Verfahren zum Austreiben der Schwefelsäure aus neutralem NatriumsulfatProcess for driving off sulfuric acid from neutral sodium sulfate
und aus Ammdniumsulfat.and from ammonium sulfate.
Patentiert im Deutschen Reiche vom 12. November 1918 ab. Längste Dauer: 15.Juni 1933.Patented in the German Empire on November 12, 1918. Longest duration: June 15, 1933.

Es hat sich gezeigt, daß das Verfahren des Patents 336560, die Schwefelsäure mit Salzsäure auszutreiben, sich auch auf neutrales Natriumsulfat anwenden läßt.It has been shown that the method of patent 336560, the sulfuric acid with hydrochloric acid to drive out, can also be applied to neutral sodium sulfate.
Es wird als Endergebnis in diesem Falle die Gewinnung der Schwefelsäure des Natriumsulfats unter Verbrauch einer äquivalenten Menge Salzsäure erzielt.The end result in this case is the recovery of the sulfuric acid from sodium sulphate achieved with consumption of an equivalent amount of hydrochloric acid.
Die technische Bedeutung gründet sich darauf, daß SalzsäureThe technical importance is based on the fact that hydrochloric acid

B. aus Chlor magnesium und dem Chlor der Alkalielektrolysc — Schwefelsäure dagegen überwiegend ausländischer Erzeinfuhr zu ihrer Gewinnung bedarf.can be obtained from domestic raw materials - e.g. B. from chlorine magnesium and the Chlorine of the alkali electrolysc - sulfuric acid, on the other hand, mainly foreign ore imports to obtain them.
Das erforderliche Natriumsulfat kann z. B. in an sich bekannter Weise aus der Umsetzung von Magnesiumsulfat mit Kochsalz gewonnen werden. Auch fällt es als Nebenprodukt z. B. bei der chlorürendcn Röstung der kupfer-I)/.\v. zinkhaltigen Schwefelkiesabhrände.The required sodium sulfate can, for. B. in a manner known per se from the implementation can be obtained from magnesium sulphate with table salt. It also falls as a by-product z. B. in the chlorine roasting of the copper-I) /. \ v. zinc-containing pebbles.
Zur Entbindung der Schwefelsäure aus dem neutralen Natriumsulfat verfährt man in derselben Weise wie im Hauptpatent für die Behandlung des Bisulfats angegeben. Man behandelt also das Natriumsulfat mit einem Überschuß von Chlorwasserstoff bei Gegenwart von Wasser; z. B. kann man gasförmige Salzsäure bis zur Sättigung in eine wäßrige Lösung" des Natriumsulfats einleiten oder das feste Salz mit wäßriger Salzsäure von hoher Konzentration behandeln. In jedem Falle scheidet sich Kochsalz aus und man erdem Überschuß an aufgewandter Salz- säure verunreinigt ist. To remove the sulfuric acid from the neutral sodium sulphate, the procedure is the same as that indicated in the main patent for the treatment of the bisulphate. The sodium sulphate is thus treated with an excess of hydrogen chloride in the presence of water; z. For example, gaseous hydrochloric acid can be introduced into an aqueous solution of sodium sulfate until it is saturated, or the solid salt can be treated with aqueous hydrochloric acid of high concentration.
Ebenso wie neutrales Natriumsulfat verhält sich gegenüber Salzsäure auch Ammoniumsulfat. Auch aus diesem läßt sicli die Schwefelsäure in derselben Weise gewinnen wie im Hauptpatent mit Bezug auf das Natriumsulfat und oben mit Bezug auf das neutrale Natriumsulfat angegeben. Die wirtschaftliche Bedeutung auch dieses Verfahrens beruht auf der Möglichkeit der Gewinnung von Schwefelsäure aus heimischen Rohstoffen. Ammonsulfat wird schon jetzt in großem Maßstäbe, z. B. durch Umsetzung von synthetisch hergestelltem Ammonkarbonat mitAmmonium sulphate behaves in the same way as neutral sodium sulphate towards hydrochloric acid. From this, too, the sulfuric acid can be obtained in the same way as in the main patent with reference to sodium sulfate and above with reference to the neutral one Sodium sulfate indicated. The economic importance of this process is based on the possibility of extraction of sulfuric acid from domestic raw materials. Ammonium sulfate is already being used in large quantities Standards, e.g. B. by reacting synthetically produced ammonium carbonate with

Procedure
Sulfuric acid can be obtained indirectly from gypsum. In addition to sulfuric acid, chlorammon is produced; In this form, too, ammonia is a valuable fertilizer; in many cases, chlorammon, especially since it is very pure, is also used as such.
