with the appropriate amount of water, solutions of Sulfur sodium resp. Potassium Sulfur. The decomposition takes place faster and more completely, if there is more than one equivalent for one equivalent of soda or potash in the mixture Calcium sulfur is present.
