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.
