Description

Verfahren zur Herstellung von Bariumoxyd. Die Erfindung betrifft die Herstellung von Bariumoxyd durch Erhitzen von Bariumsulfid mit in Wasser suspendierter Magnesia, wobei sich neben Bariumoxyd und unlöslichem Magnesiumhydroxyd Schwefelwasserstoff nach. folgender Gleichung bildet: BaS+Vg0+a H20-Ba0+Mg(OH)2+H.S. Es ist bekannt, Bariumsulfid mit Magnesiumsalzen und Wasser zu erhitzen, wobei sich neben Magnesiumhydroxyd und Schwefelwasserstoff ein Bariumsalz bildet; indessen war es nicht bekannt, daß die gleiche Reaktion auch mit in Wasser suspendierter Magnesia eintritt, wobei an Stelle des Bariumsalzes Bariumoxyd bzw. Bariumhydroxyd entsteht. Die Gewinnung von Bariumoxyd auf dem bisher üblichen Wege ist mit ziemlich großen Schwierigkeiten und Kosten verbunden, weil die Ausbeute bei den jetzt gebräuchlichen Verfahren verhältnismäßig gering ist. Das vorliegende Verfahren gibt eine nahezu theoretische Ausbeute, wobei noch das gleichzeitige Entstehen von Schwefelwasserstoff und die Verarbeitung des Gases zu Schwefelsäure ganz erhebliche Vorteile bieten.Process for the production of barium oxide. The invention relates to Manufacture of barium oxide by heating barium sulfide with it suspended in water Magnesia, with barium oxide and insoluble magnesium hydroxide being hydrogen sulfide after. the following equation forms: BaS + Vg0 + a H20-Ba0 + Mg (OH) 2 + H.S. It is known, Heat barium sulfide with magnesium salts and water, taking apart magnesium hydroxide and hydrogen sulfide forms a barium salt; however, it was not known that the same reaction also occurs with magnesia suspended in water, with an Place of the barium salt barium oxide or barium hydroxide is formed. The extraction of Barium oxide by the usual route is with great difficulty and costs associated with it, because the yield with the processes now in use is proportionate is low. The present process gives a nearly theoretical yield, wherein nor the simultaneous formation of hydrogen sulfide and the processing of the Gas to sulfuric acid offer very considerable advantages.
