Description
verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie. Es wurde gefunden, dass man ein neues Zwischenprodukt der Teerfarbenindustrie er hält, wenn man die 1-Oxy-2-naphthoesäure mit Dimethylolharnstoff kondensiert. Das er haltene Reaktionsprodukt stellt wabrschein- lich den symmetrischen Di[methyl(1)oxy(4)- carboxy(3)naphthaliir]harnstoff dar. Er ist ein weisses Pulver, welches in den üblichen or ganischen Lösungsmitteln äusserst wenig lös lich ist. Er schmilzt bei 2021' unter Zer setzung.
<I>Beispiel:</I> 20 Teile 1-Naphthol-2-carboiisäure und 7 Teile Dimethylollrarristoff werden in 300 Teilen 60%igem Alkohol gelöst und die Lö sung in der Kälte mit Salzsäuregas gesättigt, Das ausgeschiedene Reaktionsprodukt wird nach längerem Stehen von der Lauge abfil- triert, mit verdünntem Alkohol gewaschen, in Soda gelöst und aus dieser Lösung durch Zusatz von Mineralsäure wieder gefällt.
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 paint industry is obtained by condensing 1-oxy-2-naphthoic acid with dimethylolurea. The reaction product obtained is probably the symmetrical di [methyl (1) oxy (4) - carboxy (3) naphthalene] urea. It is a white powder which is extremely sparingly soluble in common organic solvents. It melts with decomposition at 2021 '.
<I> Example: </I> 20 parts of 1-naphthol-2-carboiic acid and 7 parts of dimethylol mineral are dissolved in 300 parts of 60% alcohol and the solution is saturated with hydrochloric acid gas in the cold the lye is filtered off, washed with dilute alcohol, dissolved in soda and precipitated again from this solution by adding mineral acid.
