Description
Verfahren zur Herstellung von öxymethylphosphinigsaurem Calcium Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von oxymethylphosphinigsaurem Calcium. Bei der Einwirkung von unterphosphoriger Säure auf Formaldehyd bereitet die lung eines reinen Endproduktes Schwierigkeiten, und dies ist wohl ein Grund, daß bisher ox methylphosphinige Säure bzw. deren Salze kannt sind.Process for the production of calcium oxymethylphosphinous the The invention relates to a process for the preparation of oxymethylphosphinous acid Calcium. Prepares from the action of hypophosphorous acid on formaldehyde the development of a pure end product difficulties, and this is probably one reason that so far ox methylphosphinous acid or its salts are known.
Es wurde nun gefunden, daß man das bisher nicht bekannte oxymethylphosphinigsaureCalcium dadurch erhält, daß man auf Formaldehyd bzw. dessen Polymerislationsprodukt unterphosphorige Säure in wäßriger Lösung, vorzugsweise unter Luftabschluß und bei Temperaturen zwischen 50 und 600 C, einwirken läßt und nach Neutralisieren mit einem Calciumsalz durch Eindampfen der wäßrigen Lösung das entstandene Salz abscheidet. It has now been found that the previously unknown oxymethylphosphinous calcium obtained by hypophosphorous on formaldehyde or its polymerization product Acid in aqueous solution, preferably in the absence of air and at temperatures between 50 and 600 C, and after neutralizing with a calcium salt through Evaporation of the aqueous solution separates the resulting salt.
Es ist aus der USA.-Patentschrift 2 370 903 bekannt, durch Umsetzung einer konzentrierten Lösung von unterphosphoriger Säure mit Aldehyden bei 50 bis 600 Verbindungen der Formel bzw. nach der Neutralisation der Säure mit Basen die entsprechenden Salze zu erhalten.It is known from US Pat. No. 2,370,903, by reacting a concentrated solution of hypophosphorous acid with aldehydes in 50 to 600 compounds of the formula or to obtain the corresponding salts after neutralization of the acid with bases.
Von diesem in der genannten Patentschrift beschriebenen Verfahren unterscheidet sich das erfindungsgemäße Verfahren zur Herstellung von oxymethylphosphinigsaurem Calcium in wesentlicher Weise. Es gelingt nämlich nicht, das Reaktionsprodukt zwischen unterphosphoriger Säure und Formaldehyd direkt abzuscheiden, es muß dies vielmehr in Form des Calciumsalzes geschehen, das zur weiteren Reinigung gelangt, da die freie oxymethylphosphinige Säure im Gegensatz zu den in der erwähnten amerikanischen Patentschrift beschriebenen Substanzen flüssig ist. Eine Destillation kommt nicht in Frage, weil sich die Substanz dabei zersetzt. Daß sich das Calciumsalz zur Reinigung eignet und als solches wertvolle therapeutische Eigenschaften aufweist, war nicht vorauszusehen. Das Präparat zeigt nämlich, wie durch zahlreiche klinische Untersuchungen erwiesen wurde, eine ausgesprochen günstige, nicht zu erwartende Wirkung bei Osteoporosen sowie bei Röhrenknochenbrüchen, wo infolge Erhöhung der Werte der alkalischen Phosphatase die knöcherne Konsolidierung in Zeiträumen erfolgt, die wesentlich kürzer sind, als man sie bei Fraktu ren erfahrungsgemäß erlebt. From this method described in the cited patent specification the process according to the invention for the preparation of oxymethylphosphinous acid differs Calcium in an essential way. It does not succeed namely, the reaction product between To deposit hypophosphorous acid and formaldehyde directly, it must do so happen in the form of the calcium salt, which is used for further purification, since the free oxymethylphosphinous acid in contrast to those mentioned in the American Patent specification described substances is liquid. There is no distillation in question because the substance decomposes in the process. That the calcium salt is used for purification suitable and as such has valuable therapeutic properties, was not to foresee. The preparation shows namely how through numerous clinical examinations has been proven to have an extremely beneficial, unexpected effect on osteoporosis as well as in long bone fractures, where as a result of an increase in the values of alkaline phosphatase the bony consolidation takes place in periods that are much shorter, than experience has shown in fractures.
Beispiel I 2,5 kg unterphosphorige Säure 800/oil werden mit o,g5 kg Trioxymethylen in einer Stickstoftatmosphäre unter Rühren vorsichtig auf 40 bis 450 C erwärmt. Die Temperatur steigt von selbst auf 55 bis 6o0-C und wird nach dem Abflauen der ersten Reaktion während mehrerer Stunden auf dieser Höhe gehalten. Das klare, farblose, sirupöse Reaktionsprodukt wird zur Beseitigung geringer Mengen überschüssigen Formaldehyds im Vakuum konzentriert, die erhaltene rohe Säure mit Wasser verdünnt und mit Calciumcarbonat bis zur neutralen Reaktion versetzt. Die mit Kohle filtrierte Lösung wird im Vakuum konzentriert, wobei sich oxymethylphosphinigsaures Calcium als weißes, kristallinisches Pulver abscheidet. Nach Umlösen aus Wasser erhält man es in reiner Form mit folgenden Analysendaten: Ca-Gehalt = I7,4°/o (Theorie) gefunden = I7,350/o; P-Gehalt = 26,g°/o (Theorie) gefunden = 26,7 0/o. Example I 2.5 kg hypophosphorous acid 800 / oil are mixed with o, g5 kg trioxymethylene in a nitrogen atmosphere with stirring carefully to 40 bis 450 C heated. The temperature rises by itself to 55 to 6o0-C and is after The first reaction was kept at this level for several hours. The clear, colorless, syrupy reaction product is used to remove small amounts Concentrated excess formaldehyde in vacuo, the crude acid obtained with Dilute water and add calcium carbonate to a neutral reaction. the The solution filtered with charcoal is concentrated in vacuo, with oxymethylphosphinous acid Calcium separates as a white, crystalline powder. After dissolving from water it is obtained in pure form with the following analytical data: Ca content = I7.4% (theory) found = 17.350 / o; P content = 26. g% (theory) found = 26.7 0 / o.
Das so erhaltene oxymethylphosphinigsaure Calcium ist ein weißes Kristallpulver von leicht bitterem Geschmack, das sich bei Zimmertemperatur in etwa 8 Teilen Wasser mit neutraler Reaktion löst. Beim Erhitzen zersetzt sich das oxymethylphosphinigsaure Calcium oberhalb 3000 C ohne zu schmelzen unter Entwicklung von Phosphorwasserstoff. The calcium oxymethylphosphinic acid obtained in this way is white Crystal powder with a slightly bitter taste, which is approximately at room temperature Dissolves 8 parts of water with a neutral reaction. The oxymethylphosphinic acid decomposes on heating Calcium above 3000 C without melting with evolution of hydrogen phosphide.
Beispiel 2 I,35 kg unterphosphorige Säure 980/zig werden mit I,6kg Formaldehydlösung 38 Volumprozent während mehrerer Stunden auf 55 bis 600 erhitzt und das Reaktionsprodukt wie im Beispiel 1 aufgearbeitet. Example 2 I, 35 kg hypophosphorous acid 980 / zig are combined with 1.6 kg Formaldehyde solution 38 percent by volume heated to 55 to 600 for several hours and the reaction product worked up as in Example 1.
