At 20 0C, 2,4,6-trichlorophenol is a solid with very low volatility and moderate
solubility. Once it is dissolved, it is volatilizes slowly and adsorbs moderately to organic matter.
When present in the soil, it dissolves at a moderate rate. Once dissolved, 2,4,6-trichlorophenol can
reach the groundwater table or flow into a waterway, where it will be diluted before slowly
volatilizing. Fragments of 2,4,6-trichlorophenol can also be carried into waterways where they will
be deposited at the bottom and dissolve. Once the source has been removed, the adsorbed phase will
take a while to disappear, slowly liberating contamination in either the gaseous or dissolved state.
The resulting dissolved plume will be relatively large in size while the gaseous plume will
be generally small in size.
2,4,6-trichlorophenol should be handled with care, as it is toxic.
2,4,6-trichlorophenol has been used as an intermediate in the production of higher
chlorinated phenols, especially 2,3,4,6-tetrachlorophenol and pentachlorophenol.
2,4,6-trichlorophenol has also been used as a wood preservative, fungicides, bactericides,
germicides and as an anti-mildew agent in leathers, glues and textiles.
The use of 2,4,6-trichlorophenol has been decreasing as the fabrication processes produces
dioxins and furans.
