Description
Verfahren zur Herstellung eines harzartigen Kondensationsproduktes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines harzartigen Kondensationsproduktes, dadurch gekenn zeichnet, dass man mindestens 1 Mol. Form aldehyd mit 1 Mol. 2.4-Dihydrazidochina, zolin kondensiert.
Das so erhaltene Kondensationsprodukt ist ein wasserbeständiges, hartes, farbloses, harzartiges Produkt, das zur Herstellung von Pressmassen und Pressartikeln, von Leim und Klebstoffen und von Lacken und Filmen Verwendung finden kann.
Beispiel: 30 Teile 2.4-Dihydrazidochinazolin der Formel
EMI0001.0011
werden mit etwas Wasser zu einem dünnen Teig verrührt, sodann gibt man etwa 2 Teile Pyridin zu, erwärmt auf 60 bis 70 C, setzt etwa 50 Teile 30%igen Formaldehyd zu und erhitzt bis alles gelöst ist. Sodann wird die Lösung im Vakuum eingedampft. Das zu rückbleibende Harz wird bei Temperaturen zweckmässig über<B>100'</B> C gehärtet.
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 at least 1 mole of formaldehyde is condensed with 1 mole of 2,4-dihydrazidoquina, zoline.
The condensation product obtained in this way is a water-resistant, hard, colorless, resin-like product which can be used for the production of molding compounds and molded articles, glue and adhesives, and varnishes and films.
Example: 30 parts of 2,4-dihydrazidoquinazoline of the formula
EMI0001.0011
are mixed with a little water to form a thin dough, then about 2 parts of pyridine are added, heated to 60 to 70 ° C., about 50 parts of 30% formaldehyde are added and the mixture is heated until everything has dissolved. The solution is then evaporated in vacuo. The remaining resin is expediently cured at temperatures above <B> 100 </B> C.
