General description

2,4,5-Trichlorophenol (2,4,5-TCP) is employed as a raw material in the preparation of various biocides.

Application

2,4,5-trichlorophenol can be used as a starting material to synthesize:
  • Hexachlorophene, a fungicide, by the reaction with formaldehyde in the presence of concentrated H2SO4.
  • 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), a herbicide.
  • N-Benzyl-2-(2,4,5-trichlorophenoxy)acetamide, which is used as an intermediate to prepare 4-benzyl-6,7-dichloro-2H-benzo[b][1,4]oxazin-3(4H)-one via Smiles rearrangement.

The product has been used to study its sorption onto montmorillonite based sorbents.

Intimate coupling of photocatalysis and biodegradation (ICPB) offers potential for degrading biorecalcitrant and toxic organic compounds. This study reports on a novel sponge-type, TiO(2)-coated biofilm carrier that showed significant adherence of TiO(2) and ability to accumulate biomass in its interior.
