Description
Veefahren 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 4'4- Dimlonomethyla,mino -'B' 3 -@diamino - p -,arsena- benzol einwirken lässt. Die erhaltene Sub stanz ist gelb und in Wasser leicht löslich.
Beispiel: 39,2 gr 4'4-Dimonomethylamino-3'3-di- amino-p-arsenobenzol werden mit 17 gr Epi- hydrinalkohol in 50 cm' Methylalkohol ein getragen. Nach eingetretener Lösung der Base wird mit Alkohol und Äther ausgefällt; das Reaktionsprodukt aus 4'4-Dimonomethyl- aminn-3'3-diamino-p-,axsenobenzol und Epi- hydrinalkohol wird abgesaugt. Die erhaltene Substanz ist gelb und in Wasser leicht löslich.
Process 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 allowed to act on 4'4-dimlonomethyla, mino -'B '3 - @ diamino - p -, arsenabenzene. The substance obtained is yellow and easily soluble in water.
Example: 39.2 g of 4'4-dimonomethylamino-3'3-di-amino-p-arsenobenzene are introduced into 50 cm 'of methyl alcohol with 17 g of epidehydrinal alcohol. After the base has dissolved, it is precipitated with alcohol and ether; the reaction product of 4'4-dimonomethylamine-3'3-diamino-p-, axsenobenzene and epidehydrinal alcohol is filtered off with suction. The substance obtained is yellow and easily soluble in water.
