Description
EMI0001.0001
Verfahren <SEP> zur <SEP> Darstellung <SEP> von <SEP> 2-Chlor-4-[di-(oxyäthyl)l-amino-l-oxybenzol. Gemäss dem Verfahren des Zusatzpaten tes Nr. <B>139989</B> gewinnt man 2-Chlor-4-[di- (oxyäthyl)l-amino-l-oxybenzol duroh Konden sation von<B>1</B> Mol. 2-Chlor-4-amino-l-oxyben- zol mit 2 3,lol. eines Halogenhydrins des Glykols.
Wie gefunden wurde, erhält man die Z,1 <B>1</B> CI eiche Verbindung, wenn man<B>1</B> Mol. 2-Chloi--4-amino-l-oxybeiizol mit 2 Mol. Äthylenoxyd umsetzt.
<I>Beispiel:</I> 143 Teile 2-Chlor-4-amino-l-oxybenzol werden mit<B>1000</B> Teilen Wasser angeschlemmt und unter Rühren auf zirka<B>70 0</B> C erhitzt. Bei dieser Temperatur wird so lange Äthy- lenoxyd eingeleitet, bis das 2-Chlor-4-amino- 1-oxybenzol vollständig in das 2-Chlor-4-[di- (oxyäthyl)]-amino-l-oxybenzol übergegangen ist. Ilierauf wird aufgekocht, von wenig Verunreinigungen abfiltriert und das Filtrat im Vakuum vom Wasser befreit.
Das hin terbleibende dunkelgefärbte<B>Öl</B> erstarrt beim Erkalten. Man reinigt durch Umkristallisieren aus Wasser Alkohol, Äthylacetat und Ähn lichem und erhält auf diese Weise farblose Kristalle vom Schmelzpunkt 112'<B>0.</B>

Method <SEP> for <SEP> representation <SEP> of <SEP> 2-chloro-4- [di- (oxyethyl) l-amino-l-oxybenzene. In accordance with the method of additional patent no. <B> 139989 </B>, 2-chloro-4- [di- (oxyethyl) l-amino-l-oxybenzene is obtained by condensation of <B> 1 </B> mol 2-chloro-4-amino-1-oxybenzene with 2 3, lol. a halohydrin of glycol.
As has been found, the Z, 1 <B> 1 </B> CI compound is obtained if <B> 1 </B> mol. 2-chloro-4-amino-1-oxybeiizole with 2 mol. Ethylene oxide converts.
<I> Example: </I> 143 parts of 2-chloro-4-amino-l-oxybenzene are suspended in a mixture with <B> 1000 </B> parts of water and brought to about <B> 70 ° C. with stirring heated. Ethylene oxide is passed in at this temperature until the 2-chloro-4-amino-1-oxybenzene has completely converted into the 2-chloro-4- [di (oxyethyl)] amino-1-oxybenzene. Ilierauf is boiled, small amounts of impurities are filtered off and the filtrate is freed from water in vacuo.
The dark-colored <B> oil </B> that remains solidifies when it cools. It is purified by recrystallization from water, alcohol, ethyl acetate and the like, and in this way colorless crystals with a melting point of 112 'are obtained
