Description
Sättigt man das erhitzte Kresolsalz mit Kohlensäure statt im Druckgefäfs bei gewöhnlichem Druck, so erhält man eine geringere Ausbeute an Oxyuvitinsäure.If you saturate the heated cresol salt with carbonic acid instead of the ordinary in a pressure vessel Pressure, a lower yield of oxyuvitic acid is obtained.
Die Säure wird zur Herstellung von Farbstoffen benutzt.The acid is used to make dyes.
