Description
Verfahren zur Herstellung von Bariumnitrat Es ist bekannt, daß man Bariumnitrat technisch aus Bariumchloridlösunge n und Salpeter herstellen kann. Die Umsetzung geht vorteilhaft nur in der Wärme vo.r sich, und das anfallende Bariumnitrat bedarf einer Umkristallisation. Wirtschaftlicher ist die Herstellung von Bariumnitrat aus Bariuntalilori-d und Salpetersäure, da hierbei als Nebenprodukt Salzsäure entsteht und das Alkali des Salpeters gespart wird.Process for the preparation of barium nitrate It is known that one Barium nitrate can be produced technically from barium chloride solutions and saltpeter. The conversion takes place advantageously only in the heat, and the barium nitrate produced requires recrystallization. The production of barium nitrate is more economical from Bariuntalilori-d and nitric acid, since hydrochloric acid is formed as a by-product and the alkali of nitric is saved.
Es ist nun gefunden worden, daß man d:ie Umsetzung von Bariumchlorid mit Salpetersäure, welcher normalerweise mit nur etwa 7o°)" Nutschenausbeute arbeitet, bedeutend günstiger bestalten kann, wenn man von einer Bariuanchlori@dl@au#g,e ausgeht, welche festes Chlorbarium zweckmäßig in feinkristallinisch,-r Form als Bodenkörper .enthält. Es ist überraschernd, @daß sich die Umsetzung der Salpetersäure mit -dem Bodenkörper leicht, ohne Wärmezufuhr und nahezu quantitativ vollzieht. Das anfallende Bariumnitrat ist blütenweiß und leicht durch Waschen von .der anhaftenden Satzsä.ure zu befreien. Man erhält auf diese Weise direkt 9o bis 95°1o der Theorie an chlorfreiem: Bariumnitrat als festes, trockenes ,Salz auf der Nutsche und als Filtrat eine 16- bis r 7 %ige Salzsäure, welche wieder zur Herstellung von Chlorbarium verwendet werden kann. Beispiel In 3z0 1 Lauge, enthaltend z25 kg BaC12. 2 H20, werden 155 kg festes Chlorbarium zweckmäßig in feinkristallinischer Form eingetragen und unter Rühren zog kg 69o'oige Salpetersäure nach und nach zugesetzt. Das ausgeschiedene Bariumnitrat wird abgenutscht und chlorfrei gewaschen. Die Ausbeute an chlorfreiem, verkaufsfähigem Produkt beträgt 275 kg, das sind 93 0!o der Theorie. Das Filtrat dient zur Herstellung von Chlorbarium.It has now been found that the reaction of barium chloride with nitric acid, which normally works with only about 70 °) suction filter yield, can be carried out significantly more cheaply if one starts out from a barium chloride contains solid chlorobarium appropriately in finely crystalline form as soil body. It is surprising that the reaction of nitric acid with the soil body takes place easily, without the supply of heat and almost quantitatively. The resulting barium nitrate is pure white and easily by washing In this way, 9o to 95 ° 1o of theory of chlorine-free: barium nitrate as a solid, dry salt on the suction filter and a 16 to 7% hydrochloric acid as a filtrate, which can be used again for production EXAMPLE 155 kg of solid chlorobarium are expediently introduced in finely crystalline form into 3.10 1 lye containing 25 kg BaC12.2 H 2 O and with stirring en drew kg 69o'oige nitric acid gradually added. The excreted barium nitrate is filtered off with suction and washed free of chlorine. The yield of chlorine-free, salable product is 275 kg, which is 93% of theory. The filtrate is used to produce chlorine barium.
