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     -Triisopropylbenzol    -1-     sulfomethylätha-          nolamid    vom Schmelzpunkt 72 , hergestellt  durch Umsetzung von     2,4,6-Triisopropylben-          zol-l-sulfochlorid    mit     Methylmonoäthanol-          amin    in Gegenwart von Soda, mit 20     Mol          Äthylenoxyd    umsetzt.  



  Der so erhaltene Polyäther ist ein in  Wasser leicht lösliches öliges Produkt und  besitzt vorzügliche     emulgierende    Eigen  schaften.  



  <I>Beispiel:</I>       In    eine     Mischung    von 341 Teilen     2,4,6-          Triisopropylbenzol-l-sulfomethyläthanolamid     vom Schmelzpunkt 72 , hergestellt durch  Umsetzung von     2,4,6-Triisopropylbenzol-l-          sulfochlorid    mit     Methylmonoäthanolamin    in  Gegenwart von Soda, und 3 Teilen Natrium-         methylat    leitet man bei 130-140  Äthylen  oxyd bis zur Aufnahme von 880     Teilen,    ent  sprechend 20 Molekülen, 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-triisopropylbenzene -1-sulfomethylethanolamide with a melting point of 72, produced by reacting 2,4,6-triisopropylbenzene -l-sulfochloride with methylmonoethanol amine in the presence of soda, with 20 moles of ethylene oxide.



  The polyether obtained in this way is an oily product which is readily soluble in water and has excellent emulsifying properties.



  <I> Example: </I> In a mixture of 341 parts of 2,4,6-triisopropylbenzene-1-sulfomethylethanolamide with a melting point of 72, prepared by reacting 2,4,6-triisopropylbenzene-1-sulfochloride with methylmonoethanolamine in the presence of Soda and 3 parts of sodium methylate are introduced with 130-140 ethylene oxide up to 880 parts, corresponding to 20 molecules, being absorbed.
