Abstract:

2,4,6-Trichloroaniline 2,4,6-TCA is not a contaminant of the estuarine sediments of the Edgewood Arsenal area of the Aberdeen Proving Ground APG, MD. This conclusion was reached through a study of the environmental fate of 2,4,6-TCA and by direct analysis of sediment samples. 2,4,6-TCA is soluble in water mgL to the extent of 32 mgL at 19C, and is degraded by sunlight. The compound is also lost rapidly by evaporation from water. Analysis of sediments by gas chromatographymass spectrometry showed two major substances 2,4,6-trichloroaniline and 2,4,6-trichlorophenylisocyanate, in nearly equal concentrations. It was found that these substances arise by pyrolysis of N,N-bis2,4,6-trichlorophenyl urea. This occurs when the urea is injected into the hot 250 C injection port of the gas chromatography. The presence of N,N-bis2,4,6-trichlorophenyl urea was also confirmed by high pressure liquid chromatography.
