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-1-benzyl-mono    -1,4 -     butan-          dioläther    vom Kp, 152-155 , erhalten durch  Umsetzen von     2,4,6-Triisopropyl-l-benzyl-          chlorid    mit der     Mononatriumverbindung    von       1,4-Butandiol        in    Gegenwart von überschüs  sigem     Butandiol,

      mit 10     Mol        Äthylenoxyd     umsetzt.  



  Der so erhaltene Polyäther ist     ein    in  Wasser leicht lösliches Produkt und     eignet     sich vorzüglich als Wollwaschmittel.    <I>Beispiel:</I>    Man leitet in 306 Teile     2,4,6-Triisopro-          pyl-l-benzyl-mono-l.,4-butandioläther    (erhal  ten aus     2,4,6-Triisopropyl    -1-     benzylchlorid          und    der     Mononatriumverbindung    von     1,4-Bu-          tandiol    in Gegenwart von überschüssigem       Butandiol,    farblose viskose Flüssigkeit, Kp,    152-155 )

   nach Zugabe von 3     Teilen        Na-          triummethylat    so lange bei 120-130      Athy-          lenoxyd        ein,    bis die Aufnahme 440 Teile  = 10     Mol    beträgt.



  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-1,4-butanediol ether of bp 152-155 is obtained by reaction of 2,4,6-triisopropyl-1-benzyl chloride with the monosodium compound of 1,4-butanediol in the presence of excess butanediol,

      with 10 moles of ethylene oxide.



  The polyether obtained in this way is a product that is readily soluble in water and is particularly suitable as a detergent for wool. <I> Example: </I> In 306 parts of 2,4,6-triisopropyl-1-benzyl-mono-1,4-butanediol ether (obtained from 2,4,6-triisopropyl -1- benzyl chloride and the monosodium compound of 1,4-butanediol in the presence of excess butanediol, colorless viscous liquid, bp 152-155)

   after adding 3 parts of sodium methylate, add 120-130 ethylene oxide until the uptake is 440 parts = 10 mol.
