Description

  

      Zusatzpatent    zum hauptpatent Nr.     2e2'9608.       Verfahren zur Herstellung eines basischen Kondensationsproduktes.    Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines basischen  Kondensationsproduktes. dadurch gekenn  zeichnet, dass man     Trimethylolmelamin    mit       Monoäthanolamin    im molekularen Verhältnis  von 3 : 2 umsetzt und auf das Reaktionspro  dukt     \/3        Mol    Formaldehyd einwirken lässt.  



  Das so erhaltene Kondensationsprodukt  ergibt mit Wasser klare viskose Lösungen  und liefert, auch nach Zusatz von sauren Ka  talysatoren, lang haltbare     Imprägn.ierungs-          lösungen    für Textilien.  



  <I>Beispiel:</I>  126 kg     Melamin    (1     Mol)    werden mit  243 kg schwach alkalisch eingestelltem  37%igem Formaldehyd (3     Mol)    bei 70 bis  75  gelöst. Nach einer     Erhitzung?zeit    von  etwa 15 Minuten gibt man 43,8 kg 94%iges       Monoäthanolamin        (2/3        Mol)    zu und hält die  Temperatur noch etwa 10 Minuten zwischen  70 und 75 .     Sodann    fügt man zu der Lösung    55 kg 37%igen neutralen Formaldehyd     (2/3          Mol)    und hält die Temperatur noch kurze  Zeit bei 75 .

   Die von geringen Mengen Ver  unreinigungen     abfiltrierte    klare viskose Lö- 2  sung bleibt auch beim Stehen im kühlen  Raum längere Zeit flüssig.



      Additional patent to the main patent No. 2e2'9608. Process for the production of a basic condensation product. The present patent relates to a process for preparing a basic condensation product. characterized in that trimethylolmelamine is reacted with monoethanolamine in a molecular ratio of 3: 2 and the reaction product / 3 mol of formaldehyde is allowed to act.



  The condensation product obtained in this way gives clear viscous solutions with water and provides long-lasting impregnation solutions for textiles, even after the addition of acidic catalysts.



  <I> Example: </I> 126 kg of melamine (1 mol) are dissolved with 243 kg of weakly alkaline 37% formaldehyde (3 mol) at 70 to 75. After a heating time of about 15 minutes, 43.8 kg of 94% monoethanolamine (2/3 mol) are added and the temperature is maintained between 70 and 75 for about 10 minutes. 55 kg of 37% neutral formaldehyde (2/3 mol) are then added to the solution and the temperature is kept at 75 for a short time.

   The clear viscous solution filtered off from small amounts of impurities remains liquid for a long time even when standing in a cool room.
