Verfahren zur Herstellung von Gluconaten
Es ist bereits bekannt, gewisse, vom menschli- chen Organismus benötigte Metalle für therapeuti- sche Zwecke in'gut verträgliche, wasserlösliche Salze zu 2berführen Eisen- und Calciumpräparate werden so schon seit längerem in Form von Gluconaten hergestellt.
In neuerer Zeit gewinnt die Verabreichung von Spurenelementen, zu denen n Metalle wie Kupfer, Zizi, Mangan umd Kobalt gehören, immer mehr an Bedeutung. Es wunde nun auch hier die Uberführung in Gluconate versucht, was jedoch. auf Grund der Löslichkeitseigenschaften dieser Salze einerseits und der, hohen Anforderungen bezüglich der Reinheit und exakte n und gleichmässigen Dosierung andererseits gewisse Schwierigkeiten) verursachte.
Diese Schwierigkeiten) wenden gemäss vorliegender Erfindung überwunden durch ein Verfahren, das auf einsr dop- pelten Umsetzung zwischen Bariumgluconat und dem Sulfat des betreffenden Metaüs, dessen Gluconat man herstellen will, beruht, und dadurch gekennzeichnet ist, dass man das Sulfat des betreffenden Metalls in wässriger Lösun ! g mit einem geringen Überschuss an Bariumgluconat umsetzt, das ausfallende Bariumsul- fat abfiltriert und das gewünschte Gluconat durch Kristallisation isoliert.
Die Reaktion kans dunch folgende Gleichung veranschaulicht werden :
EMI1.1
in, der Me das Kation des Spurenelements und x des sen Wertigkeit bedeutet.
Die Ausgangsmaterialien des erfmdungsgemässen Verfahrens sind in hinreichenden Reinheit leicht zu gänglich ; durch diesen Umstand erhält man das Glu conat in einer von Fremdionen verhältnismässig freien Lösung, wodurch, auch bei einem gegebenen- falls erforderlichen strkeren Einengen der Lösung, die direkte Isolierung eines reinen Produktes ermög- licht wind. Durch Umkristallisieren kann anschliessend veine weitere Reinigung vorgenommen werden.
Man verwendet bei der Durchführung des erfin dungsgemäsaen Verfahrens einen geringen Uberschuss an Bartiumionen, um die restlose Entfernung des Sulfates zu gewährleisten. Es wurde gefunden, dass diese Bariumionen bei der Kristallisation des Me-Gluconats in Lösung bleiben und keine Störung verursachen.
Da das Bariumsulfat mikrokristallin anfällt, be- reitet seine Filtration Schwierigkeiten. Um diese zu umgehen, empfiehlt es sich, die Zugabe des Barium ghiconats zur Metallsulfatlösung in 2 Teilmengen vorzunehmen. Dabei werden durch die erste Portion Kristallkeime gebildet, die bei Zugabe der zweiten Portion zu relativ grossen Kristallen anwachsen,
Beispiel
Man löst etwa 0, 2 Mol des Metallsulfats in 300 ml dest. Wasser, Durch Zugabe von wenig ln-Salzsäure wird der pH-Wert der Lösung auf ca. 3 eingestellt. Man erwärmt auf etwa 90 und gibt die Hälfte einer 10%igen Lösung von 132 g (0, 25 Mol) Bariumgluconat in dest. Wasser zu.
Man lässt das Reaktionsgemisch mehrere Stunden auf dem Wasserbad stehen, setzt sodann die restliche Bariumgluco natlösung zu und hält das Gemisch zuerst noch 2 Stunden n bei 90 (Wasserbadtemperatur), dann 48 Stunden) bei 60 . Sodann wird abfiltriert. D. as da, s ge- wünschte Gluconat sowie überschüssiges Bariumgluconat enthaltende Filtnat wird im Vakuum eingeengt bis zur beginnenden Kristallisation. Dann wird unter Vakuum abgenutscht und der. Filterkuchen) 4 mal mit 1 /oiger Gluconsäurelösung und 1 mal mit dest. Wasser gewaschen. Nach dem Trocknen erhält man ein kristallines Produkt von für pharmazeutische Zwecke ausreichender Reinheit.
