Description
Verfahren zur Darstellung eines Gemisches von in Wasser löslichen Arsenverbindungen. Es wurde gefunden, dass man zu einem Gemisch von wasserlöslichen Arsenverbin dungen von vorzüglichen Eigenschaften ge langt, wenn man Epihydrinalkohol auf p -Arsenobenzol-di-(1-phenyl-2'3-,dimethyl-4- amino-5-pyrazolon) einwirken lässt. Das Präparat zeigt gelbe Farbe und ist in Was ser klar löslich.
Beispiel: 63,1 gr p-Arsenobenzol di-(1-phenyl-2'3- dimethyl-4-amino-5-pyrazolon) werden in 200 cm3 Methylakohol suspendiert und dann mit suspendiert und dann mit 35 gr Epihydrinalkohol versetzt. Die Base geht in Lösung, die Reaktion ist beendigt, sobald eine gezogene Probe in Wasser klar löslich bleibt. Gegebenenfalls kann die Re aktion durch Erwärmen auf 60 unterstützt werden. Das Reaktionsprodukt aus p-Arseno- benzol - di- (1-phenyl-2'3-dimethyl-4-amino-5- pyrazolon) und Epihydrinalkohol wird mit Äther und Alkohol ausgefällt. Das Präpa rat zeigt gelbe Farbe und ist in Wasser klar löslich.
Method for the preparation of a mixture of water-soluble arsenic compounds. It has been found that a mixture of water-soluble arsenic compounds of excellent properties is obtained if epihydrin alcohol is acted on p -arsenobenzene-di- (1-phenyl-2,3-, dimethyl-4-amino-5-pyrazolone) leaves. The preparation shows a yellow color and is clearly soluble in water.
Example: 63.1 g of p-arsenobenzene di- (1-phenyl-2'3-dimethyl-4-amino-5-pyrazolone) are suspended in 200 cm3 of methyl alcohol and then suspended and then mixed with 35 g of epihydric alcohol. The base goes into solution, the reaction is ended as soon as a sample taken remains clearly soluble in water. If necessary, the reaction can be supported by heating to 60. The reaction product of p-arsenobenzene-di- (1-phenyl-2'3-dimethyl-4-amino-5-pyrazolone) and epihydrin alcohol is precipitated with ether and alcohol. The preparation shows a yellow color and is clearly soluble in water.
