Description
Verfahren zur Herstellung eines Zinkkomplegsalzes. Gegenstand vorliegender Erfindung ist ein Verfahren zur Herstellung eines Zinkkomplex salzes, dadurch gekennzeichnet, dass man Brenzkatechin - 3 . 5 - disulfosäure, eine Sauer stoffverbindung des Zinks, eine Calcium- und eine Natriumverbindung in solchen Mengen aufeinander einwirken lässt, dass eine neutrale Endreaktion entsteht.
Von der Sauerstoffverbindung des Zinks geht in jedem Falle nur das Zink, und zwar stets nach dem gleichen Reaktionstypus, in den Endstoff über. Das gleiche gilt für die angewendeten Calcium- bezw. Natriumver- bindungen, von denen nur die Elemente Calcium und Natrium im Endstoff auftreten.
Zweckmässig geht man so vor, dass man zunächst aus der Natriumverbindung und der Disulfosäure eine Lösung des Natriumsalzes der Sulfosäure herstellt und dann auf diese Zinkoxyd und Calciumhydroxyd einwirken lässt. Zinkoxyd und Calciumhydroxyd können auch in statu nascendi angewendet werden.
Vorteilhaft ist es auch, zunächst aus der Cal ciumverbindung, der Natriumverbindung und der Disulfosäure ein gemischtes Ca-Na-Salz der Brenzkatechin - 3 . 5 - disulfosäure herzu stellen und darauf Zinkoxyd einwirken zu lassen, was ebenfalls in statu nascendi ge schehen kann.
Das neue Produkt des Verfahrens soll zur Herstellung von Injektionslösungen, die gegen Infektionskrankheiten wirksam sind, Verwendung finden.
<I>Beispiel:</I> 40 gr calcium-brenzkatechin-3.5-disulfo- saures Calcium-Natrium, gewonnen nach dem Verfahren des D.R.P. Nr. 549207 durch Ein wirkung eines Natrium- und eines Calcium- salzes auf Brenzkatechin - 3 . 5 - disulfosäure, werden mit 125 cm' Wasser und 4 gr Zink oxyd gekocht, bis Lösung eingetreten ist, was nach kurzer Zeit der Fall ist. Man filtriert und fällt durch Einrühren in Methylalkohol die gebildete Verbindung aus.
Nach dem Ab trennen und Trocknen erhält man das zink- brenzkatechin - 3 . 5 - disulfosaure Calcium-Na- trium als ein weisses Pulver, das leicht mit neutraler Reaktion in Wasser löslich ist.
Process for the production of a zinc complex salt. The present invention relates to a process for the production of a zinc complex salt, characterized in that pyrocatechol-3. 5 - disulfonic acid, an oxygen compound of zinc, a calcium and a sodium compound interacts in such amounts that a neutral end reaction occurs.
From the oxygen compound of the zinc, only the zinc passes over into the end product, always according to the same type of reaction. The same applies to the calcium or calcium used. Sodium compounds, of which only the elements calcium and sodium appear in the end product.
It is expedient to proceed in such a way that a solution of the sodium salt of the sulfonic acid is first prepared from the sodium compound and the disulfonic acid and then zinc oxide and calcium hydroxide are allowed to act on this. Zinc oxide and calcium hydroxide can also be used in statu nascendi.
It is also advantageous to first create a mixed Ca-Na salt of catechol from the calcium compound, the sodium compound and the disulfonic acid. 5 - disulfonic acid and let zinc oxide act on it, which can also happen in statu nascendi ge.
The new product of the process is intended to be used for the production of injection solutions that are effective against infectious diseases.
<I> Example: </I> 40 gr calcium pyrocatechol-3.5-disulfo-acid calcium-sodium, obtained according to the method of the D.R.P. No. 549207 by the action of a sodium and a calcium salt on catechol - 3. 5 - disulfonic acid, are boiled with 125 cm 'of water and 4 grams of zinc oxide until solution has occurred, which is the case after a short time. It is filtered and the compound formed is precipitated by stirring into methyl alcohol.
After separating and drying you get the zinc catechol - 3. 5 - calcium-sodium disulphate as a white powder, which is easily soluble in water with a neutral reaction.
