    Verfahren <SEP> zur <SEP> Darstellung <SEP> von <SEP> 1-Rethyl-4-methoxy-3-(@. <SEP> y-dioxypropyl  oxyäthyla,mino)-benzol.       Gemäss dem im Hauptpatent beschriebenen  Verfahren erhält man     N-Oxyäthyl-N-ss    .     y-          dioxy        propy        1-aminobenzol,    wenn man     N-ss    .     y-          i)ioxypropylaminobenzol    mit     Äthylenoxyd          unter    Druck bei erhöhter Temperatur be  handelt.  



       ZVie    nun     weiter    gefunden wurde, erhält       man    in ganz analoger Weise das     1-Methyl-          I-methoxy-3-(ss    -     y-dioxypropyl-oxyäthyl-          t        amino)        -benzol,        wenn        man        das        1-Methyl-4-          nietlioxy-3-(ss    .     ;

  <I>Beispiel:</I>  03 Teile     1-Methyl-4-methoxy-3-(ss    .     y-di-          oxypropylamino)-benzol        (Kpl3    220 bis 221',  F. 127 bis<B>128'</B> aus Methanol) werden mit.  15 Teilen     Äthylenoxyd    6 Stunden bei 150  bis<B>160'</B> im -Rohr erhitzt. Bei der Vakuum  destillation des anfallenden Produktes erhält    man mit etwa<B>80%</B> Ausbeute     1-Methyl-4-          methoxy-3-(ss.        y-dioxypropyl-oxyäthylamino)-          benzol    als wasserhelles, zähflüssiges und in  Wasser leicht lösliches     ()1    vom     Kpu,    237 bis  ?42  .

    Method <SEP> for <SEP> representation <SEP> of <SEP> 1-Rethyl-4-methoxy-3 - (@. <SEP> y-dioxypropyl oxyäthyla, mino) -benzene. According to the process described in the main patent, N-oxyethyl-N-ss is obtained. y-dioxy propy 1-aminobenzene, if you have N-ss. y- i) ioxypropylaminobenzene is treated with ethylene oxide under pressure at elevated temperature.



       As has now been found further, 1-methyl-1-methoxy-3- (ss-y-dioxypropyl-oxyethyl-t amino) -benzene is obtained in a completely analogous manner if 1-methyl-4-nietlioxy-3 - (ss.;

  , -dioxypropylamino) -benzene itiit ltliylenoxy.d treated under pressure at elevated temperature.



  <I> Example: </I> 03 parts of 1-methyl-4-methoxy-3- (ss. Y-di- oxypropylamino) -benzene (Kpl3 220 to 221 ', F. 127 to <B> 128' </ B> from methanol) are with. 15 parts of ethylene oxide heated for 6 hours at 150 to <B> 160 '</B> in a tube. In the vacuum distillation of the product obtained, 1-methyl-4-methoxy-3- (see y-dioxypropyl-oxyethylamino) benzene is obtained with a yield of about 80% as a water-white, viscous and easily in water soluble () 1 from Kpu, 237 to? 42.

   It is intended to be used as an intermediate in the manufacture of azo dyes.
