PATENTAMT.PATENT OFFICE.

Es wurde gefunden, daß man feste, haltbare Präparate von Alkalisalzen des 4It has been found that solid, durable preparations of alkali salts of the 4th

3 · 31-diaminoarsenobenzols gewinnt, indem man Lösungen dieser Salze mit mehrwertigen Al· koholen, wie Mannit, Dulcit, Erythrit, Arabit usw., versetzt und sodann aus solcher Lösung durch Zugabe von indifferenten Mitteln, wie Alkohol und Äther, die neuen Präparate fällt und abtrennt. In denselben liegen nicht neue chemische Verbindungen, sondern innige Gemenge der genannten Alkalisalze mit den mehrwertigen Alkoholen vor. Die neuen Präparate sind zitronengelbe, in Wasser leicht und mit alkalischer Reaktion lösliche, in Alkohol und Äther schwer lösliche Pulver. Im Vergleich zu den reinen Alkalisalzen des Diaminodioxyarsenobenzols sind die neuen Präparate haltbar, namentlich dann, wenn sie unter Luftabschluß aufbewahrt werden.3 · 3 1 -diaminoarsenobenzene is obtained by adding polyhydric alcohols to solutions of these salts, such as mannitol, dulcitol, erythritol, arabitol, etc., and then from such a solution by adding inert agents such as alcohol and ether, the new preparations falls and separates. They do not contain new chemical compounds, but intimate mixtures of the alkali salts mentioned with the polyhydric alcohols. The new preparations are lemon-yellow powders that are easily soluble in water and with an alkaline reaction, and poorly soluble in alcohol and ether. Compared to the pure alkali salts of diaminodioxyarsenobenzene, the new preparations are stable, especially if they are kept in the absence of air.

Zur Darstellung der neuen Präparate verfährt man wie folgt:To display the new preparations, proceed as follows:

Beispiele.Examples.

i. 47,5 g 4 · 4^DiOXy-S · 31-diaminoarsenobenzolchlorhydrat werden in 200 ecm Wasser gelöst und mit der theoretischen Menge zehnfach normaler Natronlauge versetzt (= 40 ecm). Zu dieser Lösung fügt man 17,2 g Mannit, gelöst in 75 ecm Wasser.i. 47.5 g of 4 · 4 ^ DiOXy-S · 3 1 -diaminoarsenobenzene chlorohydrate are dissolved in 200 ecm of water and mixed with the theoretical amount of ten times normal sodium hydroxide solution (= 40 ecm). 17.2 g of mannitol, dissolved in 75 ecm of water, are added to this solution.

Mischt man die so hergestellte Lösung mit 4 1 absolutem Alkohol und 4 1 Äther, so fällt ein gelbes Pulver aus, das in Wasser leicht, in Alkohol, Äther, Aceton schwer löslich ist.If the solution prepared in this way is mixed with 4 liters of absolute alcohol and 4 liters of ether, it precipitates a yellow powder, which is easily soluble in water but sparingly soluble in alcohol, ether, acetone.

2- 47»5 S 4' 41OiOXy-S · 31-diaminoarsenobenzolchlorhydrat werden in 240 ecm Wasser gelöst, mit 40 ecm zehnfach normaler Na O H versetzt und zu der alkalischen Lösung 12,2 g Erythrit in 40 g Wasser zugegeben. Beim Einfließenlassen der Lösung in Alkohol oder Äther, oder Älkohol-Äthergemisch wird ein gelbes Pulver gefällt, welches sich leicht in Wasser, schwer in Alkohol, Äther, Benzol, Aceton usw. löst. 2-47 »5 S 4 '4-1 OiOXy S · 3 1 -diaminoarsenobenzolchlorhydrat be dissolved in 240 cc of water, mixed with 40 cc of ten times normal Na OH and 12.2 g of erythritol in 40 g of water was added to the alkaline solution. When the solution is poured into alcohol or ether, or a mixture of alcohol and ether, a yellow powder is precipitated which dissolves easily in water, difficult in alcohol, ether, benzene, acetone, etc.
