Description

  

  Verfahren zur Herstellung eines harzartigen Kondensationsproduktes.    Vorliegendes     Patent    bezieht sich auf ein  Verfahren zur Herstellung eines harzartigen       Kondensationsproduktes,    dadurch gekenn  zeichnet, dass man     2,5-Dimethylpyrrol    mit  Formaldehyd derart kondensiert, dass man ein       Kondensationsprodukt    erhält, welches ein  dunkles, undurchsichtiges Harz darstellt, das  in Wasser und organischen Lösungsmitteln  unlöslich ist.  



       Beis@eZ:     10 Teile     2,5-Dimethylpyrrol    der Formel:  
EMI0001.0007     
    werden mit 50 Teilen einer 30%igen Form  aldehydlösung und 50 Teilen Alkohol kurze  Zeit am     Rückflusskühler    erwärmt und die  klare Lösung hierauf zur Trockne verdampft.



  Process for the preparation of a resinous condensation product. The present patent relates to a process for the preparation of a resinous condensation product, characterized in that 2,5-dimethylpyrrole is condensed with formaldehyde in such a way that a condensation product is obtained which is a dark, opaque resin that is insoluble in water and organic solvents is.



       Beis @ eZ: 10 parts of 2,5-dimethylpyrrole of the formula:
EMI0001.0007
    are heated with 50 parts of a 30% formaldehyde solution and 50 parts of alcohol on the reflux condenser for a short time and the clear solution is then evaporated to dryness.
