Die Herstellung der erfindungsgemäß zu verwendenden Umsetzungsprodukte sei nachstehend an Hand der Herstellung eines Umsetzungsproduktes aus Epichlorhydrin und y, /-Diaminopropyl-methylamin näher erläutert:The preparation of the reaction products to be used according to the invention will be explained in more detail below with reference to the preparation of a reaction product from epichlorohydrin and γ, / -diaminopropyl-methylamine:
Eine Lösung von 145 g γ, y'-Diaminopropylmethylamin (1 Mol) in 362 ml Wasser wird innerhalb 1 Stunde bei 30° C unter Rühren und unter Kühlen mit 80,5 g Epichlorhydrin (0,87 Mol) versetzt. Dann erhöht man die Temperatur des Reaktionsgemisches innerhalb 1Zs Stunde auf 40° C und rührt die Mischung bei dieser Temperatur noch so lange, bis die Viskosität auf etwa 7OcP angestiegen ist; dies ist nach etwa 80 Minuten der Fall. Hierauf setzt man dem Reaktionsgemisch 145 ml Wasser zu; dadurch sinkt die Viskosität auf ungefähr 40 cP. Nunmehr erwärmt man die Mischung bei 40° C so lange, bis die Viskosität der Lösung auf etwa 120 cP angestiegen ist. Diese Viskosität ist erreicht nach etwa 2V2 Stunden, gerechnet von der Zugabe der 145 ml Wasser, bzw. nach 4 Stunden, gerechnet von dem Ende der Zugabe des Epichlorhydrins. Abschließend fügt man zu der Lösung noch 171 ml Wasser hinzu. Die so bereitete Lösung enthält 25°/o des Umsetzungsproduktes aus Epichlorhydrin und 3>,/-Diaminopropylmethylamin und besitzt eine Viskosität von 145 cP bei 25° C.80.5 g of epichlorohydrin (0.87 mol) are added to a solution of 145 g of γ, γ'-diaminopropylmethylamine (1 mol) in 362 ml of water at 30 ° C., while stirring and with cooling, over the course of 1 hour. The temperature of the reaction mixture is then increased to 40 ° C. in the course of 1 hour and the mixture is stirred at this temperature until the viscosity has risen to about 70 cP; this is the case after about 80 minutes. Then 145 ml of water are added to the reaction mixture; this reduces the viscosity to around 40 cP. The mixture is now heated at 40 ° C. until the viscosity of the solution has risen to about 120 cP. This viscosity is reached after about 2/2 hours, calculated from the addition of the 145 ml of water, or after 4 hours, calculated from the end of the addition of the epichlorohydrin. Finally, 171 ml of water are added to the solution. The solution prepared in this way contains 25% of the reaction product of epichlorohydrin and 3>, / - diaminopropylmethylamine and has a viscosity of 145 cP at 25 ° C.
Ein Produkt mit praktisch gleichen Eigenschaften erhält man, wenn man an Stelle von 0,87 Mol Epichlorhydrin 0,9 Mol a-Dichlorhydrin zum Einsatz bringt. Die Bildung des Umsetzungsproduktes erfolgt in diesem Fall langsamer, kann jedoch gewünschtenfalls durch Zusatz von Kaliumhydroxyd oder Natriumhydroxyd in Mengen bis zu 0,9 Mol wesentlich beschleunigt werden.A product with practically the same properties is obtained if instead of 0.87 mol of epichlorohydrin 0.9 mol of a-dichlorohydrin is used. The conversion product is formed in this case more slowly, but can if desired by adding potassium hydroxide or sodium hydroxide can be significantly accelerated in amounts up to 0.9 mol.
