Description

  

  Verfahren zur Herstellung eines     betainartig    konstituierten     Kondensationsproduktes.       Es wurde     gefunden,    dass man ein wert  volles     betainartig        konstituiertes    Kondensa  tionsprodukt erhält, wenn man     Octadecyl-          chlormethyläther    der Formel  <B>C1837</B> '<B>0 ' CH,</B>     #   <B>Cl</B>  mit einem     Alkalisalz    der     Dimethylamino-          essigsäure    umsetzt.  



  Die neue     betainartig    konstituierte Ver  bindung stellt einen festen Körper dar, der  in Wasser besonders beim Erwärmen löslich  ist. Er ist wegen seiner hohen     Kapillaräkti-          vität    vor allem in der     Textilindustrie    als  Netz-,     Reinigungs-,        Dispergier-    und     Avivier-          mittel    verwendbar.

   Auch zusammen mit  andern     Textilhilfsmitteln,    wie Seife,     Alkohol-          sulfonaten,        Fettsäurekondensationsprodukten,          Alkylnaphthalinsulfonsäuren    und andern  kann das Produkt Verwendung finden.  



  Bei der Umsetzung des     Octadecylehlor-          m.ethyläthers    mit dem Salz der Dimethyl-         ammoessigsäure    kann die     Verwendung    eines  geeigneten     Lösungsmittels,    z. B. Alkohol,  vorteilhaft     sein.     



       Beispiele:     1. Eine schwach erwärmte     Lösung    von  11     Gewichtsteilen        Dimethylaminoessigsäure     in 200 Gewichtsteilen Alkohol wird mit 12  Gewichtsteilen Natronlauge von 40       B6    und  dann sofort mit 32 Gewichtsteilen     Octadecyl-          chlormethyläther    versetzt. Nach     kurzem     Stehen wird das gebildete Kochsalz     abfiltriert     und das     alkoholische    Filtrat im     Vakuum    bei  40   eingedampft.

   Der schmierige Rückstand       wird    mit kaltem Aceton     angeteigt    und der  in Aceton unlösliche Körper abgesaugt. Die  ser wird sodann aus     Cyclohexan    umkristalli  siert. Die neue     Verbindung    stellt einen  festen, farblosen     Körper    dar, der sich in  heissem Wasser klar löst. Das     Produkt    be  sitzt folgende Konstitution:    
EMI0002.0001     
    2.

   Man erwärmt 63 g einer     wässrigen,     50prozentigen Lösung von     tlimethylamino-          essigsaurem    Kalium auf etwa<B>65'</B> und lässt  unter Rühren 62 g geschmolzenen     Octadecy        1-          chlormethyläther        zutropfen.    Dabei tritt Er  wärmung auf, die jedoch 85   nicht überstei  gen soll. Nach der Zugabe des     Octadecyl-          chlormethyläthers    erwärmt man das Ganze  noch 1     Stunde    auf<B>80-85'</B> und lässt erkal  ten. Man erhält eine in Wasser     lösliehe    farb  lose Paste.



  Process for the production of a betaine-like constituted condensation product. It has been found that a valuable betaine-like constituted condensation product is obtained if octadecylchloromethyl ether of the formula <B> C1837 </B> '<B> 0' CH, </B> # <B> Cl </ B is used > Reacts with an alkali salt of dimethylamino acetic acid.



  The new betaine-like connection is a solid body that is soluble in water, especially when heated. Because of its high capillary activity, it can be used primarily in the textile industry as a wetting, cleaning, dispersing and softening agent.

   The product can also be used together with other textile auxiliaries, such as soap, alcohol sulfonates, fatty acid condensation products, alkylnaphthalene sulfonic acids and others.



  When reacting the Octadecylehlor- m.ethyläthers with the salt of dimethyl ammoacetic acid, the use of a suitable solvent, eg. B. alcohol, be advantageous.



       Examples: 1. A slightly heated solution of 11 parts by weight of dimethylaminoacetic acid in 200 parts by weight of alcohol is mixed with 12 parts by weight of 40 B6 sodium hydroxide solution and then immediately with 32 parts by weight of octadecyl chloromethyl ether. After standing for a short time, the sodium chloride formed is filtered off and the alcoholic filtrate is evaporated at 40 in a vacuum.

   The greasy residue is made into a paste with cold acetone and the body which is insoluble in acetone is suctioned off. This water is then recrystallized from cyclohexane. The new connection represents a solid, colorless body that dissolves clearly in hot water. The product has the following constitution:
EMI0002.0001
    2.

   63 g of an aqueous, 50 percent strength solution of potassium thimethylamino-acetic acid are heated to about 65 'and 62 g of molten octadecyl 1-chloromethyl ether are added dropwise with stirring. It warms up, but it should not exceed 85. After the addition of the octadecyl chloromethyl ether, the whole is heated to 80-85 'for 1 hour and allowed to cool. A colorless paste which is soluble in water is obtained.
