EMI1.3
ausgewaschen und im Vakuum über Schwefelsaure getrocknet. Zum Unterschied vom nicht azetylierten Produkt ist es bereits in Soda leicht löslich, nicht löslich in verdünnten Sauren. Es löst sich leicht in Azeton, weniger in Alkohol, gar nicht in Ather, Kohlenwasserstoffen, Wasser. Es schmilzt um 2000.
EMI1.4
rührt noch kurze Zeit durch, saugt dann die ausgeschiedene Oxyphenylurethanarsinsäure ab, wäscht sie mit Wasser und trocknet. Die Reduktion kann wie in Beispiel 1 ausgeführt werden und liefert das Arsenooxyphenylurethan als ein hellgelbes, mikrokristallinisches Pulver, nicht löslich in wässerigen Säuren, leicht löslich in Alkalien und Natriumkarbonat.
Beispiel 3 : Eine Lösung von 116'5g Aminophenolarsinsäure in 750 cm3 Wasser und 250 cm3 zweifachnormaler Natronlauge wird nacheinander mit 120 g Kaliumcyanat und 12U cm3 Eisessig versetzt und 12 Stunden stehen gelassen. Aug der filtrierten Lösung kann die Oxyphenylharnstoffarsinsäure durch Salzsäure unsgefallt werden.
Die Reduktion liefert, in gleicher Weise wie oben ausgeführt, das s Dikarbannnodioxy- arsenobenzol, ein schwefelgelbes Pulver, leicht löslich in Soda, lÖslich in Azeton und Alkohol. nicht löslich in Ather, Wasser und wässerigen Säuren. Es zersetzt sich oberhalb 200 ohne scharfen Schmelzpunkt.

Process for the preparation of derivatives of aminoxyarylarsinic acids,

EMI1.3
washed out and dried in vacuo over sulfuric acid. In contrast to the non-acetylated product, it is already easily soluble in soda, not soluble in dilute acids. It dissolves easily in acetone, less in alcohol, not at all in ether, hydrocarbons, or water. It melts around 2000.
EMI1.4
stir for a short time, then sucks off the oxyphenyl urethanarsinic acid which has separated out, washes it with water and dries. The reduction can be carried out as in Example 1 and gives the arsenooxyphenyl urethane as a pale yellow, microcrystalline powder, not soluble in aqueous acids, easily soluble in alkalis and sodium carbonate.
Example 3: A solution of 116.5 g of aminophenolar acid in 750 cm3 of water and 250 cm3 of double normal sodium hydroxide solution is successively mixed with 120 g of potassium cyanate and 12U cm3 of glacial acetic acid and left to stand for 12 hours. In the filtered solution, the oxyphenylureaarsinic acid can be precipitated by hydrochloric acid.
The reduction gives, in the same way as described above, the s dikarbannodioxyarsenobenzene, a sulfur-yellow powder, easily soluble in soda, soluble in acetone and alcohol. insoluble in ether, water and aqueous acids. It decomposes above 200 without a sharp melting point.
