PATENTAMT.PATENT OFFICE.
Das den Gegenstand der vorliegenden Erfindung bildende Verfahren besteht darin, daß wasserlösliche oder unlösliche Bleisalze bei Gegenwart von Wasser mit passenden Mengen von Magnesiumoxyd und Carbonat, am zweckmäßigsten unter Rühren und bei Erwärmen auf. dem Wasserbade oder durch Einleiten von Wasserdampf behandelt werden, wobei die Bleisalze glatt in basisches Bleicarbonat übergeführt werden.The method forming the subject of the present invention consists in that water soluble or insoluble lead salts in the presence of water in appropriate amounts of magnesium oxide and carbonate, most expediently with stirring and with heating. the water bath or by introducing Steam treated, with the lead salts converted smoothly into basic lead carbonate will.
Von den Verfahren der deutschen Patentschriften 52562 und 74534 unterscheidet sich das vorliegende dadurch, daß, während nach jenen Verfahren Natrium- bezw. Kalihydroxyd und Carbonat zur Umwandlung der Bleisalze •in basisches Carbonat verwendet werden, nach dem vorliegenden Verfahren die in Wasser unlöslichen Magnesiaverbindungen, und zwar Magnesiumoxyd und Magnesiumcarbonat angewendet werden, welche Verbindungen, da dieselben nicht wie Alkalihydrat und Carbonat ätzende Wirkungen besitzen, die Verwendung von teueren emaillierten Eisenkesseln unnötig machen, so daß das Verfahren in Gefäßen aus beliebigem Material ausgeführt werden kann.From the method of German patents 52562 and 74534 differs the present in that, while according to those methods, sodium or. Potash Hydroxide and carbonate are used to convert the lead salts • into basic carbonate, according to the present process, the water-insoluble magnesia compounds, namely Magnesium oxide and magnesium carbonate are used, which compounds because the same as alkali hydrate and carbonate do not have corrosive effects, the use of expensive enameled iron kettles unnecessary, so that the process in vessels can be made of any material.
66,08 kg von Bleinitrat z. B. werden in 100 kg Wasser gelöst, zu der auf Wasserbadtemperatur erwärmten Lösung ein aus 4 kg Magnesiumoxyd und 8,4 kg Magnesiumcarbonat bestehendes Gemisch gegeben und das Ganze unter Erhitzen und ständigem Umrühren etwa 5 Stunden lang digeriert. Das gebildete Bleicarbonat wird abkoliert und ausgewaschen. Die Ausbeute ist theoretisch.66.08 kg of lead nitrate e.g. B. are dissolved in 100 kg of water at the water bath temperature heated solution given a mixture consisting of 4 kg of magnesium oxide and 8.4 kg of magnesium carbonate and the whole thing Digested with heating and constant stirring for about 5 hours. The lead carbonate formed is stripped off and washed out. The yield is theoretical.
55,48 kg Bleisulfat, 50 kg Wasser, 4 kg Magnesiumoxyd und 8,4 kg Magnesiumcarbonat werden unter Umrühren gut gemischt und in dieses Gemisch unter Fortsetzung des Umrührens Wasserdampf eingeleitet. Nach etwa ι ο stündigem Digerieren wird koliert und ausgewaschen. Ausbeute fast theoretisch.55.48 kg lead sulfate, 50 kg water, 4 kg Magnesium oxide and 8.4 kg of magnesium carbonate are mixed well with stirring and added to this mixture while continuing Stirring steam initiated. After about ι o hours of digestion, it is colourized and washed out. Almost theoretical yield.
Die in dem letzteren Beispiele angeführten Zahlen entsprechen der Umsetzungsgleichung, welche sich wie folgt darstellt:The numbers given in the latter example correspond to the conversion equation, which is as follows:
2 Pb SO4 + Mg O + Mg CO3 + H2O =2 Pb SO 4 + Mg O + Mg CO 3 + H 2 O =
Pb (OHJ2 -PbCO3 + 2 Mg SO*.Pb (OHJ 2 -PbCO 3 + 2 Mg SO *.
Selbstverständlich können statt der im Beispiel genannten auch andere Bleisalze verwendet werden, ebenso die. Verhältniszahlen variieren.Of course, other lead salts can also be used instead of those mentioned in the example as well as the. Ratios vary.
