Description

Verfahren zur Darstellung eines Doppelsalzes aus Acridinoxalat und Oxalsäure Durch das Patent 553:281 ist ein Verfahren zur Darstellung von Salzen des Acridins mit Zitronen- oder Weinsäure geschützt. Es wurde nun gefunden, daß sich zu Vergällungszwecken, namentlich zur Vergällung fester Brennstoffe, die aus polymerisierten Aldehyden bestehen, auf Grund seines allgemeinen Verhaltens ganz besonders das übersaure Acridinoxalat eignet.Process for the preparation of a double salt from acridine oxalate and Oxalic acid by patent 553: 281 is a method for the preparation of salts of acridine protected with citric or tartaric acid. It has now been found that for denaturing purposes, in particular for denaturing solid fuels from polymerized aldehydes exist entirely due to their general behavior the acidic acridine oxalate is particularly suitable.

Die Darstellung dieses Doppelsalzes erfolgt durch Lösen von -1o Teilen Acridin und I4 Teilen kristallwasserhaltiger Oxalsäure in go Teilen Wasser unter Erwärmen. Aus der braunroten Lösung kristallisiert beim Erkalten das gelbe Doppelsalz in feinen filzigen Nadeln von der Zusammensetzung: C13H"N(COOH)., + (COOH)2 -- 2H20. Schmelzpunkt I62° unter Zersetzung. Für ein Salz der obigen Zusammensetzung berechnen sich 45,540/, Oxalsäure. Gefunden wurden 45,961/, Oxalsäure. Die mit dem Salz ausgeführte Wasserbestimmung ergab 8,970.10H20. Für die obige Formel berechnen sich g,12 °/" H20.This double salt is represented by loosening -1o parts Acridine and 14 parts of oxalic acid containing water of crystallization in 100 parts of water Heat. The yellow double salt crystallizes from the brown-red solution on cooling in fine felted needles of the composition: C13H "N (COOH)., + (COOH) 2 - 2H20. Melting point 162 ° with decomposition. Calculate for a salt of the above composition 45,540 /, oxalic acid. 45.961% oxalic acid was found. The one executed with the salt Water determination gave 8.970.10H20. The formula above gives g, 12 ° / " H20.
