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.
