Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes. Es wurde gefunden, dass man zu einem neuen Kondensationsprodukt gelangt, wenn man N-Methyl-u-heptadecyl-benzimidazol- chlorhydratmit rnethylolacetamidsulforisaurem Natrium umsetzt.
Die Umsetzung wird zweckmässig in Gegen wart von konzentrierter Schwefelsäure vor genommen.
Das neue Kondensationsprodukt bildet in Form des Natriumsalzes eine feste Masse, die in Wasser unter starkem Schäumen lös lich ist und stark kapillaraktive Eigenschaf ten besitzt. Es kann als Textilhilfsstoff ver wendet werden.
<I>Beispiel:</I> 4 Gewichtsteile N-Methyl-ss-heptadecyl- benzimidazolchlorhydrat werden in 20 Ge wichtsteilen konzentrierter Schwefelsäure in der Kälte gelöst. Unter Rühren werden nach und nach bei 15-20' 2,5 Gewichtsteile fein pulverisiertes methylolacetamidsulfonsaures Natrium zugegeben. Nach 30stündigem Rüh ren bei gewöhnlicher Temperatur ist eine Probe in Wasser nach dem Neutralisieren mit Soda klar löslich. Durch Neutralisieren der erhaltenen Säure mit Natronlauge kann das Natriumsalz erhalten werden, das in Wasser unter starkem Schäumen löslich ist und stark kapillaraktive Eigenschaften besitzt.
Process for the production of a new condensation product. It has been found that a new condensation product is obtained if N-methyl-u-heptadecyl-benzimidazole chlorohydrate is reacted with sodium methylolacetamidesulfurate.
The reaction is expediently taken in the presence of concentrated sulfuric acid.
The new condensation product forms a solid mass in the form of the sodium salt, which is soluble in water with strong foaming and has strong capillary-active properties. It can be used as a textile auxiliary.
<I> Example: </I> 4 parts by weight of N-methyl-ss-heptadecyl benzimidazole chlorohydrate are dissolved in 20 parts by weight of concentrated sulfuric acid in the cold. While stirring, 2.5 parts by weight of finely powdered sodium methylolacetamidesulfonic acid are gradually added at 15-20 '. After 30 hours of stirring at normal temperature, a sample is clearly soluble in water after neutralization with soda. By neutralizing the acid obtained with sodium hydroxide solution, the sodium salt can be obtained, which is soluble in water with strong foaming and has strong capillary-active properties.
