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     Kp3,,    158-162 , hergestellt durch Ein  wirkung von     2,4,6-Triisopropyl-l-benzylchlo-          rid    auf     Natriumglykolat    in Gegenwart von  überschüssigem Glykol, mit 15     Mol        Äthylen-          Oxyd    umsetzt.  



  Der so erhaltene Polyäther ist von salben  artiger Beschaffenheit, gut in Wasser löslich  und     eignet    sich vorzüglich zur     Spaltung    von       wässerigen        Roherdölemulsionen.     



  <I>Beispiel:</I>  In     eine    Mischung von 278 Teilen     2,4,6-          Triisopropyl-l-benzyl-mono-glykoläther    vom       Kp3,5        158-l.62 ,    hergestellt durch     Einwir-          kung    von     2,4,6-Triisopropyl-l-benzylchlorid     auf     Natriumglykolat    in Gegenwart von über-         schüssigem    Glykol, und 2 Teilen     Natrium-          methylat    leitet man bei     120-130     660 Teile       Äthylenoxyd,    entsprechend 15 Molekülen,  unter Rühren ein.



  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 of Kp3 ,, 158-162, produced by action of 2,4 , 6-triisopropyl-1-benzyl chloride on sodium glycolate in the presence of excess glycol, with 15 moles of ethylene oxide.



  The polyether obtained in this way has an ointment-like consistency, is readily soluble in water and is particularly suitable for breaking down aqueous crude oil emulsions.



  <I> Example: </I> In a mixture of 278 parts of 2,4,6-triisopropyl-1-benzyl-mono-glycol ether with a boiling point of 3.5 158-l.62, produced by the action of 2.4, 6-Triisopropyl-1-benzyl chloride on sodium glycolate in the presence of excess glycol and 2 parts of sodium methylate are introduced at 120-130 660 parts of ethylene oxide, corresponding to 15 molecules, with stirring.
