Description

  

  Verfahren zur Herstellung eines substituierten     2.6-Diamino-triazins-1.3.5.       Vorliegendes Patent bezieht sich auf ein       Verfahren,    zur Herstellung eines substituier  ten     2.6-Diamino-triazins-1.3.5,    dadurch ge  kennzeichnet, dass man ein Gemisch von     Di-          cyandiamid    mit     N-Cyandibenzylamin,    zweck  mässig unter Zusatz einer stark basischen  Verbindung, auf höhere Temperatur erhitzt.  



  Das so erhaltene, bisher unbekannte,       2.6-Diamino-4-dibenzylamino-triazin-1.3.5    ist  ein farbloses Pulver, das,     aus        Butanol    um  kristallisiert, bei 217-218  schmilzt. Es soll  als     Zwischenprodukt    zur Herstellung von  harzartigen Kondensationsprodukten Ver  wendung finden.  



  <I>Beispiel:</I>  84 Teile     Dicyandiamid    werden in etwa  500 Teilen     N-Cyandibenzylamin    unter Zu  satz von etwa 5 Teilen     Piperidin    etwa 3  Stunden auf 200-205  erhitzt. Man trennt  vom Überschuss des     Cyandibenzylamins    ab  und erhält 260 Teile     (857o    der Theorie) an       2.6-Diamino-4-dibenzylamino-triazin-1.3.5.  



  Process for the preparation of a substituted 2,6-diamino-triazine-1.3.5. The present patent relates to a process for the preparation of a substituted 2,6-diamino-triazine-1.3.5, characterized in that a mixture of dicyandiamide with N-cyandibenzylamine, advantageously with the addition of a strongly basic compound, is used heated higher temperature.



  The previously unknown 2,6-diamino-4-dibenzylamino-triazine-1.3.5 obtained in this way is a colorless powder which, when crystallized from butanol, melts at 217-218. It is said to be used as an intermediate for the production of resinous condensation products.



  <I> Example: </I> 84 parts of dicyandiamide are heated to 200-205 for about 3 hours in about 500 parts of N-cyandibenzylamine with the addition of about 5 parts of piperidine. The excess cyandibenzylamine is separated off and 260 parts (8570 of theory) of 2,6-diamino-4-dibenzylamino-triazine-1.3.5 are obtained.

PATENTANSPRUCH: Verfahren zur Herstellung eines substi tuierten 2.6-Diamino-triazins-1.3.5, dadurch gekennzeichnet, dass man ein Gemisch von Dicyandiamid mit N-Cyandibenzylamin auf höhere Temperatur erhitzt. Das so erhaltene, bisher unbekannte, 2.6-Diamino-4-dibenzylamino-triazin-1.3.5 ist ein farbloses Pulver, das, aus Butanol um kristallisiert, bei 217-2l8 schmilzt. Es soll als Zwischenprodukt zur Herstellung von harzartigen Kondensationsprodukten Ver wendung finden. PATENT CLAIM: A process for the production of a substituted 2,6-diamino-triazines-1.3.5, characterized in that a mixture of dicyandiamide with N-cyandibenzylamine is heated to a higher temperature. The hitherto unknown 2,6-diamino-4-dibenzylamino-triazine-1.3.5 obtained in this way is a colorless powder which, when recrystallized from butanol, melts at 217-218. It is said to be used as an intermediate for the production of resinous condensation products. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man dem Reaktions gemisch eine stark basische Verbindung zu setzt. SUBSTANTIAL CLAIM: Process according to claim, characterized in that a strongly basic compound is added to the reaction mixture.
