Summary
A sensitive and convenient test is proposed for benzoate, in which the anion gives a colour reaction with lanthanum nitrate in the presence of iodine and ammonia. Benzoate has been identified in the presence of salicylate by thin-layer chromatography.
Zusammenfassung
Ein empfindlicher und brauchbarer Nachweis von Benzoat wurde vorgeschlagen, dem eine Farbreaktion mit Lanthannitrat in Gegenwart von Jod und Ammoniak zugrundeliegt. In Gegenwart von Salicylat wird Benzoat dünnschichtchromatographisch identifiziert.
