Description

  

  Verfahren zur Herstellung eines Polyäthers.    Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines Polyäthers,  dadurch gekennzeichnet,     dass    man 1     Mol     2,4, 6     -Triisopropyl-l-benzyl-mono-glykoläther     vom     gp3",    158-162 , hergestellt durch Ein  wirkung von 2,4,6 -     Triisopropyl    -1-     benzyl-          chlorid    auf     Natriumglykolat    in Gegenwart  von überschüssigem Glykol, mit 8     Mol        Athy-          lenoxyd    umsetzt.  



  Der so erhaltene Polyäther ist ein in  Wasser leicht lösliches öliges Produkt; es be  sitzt eine gute Netz- und Waschwirkung und  soll als Textilhilfsmittel Verwendung finden.  <I>Beispiel:</I>  278 Teile 2,4,6     -Triisopropyl-l-benzyl-          mono-glykoläther    vom     gps,    158-162 , her  gestellt durch Einwirkung von     2,4,6-Trüso-          propyl-l-benzylchlorid    auf     Natriumglykolat     in Gegenwart von überschüssigem Glykol,  und 2 Volumenanteile einer 50%igen Na  tronlauge werden gemischt und das über-         schüssige    Wasser durch Erwärmen im Va  kuum bei<B>100'</B> entfernt.

   Dann lässt man       Äthylenoxyd    bei     140-150'    bis zur Auf  nahme von 352 Teilen, entsprechend 8 Mole  külen,     Äthylenoxyd        einwirken.  



  Process for the production of a polyether. The present patent relates to a process for the production of a polyether, characterized in that 1 mol of 2,4,6-triisopropyl-1-benzyl-mono-glycol ether from gp3 ", 158-162, produced by action of 2,4 6 - triisopropyl -1-benzyl chloride on sodium glycolate in the presence of excess glycol, with 8 moles of ethylene oxide.



  The polyether thus obtained is an oily product which is readily soluble in water; it has a good wetting and washing effect and is said to be used as a textile auxiliary. <I> Example: </I> 278 parts of 2,4,6-triisopropyl-l-benzyl-mono-glycol ether from gps, 158-162, produced by the action of 2,4,6-triisopropyl-l- Benzyl chloride on sodium glycolate in the presence of excess glycol and 2 parts by volume of a 50% strength sodium hydroxide solution are mixed and the excess water is removed by heating in a vacuum at <B> 100 '</B>.

   Ethylene oxide is then allowed to act at 140-150 'up to 352 parts, corresponding to 8 moles, of ethylene oxide.
