Description

Verfahren zur Herstellung von Kondensationsprodukten aus Harnstoff und Alkoholen oder Ketonen In der Patentschrift 510,428 wurde der Umsatz von reduzierend wirkenden Metallen mit den Kondensationsprodukten aus Harnstoffen und mehrwertigen Alkoholen mit oder ohne Zusatz von nicht harnstoffartigen Aminoverbindungen beschrieben.Process for the production of condensation products from urea and alcohols or ketones In the patent 510,428 the conversion of reducing active metals with the condensation products of ureas and polyvalent ones Described alcohols with or without the addition of non-urea-like amino compounds.

Es ist nun gefunden worden, daß diese Umsetzungsprodukte mit Formaldehyd oder formaldehydabspaltenden Stoffen zur Reaktion zu bringen sind und Produkte mit neuen Eigenschaften entstehen.It has now been found that these reaction products with formaldehyde or formaldehyde-releasing substances are to be brought to reaction and products are included new properties arise.

Die Reaktionsprodukte stellen zähflüssige oder harzartige Substanzen dar, welche, sofern ihre Gestehung bei niederen Temperaturen erfolgt ist, sich leicht in Wasser und hydroxylhaltigen Lösungsmitteln lösen, jedoch durch Einwirkung höherer Temperatur in diesem Lösungsmittel unlöslich werden.The reaction products are viscous or resinous substances which, if their formation took place at low temperatures, is easy Dissolve in water and hydroxyl-containing solvents, but by exposure to higher Temperature become insoluble in this solvent.

Diese Produkte können als Kunstharze für sich allein oder als Zusatzmittel gemeinsam mit anderen Stoffen Verwendung finden.These products can be used as synthetic resins on their own or as additives used together with other substances.

Beispiele i. Zoo Gewichtsteile eines nach Patent 51o428 aus 9,5 Gewichtsteilen Butylenglycol, 35; Gewichtsteilen Harnstoff, 6o Gewichtsteilen Toluolsulfamid und 1,5 Gewichtsteilen Magnesiummetall erzielten öligen Kondensationsproduktes werden unter Rückfluß 8 Stunden mit 32o Gewichtsteilen 3oprozentiger Formaldehydlösung gekocht. Man erhält eine klare, zähflüssige Masse, welche leicht löslich in Wasser, Alkoholen u. dgl. ist. Nach Erhitzen auf höhere Temperatur tritt Unlöslichwerden ein.Examples i. Zoo parts by weight of one according to patent 51o428 made from 9.5 parts by weight butylene glycol, 35; Parts by weight of urea, 60 parts by weight of toluenesulfamide and 1.5 parts by weight of magnesium metal obtained oily condensation product are refluxed for 8 hours with 32o parts by weight of 3% formaldehyde solution. A clear, viscous mass is obtained which is easily soluble in water, alcohols and the like. After heating to a higher temperature, it becomes insoluble.

2. 32o Gewichtsteile des in Beispiel i nach Patent 510 428 erhaltenen Produktes werden mit 8o Gewichtsteilen Paraformaldehyd bei 55 bis 65' gerührt. Nach 15 bis 2o Stunden ist vollständige Umsetzung und Lösung erfolgt, und man erhält eine sehr zähflüssige Masse, welche in Wasser und Alkoholen löslich ist. Bei höherer Temperatur wird das Produkt unlöslich.2. 32o parts by weight of the product obtained in Example I according to Patent 510,428 are stirred with 8o parts by weight of paraformaldehyde at 55 and 65 '. After 15 to 20 hours, complete conversion and dissolution has taken place, and a very viscous mass is obtained which is soluble in water and alcohols. At higher temperatures the product becomes insoluble.

3. 3"2o Gewichtsteile des in Beispiel i nach Patent 51o q.28 erhaltenen Produktes werden mit 8o Gewichtsteilen Methylolharnstoff unter Rühren bei 6o bis 7o° umgesetzt. Man erhält ein Produkt, das demjenigen des Beispiels 2 sehr ähnlich ist.3. 3 "2o parts by weight of that obtained in example i according to patent 51o q.28 Product are with 8o parts by weight of methylolurea with stirring at 6o to 7o ° implemented. A product is obtained which is very similar to that of Example 2 is.
