Zusammenfassung

Das Antioxydans 6-Äthoxy-2,2,4-trimethyl-1,2-dihydrochinolin (I) enthält als Beimengungen p-Phenetidin und 6-Äthoxy-2,4-dimethylchinolin (II). p-Phenetidin kann neben I und II mittels 2,4-Dinitrofluorbenzol nachgewiesen werden. I gibt mit Natriumnitrit in saurem Medium eine Farbreaktion; damit kann es nachgewiesen werden. Dabei setzen sich p-Phenetidin und II nicht um. Außerdem kann I neben p-Phenetidin und II mit Chloramin T nachgewiesen werden.

Summary

The antioxidant 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline (I) contains as admixturesp-phenetidine and 6-ethoxy-2,4-dimethylquinoline (II).p-Phenetidine can be detected in the presence of (I) and (I) by means of 2,4-dinitrofluorobenzene. (I) yields a color reaction with sodium nitrite in acid medium; hence it may be detected.p-Pheneteidine and (II) give no response. Furthermore (I) may be detected in the oresence ofp-phenetidine and (II) by means of chloramine T.
