Description
Verfahren zur Darstellung von 2-Chlor-4[di-(ogyäthyl)]amino-l-ogybenzol. Wie gefunden wurde, erhält man 2-Chlor- 4-[di(oxyäthyl)]-amino-l-oxybenzol, wenn man 1 Mol. 2-Chlor-4-amino-l-oxybenzol mit 21M1. eines Halogenhydrins des Glykols kondensiert.
Die neue Verbindung bildet farblose, bei 112 C schmelzende Kristalle. Sie ist leicht löslich in Alkalien, Säuren, siedendem Wasser, Alkohol, Äthor, Aceton, Äthylacetat, wenig löslich in kaltem Wasser, sehr wenig löslich in Benzol und Chloroform. Sie kann unter anderem als photographischer Entwickler Verwendung finden. <I>Beispiel:</I> 143 Teile 2-Chlor-4-amino-l-oxybenzol werden mit 2000 Teilen siedenden Wassers und 180 Teilen Caleiumcarbonat angeschlemmt und unter Rühren mit etwa 200 Teilen Äthylenchlorhydrin versetzt.
Man erhitzt zum Sieden und kocht am Rückflusskühler, bis der Geruch nach Äthylenchlorhydrin ver- schwunden ist. Nach Zugabe von 165 Teilen Natriumearbonat filtriert man nach noch maligem Aufkochen das gebildete Calcium- carbonat ab und schüttelt aus dem erkalte ten Filtrat das 2-Chlor-4-[di(oxyäthyl)]-amino- 1-oxybenzol mit Äthylacetat aus. Nach dem Abdunsten des Extraktionsmittels hinterbleibt ein dunkel gefärbtes, beim Erkalten erstar rendes O1.
Die Verbindung wird durch Um kristallisieren z. B. aus Wasser, Alkohol oder Äthylacetat gereinigt.
Process for the preparation of 2-chloro-4 [di- (ogyäthyl)] amino-1-ogybenzene. As has been found, 2-chloro-4- [di (oxyethyl)] -amino-1-oxybenzene is obtained if 1 mol. 2-chloro-4-amino-1-oxybenzene is mixed with 21M1. of a halohydrin of glycol condensed.
The new compound forms colorless crystals that melt at 112 ° C. It is easily soluble in alkalis, acids, boiling water, alcohol, ether, acetone, ethyl acetate, slightly soluble in cold water, very slightly soluble in benzene and chloroform. Among other things, it can be used as a photographic developer. <I> Example: </I> 143 parts of 2-chloro-4-amino-1-oxybenzene are suspended in 2000 parts of boiling water and 180 parts of calcium carbonate, and about 200 parts of ethylene chlorohydrin are added while stirring.
The mixture is heated to the boil and refluxed until the odor of ethylene chlorohydrin has disappeared. After adding 165 parts of sodium carbonate, the calcium carbonate formed is filtered off after boiling again and the 2-chloro-4- [di (oxyethyl)] amino-1-oxybenzene is shaken out of the cold filtrate with ethyl acetate. After the extraction agent has evaporated, what remains is a dark-colored O1 that solidifies on cooling.
The compound is crystallized by order z. B. purified from water, alcohol or ethyl acetate.
