Description

  

  Verfahren zur Herstellung eines harzartigen Kondensationsproduktes.    Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines harzartigen  Kondensationsproduktes, dadurch gekenn  zeichnet, dass man     N-Methylpyrrol    mit Form  aldehyd derart     kondensiert,    dass man ein       Kondensationsprodukt    erhält, welches ein  schwarzes, hartes Harz ist, das eine sehr gute  Beständigkeit gegen Laugen und Säuren be  sitzt.  



       Beispiel:     8 Teile     N-Methylpyrrol    der Formel:  
EMI0001.0006     
    werden mit 15 Teilen einer 30 %     igen    wässeri  gen     Formaldehydlösung    gemischt. Unter star-         ker    Erwärmung beginnt die Harzbildung so  fort und es scheidet sich ein schwach gefärb  tes Produkt ab. Nach mehrstündigem Erwär  men auf dem Wasserbad wird das Wasser bei  etwa<B>90'</B> C     abgedunstet    und der     Rückstand     noch einige Zeit auf etwa 130   C erhitzt.



  Process for the preparation of a resinous condensation product. The present patent relates to a process for the production of a resinous condensation product, characterized in that N-methylpyrrole is condensed with formaldehyde in such a way that a condensation product is obtained which is a black, hard resin which has very good resistance to alkalis and Acids.



       Example: 8 parts of N-methylpyrrole of the formula:
EMI0001.0006
    are mixed with 15 parts of a 30% aqueous formaldehyde solution. Resin formation begins immediately under intense heating and a slightly colored product separates out. After several hours of heating on the water bath, the water is evaporated at about <B> 90 '</B> C and the residue is heated to about 130 C for some time.
