Description
Verfahren zur Darstellung von 4-(Ogyäthyl)-amino-3-methyl-l-ogybenzol. Gemäss dem Verfahren des Zusatzpatentes Nr. 139369 gewinnt man 4-(Oxväthyl)-amino- 3-methyl-l-oxybenzol durch Kondensation von 1 1AIol. 4-Amino-3-inethyl-l-oxybenzol mit 1 Mol. eines Halogenhydrins des Glykols.
Wie gefunden wurde, kann man die gleiche Verbindung erhalten, indem man 1 Mol. 4-Amino-3-methyl-l-oxybenzol mit<B>1</B> Mol. Äthylenoxyd umsetzt.
<I>Beispiel:</I> 123 Teile 4-Amiiio-3-methyl-l-oxybenzol werden mit 1000 Teilen Wasser und 49 Tei len konzentrierter Schwefelsäure versetzt, unter Rühren auf 60 C erhitzt. Bei dieser Temperatur leitet man Äthylenoxyd ein, so lange, bis sich die ersten Spuren des Disubstitutionsproduktes zeigen. Nach Auf kochen, Neutralisieren mit Natriumcarbonat und Filtrieren lässt man erkalten. Das Filtrat arbeitet man in der in der Patentschrift Nr. 139369 beschriebenen Weise auf.
Process for the preparation of 4- (ogyethyl) -amino-3-methyl-1-ogybenzene. According to the process of the additional patent no. 139369, 4- (oxyethyl) -amino-3-methyl-1-oxybenzene is obtained by condensation of 1 1AIol. 4-Amino-3-ynethyl-1-oxybenzene with 1 mol. Of a glycol halohydrin.
It has been found that the same compound can be obtained by reacting 1 mole of 4-amino-3-methyl-1-oxybenzene with 1 mole of ethylene oxide.
<I> Example: </I> 123 parts of 4-amino-3-methyl-1-oxybenzene are mixed with 1000 parts of water and 49 parts of concentrated sulfuric acid and heated to 60 ° C. with stirring. Ethylene oxide is introduced at this temperature until the first traces of the disubstitution product appear. After boiling, neutralizing with sodium carbonate and filtering, it is allowed to cool. The filtrate is worked up in the manner described in Patent No. 139369.