Falls eine weitere Reinigung erwünscht ist, kann man wie folgt vorgehen :
Man löst die erhaltenen Kristalle in ca. 100 ml , dest. Wasser. Die Häfte dieser Lösung wird in ca.
500 ml Äthanol (pharmazeut. Reinheitsgrad) eingegossen. Nach kräftigem Rühren lässt man 10 min stehen, rührt nochmals kräftig und lässt absitzen.
Falls di. Lösung nach 10 min noch trübe ist, wird nochmals gerührt. Sobald sich alles abgesetzt hat, wird über Büchnen-Filter filtriert. Mit ! dem Filtrat behandelt man den 2. Teil der konzentrierten Gluco naüösung auf dieselbe Weise. Man. trocknet das Glu conat im Vakuum und pulverisiert es.
Process for the production of gluconates
It is already known that certain metals required by the human organism for therapeutic purposes can be converted into well-tolerated, water-soluble salts. Iron and calcium preparations have been produced in this way in the form of gluconates for a long time.
In recent times, the administration of trace elements, including metals such as copper, zinc, manganese and cobalt, has become more and more important. There was now an attempt to convert it into gluconates, but it did so. caused certain difficulties due to the solubility properties of these salts on the one hand and the high requirements in terms of purity and exact and uniform dosing on the other.
According to the present invention, these difficulties are overcome by a process which is based on a double reaction between barium gluconate and the sulfate of the metal in question whose gluconate is to be produced, and is characterized in that the sulfate of the metal in question is aqueous Solution! g is reacted with a small excess of barium gluconate, the barium sulphate which has precipitated is filtered off and the desired gluconate is isolated by crystallization.
The reaction can be illustrated by the following equation:
EMI1.1
in, which Me means the cation of the trace element and x its valence.
The starting materials of the process according to the invention are readily available in sufficient purity; As a result of this, the gluconate is obtained in a solution that is relatively free of foreign ions, which enables a pure product to be isolated directly, even if the solution is concentrated more if necessary. Further purification can then be carried out by recrystallization.
When carrying out the process according to the invention, a small excess of bartium ions is used to ensure complete removal of the sulfate. It was found that these barium ions remain in solution during the crystallization of the Me-gluconate and do not cause any interference.
Since the barium sulfate is microcrystalline, its filtration causes difficulties. To avoid this, it is advisable to add the barium ghiconate to the metal sulfate solution in 2 partial amounts. The first portion forms crystal nuclei that grow into relatively large crystals when the second portion is added,
example
Dissolve about 0.2 mol of the metal sulfate in 300 ml of distilled water. Water, the pH of the solution is adjusted to approx. 3 by adding a little ln hydrochloric acid. It is heated to about 90 and half of a 10% solution of 132 g (0.25 mol) of barium gluconate in distilled water is added. Water too.
The reaction mixture is left to stand on the water bath for several hours, the remaining barium gluconate solution is then added and the mixture is first kept at 90 (water bath temperature) for 2 hours, then at 60 for 48 hours. It is then filtered off. The desired gluconate as well as the filtrate containing excess barium gluconate is concentrated in vacuo until crystallization begins. Then it is sucked off under vacuum and the. Filter cake) 4 times with 1 / o gluconic acid solution and 1 time with dist. Water washed. After drying, a crystalline product of sufficient purity for pharmaceutical purposes is obtained.
If further cleaning is required, you can proceed as follows:
The crystals obtained are dissolved in approx. 100 ml of distilled water. Water. Half of this solution is poured into approx.
500 ml of ethanol (pharmaceutical grade) poured in. After vigorous stirring, the mixture is left to stand for 10 minutes, vigorously stirred again and allowed to settle.
If di. If the solution is still cloudy after 10 min, the mixture is stirred again. As soon as everything has settled, it is filtered through a Büchnen filter. With ! The second part of the concentrated gluco solution of the filtrate is treated in the same way. Man. dries the gluconate in a vacuum and pulverizes it.
