Acetone solution of the amino derivatives from three diphenyl ether herbicides, nitrofenamino (p-aminophenyl 2, 4-dichlorophenyl ether), chlornitrofen-amino (p-aminophenyl 2, 4, 6-trichlorophenyl ether), and chlomethoxynil-amino (4-amino-3-methoxyphenyl 2, 4-dichlorophenyl ether) shows two peaks on a gas chromatogram (equipped with FID or ECD), respectively. GC-mass spectrometry revealed that the first peak was the amino compound, and the second was the condensate with acetone. The condensates were N-isopropylidene-p-(2, 4-dichlorophenoxy) aniline, N-isopropylidene-p-(2, 4, 6-trichlorophenoxy) aniline, and N-isopropylidene-4-(2, 4-dichlorophenoxy)-2-methoxyaniline. Results of experiments in which acetone was replaced with hexane suggest that the amino compounds in acetone exist in free states, or form easily reversible combinations with acetone and the dehydrated condensates are formed at the injection port (230℃) immediately after injecting the solution into GC.
