Description

Verfahren zur Herstellung von Erzeugnissen aus Formaldehyd, weiteren Carbonylverbindungen, Ammoniumsalzen und Harnstoff In dem Patent 688 302 ist ein Verfahren zur Herstellung von Erzeugnissen durch Umsetzung von Formaldehyd, anderen Aldehyden und Ammoniumsalzen beschrieben.Process for the production of products from formaldehyde, other carbonyl compounds, ammonium salts and urea The patent 688 302 describes a process for the production of products by converting formaldehyde, other aldehydes and ammonium salts.

Im Zusatzpatent 730 337 ist beschrieben, daß die nach dem Patent 688302 erhältlichen Erzeugnisse erheblich verbessert werden können, wenn man die Umsetzung in Gegenwart von Harnstoff vornimmt oder die nach dem Verfahren des Hauptpatents erhältlichen Erzeugnisse noch mit Harnstoff umsetzt, wobei man solche Mengen Harnstoff verwendet, daß noch lösliche Erzeugnisse entstehen. In dem weiteren Zusatzpatent 745 099 ist gezeigt worden, daß man ebenfalls Erzeugnisse von ausgezeichneten Eigenschaften erhält, wenn man bei der Herstellung der Erzeugnisse aus Formaldehyd, anderen Aldehyden und Ammoniumsalzen wasserlösliche Kondensationsprodukte aus Formaldehyd und Harnstoff mitverwendet.In the additional patent 730 337 it is described that the products obtainable according to the patent 688302 can be considerably improved if the reaction is carried out in the presence of urea or if the products obtainable by the process of the main patent are still reacted with urea, using such amounts of urea, that soluble products are still formed. In the further additional patent 745 099 it has been shown that products with excellent properties are also obtained if water-soluble condensation products of formaldehyde and urea are also used in the manufacture of products from formaldehyde, other aldehydes and ammonium salts.

Es wurde nun gefunden, dafi man ähnliche Erzeugnisse erhält, wenn man in Abänderung des zuletzt genannten Verfahrens die wasserlöslichen Kondensationsprodukte aus Formaldehyd und Harnstoff hier bei der Herstellung von Erzeugnissen aus Formaldehyd, anderen Carbonylverbindungen als Aldehyden und Ammoniumsalzen mitverwendet.It has now been found that similar products are obtained if in a modification of the last-mentioned process, the water-soluble condensation products from formaldehyde and urea here in the manufacture of products from formaldehyde, others Carbonyl compounds used as aldehydes and ammonium salts.

Man kann die wasserlöslichen Kondensationsprodukte aus Formaldehyd und Harnstoff während der Umsetzung zugeben oder mit ihnen die aus Formaldehyd, anderen Carbonylverbindungen alsAldehyden und Ämmoniumsalzen erhaltenen Erzeugnisse noch nachbehandeln.One can use the water-soluble condensation products from formaldehyde and add urea during the reaction or with them the formaldehyde, carbonyl compounds other than aldehydes and ammonium salts still treat afterwards.

Die so erhältlichen farbhellen, haltbaren und temperaturbeständigen Erzeugnisse können für die Papierleimung oder für das Fixieren von Gerbstoffen verwendet werden. Beispiel i Man löst 6o Teile Harnstoff in 6oo Teilen 3o°/oigem wäßrigem Formaldehyd, dessen pH-Wert 8,1 beträgt, und läßt die erhaltene Lösung etwa 15 Stunden lang stehen. Dann gibt man 116 Teile Aceton und 264 Teile Ammoniumsulfat zu und läßt das Gemisch weitere 48 Stunden bei Zimmertemperatur stehen. Man erhält eine Lösung, die als solche zum Fixieren von Farb-und Gerbstoffen dienen kann. Man kann auch durch Eindampfen daraus einen festen Stoff gewinnen, der sich in Wasser klar zu fixierend wirkenden Lösungen auflöst.The brightly colored, durable and temperature-resistant ones available in this way Products can be used for paper sizing or for fixing tanning agents will. EXAMPLE i 60 parts of urea are dissolved in 600 parts of 30% aqueous Formaldehyde, the pH of which is 8.1, and leaves the resulting solution for about 15 hours stand long. Then 116 parts of acetone and 264 parts of ammonium sulfate are added and let the mixture stand for a further 48 hours at room temperature. You get one Solution that can be used as such to fix dyes and tannins. One can A solid substance can also be obtained from it by evaporation, which becomes clear in water dissolves solutions that have a fixing effect.

Beispiel e In einem Gemisch von 6oo Teilen 3o°/oigem wäßrigem Formaldehyd und 116 Teilen Aceton löst man in der Kälte ein Gemisch von 264 Teilen Ammoniumsulfat und 6o Teilen Harnstoff. Man läßt die Lösung 3 Tage bei Zimmertemperatur stehen. Das erhaltene Produkt hat ähnliche Eigenschaften wie das nach Beispiel i erhaltene.Example e In a mixture of 600 parts of 30% aqueous formaldehyde and 116 parts of acetone, a mixture of 264 parts of ammonium sulfate is dissolved in the cold and 60 parts of urea. The solution is left to stand for 3 days at room temperature. The product obtained has similar properties to that obtained according to Example i.

Beispiel 3 Ein Gemisch aus 6o Teilen Harnstoff und Zoo Teilen einer 3o°;oigen wäßrigen Formaldehydlösung, deren pH-Wert 8,o beträgt, wird 3o Minuten lang auf 4o bis 45' erhitzt. In die erhaltene Lösung läßt man ein Gemisch aus 4oo Teilen einer 3o°/oigen wäßrigen Formaldehydlösung, 147 Teilen Cyclohexanon und 252 Teilen Ammoniumsulfat einlaufen und erwärmt das Ganze unter Rühren 6o Minuten lang auf 5o bis 6o'. Man erhält eine gelbgefärbte, klare Lösung, die sich sehr gut zum Fixieren von Gerbstoffen eignet.Example 3 A mixture of 60 parts of urea and zoo parts of one 30% aqueous formaldehyde solution, the pH of which is 8.0, is 30 minutes Heated for a long time from 40 to 45 '. A mixture of 4oo is allowed into the resulting solution Parts of a 30% aqueous formaldehyde solution, 147 parts of cyclohexanone and 252 parts Pour in parts of ammonium sulfate and heat the whole thing while stirring for 60 minutes on 5o to 6o '. A yellow-colored, clear solution is obtained, which is very good for Fixing of tannins is suitable.
