Werden Borsäure und Kalk enthaltende Borate durch Zusatz von Borsäure in vierfach borsaures Calcium verwandelt oder mit so viel Schwefelsäure oder auch Bisulfat versetzt, dafs aus der freigemachten Borsäure und dem unzersetzten Borkalk vierfach borsaures Calcium entsteht, so setzt sich letzteres beim Kochen mit Glaubersalz nach der Formel:Become borates containing boric acid and lime by adding boric acid in fourfold calcium borate is transformed or mixed with so much sulfuric acid or bisulphate that it is possible from the liberated boric acid and the undecomposed boron lime, fourfold boric acid calcium arises, the latter settles when cooking with Glauber's salt according to the formula:
CaO(B2O3), + Na2SO4
= Na2 O (B2OJ,+ CaSO,
in vierfach borsaures Natrium und Gyps um. CaO (B 2 O 3 ), + Na 2 SO 4 = Na 2 O (B 2 OJ, + CaSO,
into quadruple sodium borate and gypsum.
Diese Reaction läfst sich zur Darstellung von Natriumboraten, namentlich Borax, vortheilhaft verwenden, wie folgendes Beispiel erläutern mag:This reaction can be used advantageously for the preparation of sodium borates, namely borax use, as the following example might explain:
100 Theile eines Borkalks von 45 pCt. Borsäure (B2 O3) und 31 pCt. Kalk (CaO), 200 Theile Wasser werden entweder mit 37 Theilen Schwefelsäure (100 pCt. H2 5O4), ca. 140 Theilen Glaubersalz (Na2 SOJ oder auch mit 91 Theilen Bisulfat (NaHSOJ, ca. 85 Theilen Glaubersalz (Na2 SO4) im Autoclaven bei 2Y2 Atmosphären Druck oder im offenen Kessel mit Rührer bis zur vollendeten Reaction gekocht und der ausgeschiedene Gyps durch eine Filtrirvorrichtung von der resultirenden Lauge getrennt..100 parts of a boron lime of 45 pCt. Boric acid (B 2 O 3 ) and 31 pCt. Lime (CaO), 200 parts of water are mixed with either 37 parts of sulfuric acid (100 pCt. H 2 50 4 ), about 140 parts of Glauber's salt (Na 2 SOJ or 91 parts of bisulfate (NaHSOI, about 85 parts of Glauber's salt (Na 2 SO 4 ) boiled in an autoclave at 2Y 2 atmospheres pressure or in an open vessel with a stirrer until the reaction is complete and the precipitated gypsum is separated from the resulting liquor by a filter device.
Letztere, welche die Borsäure als Natriumtetraborat enthält, wird durch eine beliebige Base, je nach der späteren Verwendung Soda oder Kalk oder Natriummonoborat, zur Abscheidung von Natriumbiborat (-Borax) neutralisirt. The latter, which contains the boric acid as sodium tetraborate, is replaced by any Base, depending on the later use, soda or lime or sodium monoborate, for separation neutralized by sodium borate (Borax).
