Description
Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie. Es wurde gefunden, dass man ein neues Zwischenprodukt der Teerfarbenindustrie er hält, wenn man Resorcin mit Dimethylolharn- stoff kondensiert. Das erhaltene Reaktions produkt stellt wahrscheinlich den (2, 2', 4, 4'-Tetraoxydibenzyl)harnstoff dar. Er ist ein weisses Pulver, welches 1 Mol Kristallwas ser enthält. Durch Trocknen auf 100 ver liert es das Kristallwasser und ist dann in Alkohol und Aceton unlöslich, wenn nicht etwas Wasser zugesetzt wird. Es löst sich in verdünnten Alkalien und wird aus dieser Lösung durch Säuren wieder gefällt. Die Sub stanz zersetzt sich ohne zu schmelzen bei 134-140 .
Beispiel: 8 Teile Resorcin und 5 Teile Dimethyl- olharnstoff werden in 120 Teilen Wasser ge löst. Zu dieser auf 0 abgekühlten Lösung werden langsam 35 Teile konzentrierter Salzsäure eingetropft. Die eintretende weisse Fällung wird sofort durch Filtrieren von der Lauge getrennt, in kaltem Alkohol gelöst und aus dieser filtrierten Lösung durch Zu satz von Wasser wieder gefällt. Zur Reini gung kann das Produkt in wasserhaltigem Aceton gelöst und nach dem Filtrieren durch Eindampfen im Vakuum wieder gewonnen werden.
Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate product in the tar color industry is obtained when resorcinol is condensed with dimethylolurea. The reaction product obtained is probably the (2, 2 ', 4, 4'-tetraoxydibenzyl) urea. It is a white powder which contains 1 mol of crystal water. By drying to 100 it loses the water of crystallization and is then insoluble in alcohol and acetone unless a little water is added. It dissolves in dilute alkalis and is precipitated from this solution by acids. The substance decomposes without melting at 134-140.
Example: 8 parts of resorcinol and 5 parts of dimethyl olurea are dissolved in 120 parts of water. 35 parts of concentrated hydrochloric acid are slowly added dropwise to this solution, which has cooled to 0. The white precipitate that occurs is immediately separated from the lye by filtration, dissolved in cold alcohol and precipitated from this filtered solution by adding water. For cleaning, the product can be dissolved in hydrous acetone and recovered after filtering by evaporation in vacuo.
