Description
Verfahren zur Darstellung eines stickstoff- und schwefelhaltigen Kondensationsproduktes. Es wurde ein Verfahren zur Darstellung eines sticlistoff- und schwefelhaltigen Kon densationsproduktes gefunden, welches da durch gekennzeichnet ist, .dass man Pyridin mit 1-FIalogen-2-oxypropan-3-sulfonsäure bei erhöhter Temperatur kondensiert.
EMI0001.0007
Bei Verwendung von 2 Mol Base und 1 Mol der Halo, nalkylsulfonsäure erhält man das halogenwasserstoffsaure Salz .der tertiären Base als Nebenprodukt, aus dem die Base zur weiteren Verwendung wieder gewonnen werden kann.
Die Kondensation Die Umsetzung verläuft wahrscheinlich unter Bildung eines Kondensationsproduktes mit betainähnlicher Bindung der SuHon- säuregruppe an das tertiäre Stickstoffatom, etwa nach folgendem Schema: erfolgt sehr leicht und wird bei erhöhter Temperatur durchgeführt.
Das entstehende Kondensationsprodukt ist gegen Säuren ausserordentlich unempfindlich, gegen schwache Alkalien beständig, von kon zentrierten Alkalilaugen wird. es unter Dun- kelfärbung gespalten.
Es eignet sich zur Herstellung von Textilhilfsmitteln. Weiter kann man es auch mit Vorteil beim. Druck von Küpenfarbstoffen zur Erzielung einer guten Fi.gation, hoher Ergiebigkeit und guter Egalität mit Erfolg verwenden.
Beispiel: 175 Gewichtsteile 1-Chlor-2-oxypropan-3- sulfonsäure werden mit 500 Gewichtsteilen Pyridin unter Rückfluss gerührt und 6 Stun- den zum Sieden erhitzt. Schon nach einer Stunde beginnt eine Kristallabscheidung, deren Menge immer mehr zunimmt. Das aus gefallene Kondensationsprodukt - 210 Ge wichtsteile - wird abgesaugt und bildet nach einmaligem Umkristallisieren aus 90%igem Alkohol farblose, derbe Täfelchen, die bei 246 bis 247' schmelzen.
Im Rückstand der ganz eingedampften Pyridinmutterlauge bleibt das salzsaure Pyridin. Die Analyse des Kondensationsproduktes ergab:
EMI0002.0026
C <SEP> = <SEP> 44,3% <SEP> 44,4%
<tb> H <SEP> = <SEP> 5,4
<tb> N <SEP> = <SEP> 6,7
<tb> S <SEP> = <SEP> 14,9% <SEP> 15,1
<tb> C1 <SEP> = <SEP> 0 Die Analysenwerte stimmen mit der oben angegebenen Konstitution der neuen Verbin dung gut überein.
Process for the preparation of a nitrogen- and sulfur-containing condensation product. A process for the preparation of a sticlistoff- and sulfur-containing condensation product has been found which is characterized by the fact that pyridine is condensed with 1-halogen-2-oxypropane-3-sulfonic acid at elevated temperature.
EMI0001.0007
If 2 moles of base and 1 mole of the halo, nalkylsulfonic acid are used, the hydrohalic acid salt of the tertiary base is obtained as a by-product from which the base can be recovered for further use.
The condensation The reaction probably proceeds with the formation of a condensation product with a betaine-like bond of the SuHonic acid group to the tertiary nitrogen atom, roughly according to the following scheme: takes place very easily and is carried out at elevated temperature.
The resulting condensation product is extremely insensitive to acids, resistant to weak alkalis, and is concentrated by alkaline solutions. it split darkly.
It is suitable for the production of textile auxiliaries. You can also do it with advantage at. Use the pressure of vat dyes with success to achieve good fixation, high yield and good levelness.
Example: 175 parts by weight of 1-chloro-2-oxypropane-3-sulfonic acid are stirred with 500 parts by weight of pyridine under reflux and heated to boiling for 6 hours. After just one hour, crystals begin to separate, the amount of which increases more and more. The condensation product that has precipitated - 210 parts by weight - is filtered off with suction and, after recrystallizing once from 90% alcohol, forms colorless, coarse tablets which melt at 246 to 247 '.
The hydrochloric acid pyridine remains in the residue of the completely evaporated pyridine mother liquor. The analysis of the condensation product showed:
EMI0002.0026
C <SEP> = <SEP> 44.3% <SEP> 44.4%
<tb> H <SEP> = <SEP> 5.4
<tb> N <SEP> = <SEP> 6.7
<tb> S <SEP> = <SEP> 14.9% <SEP> 15.1
<tb> C1 <SEP> = <SEP> 0 The analysis values agree well with the constitution of the new compound given above.
