GENERAL DESCRIPTION & APPLICATIONS
Pentachlorophenol (PCP), a moderately toxic compound, is a chlorinated hydrocarbon insecticide and fungicide. It is a colorless crystalline solid with a phenolic odor. It is available in blocks, flakes, granules, liquid concentrates, wettable powders, or solutions in petroleum. Color may vary from white to dark grayish brown depending on the purity of the compound. It is a disinfectant, a fungicide, and the most heavily used preservative for wood. It is primarily used to protect timber from fungal rot and wood-boring insects, but the technical material may also be extensively used in cooling towers of electric plants, as additives to adhesives based on starch and vegetable and animal protein, in shingles, brick walls, concrete blocks, insulation, pipe sealant compounds, photographic solutions, and textiles and in drilling mud in the petroleum industry

GENERAL DESCRIPTION OF CHLOROPHENOL COMPOUNDS
Chlorophenols  are organic halogen compounds of cyclic aromatics formed by replacing hydrogen atoms in phenol by 1-5 atoms of chlorine. There are 19 compounds of chlorophenols of three mono-, six isomeric substances each of di-, tri-, as well as three isomeric substances tetra-, and fully chlorinated pentachlorophenol.

Chlorinated phenol compounds are solids at room temperature, except 2-Monochlorophenol which melts at 8 C. They are toxic copounds. But the toxic property accounts for many of their uses. They are used as bactericides, fungicides and preservatives. The water solubility of chlorophenols is low. Most chlorophenols are commercially applied in the form of a chlorophenol-organic solvent formulation. The salt forms are useful in case of particularly tri- and tetrachlorophenols since salt forms are more soluble in water. Chlorinated phenols are weakly acidic, more acidic with more chlorinated. The octanol/water partition coefficients increases as chlorination increases. The taste and odour thresholds are quite low. Chlorophenols are prepared by the alkaline hydrolysis of the appropriate chlorobenzenes or by the direct stepwise chlorination reaction of phenol or lower chlorinated phenols at a high temperature. Genrally, higher chlorinated phenols and their salt forms are used in wood preservation industry and in surface treatments for fresh-cut logs and lumber against sapstain fungi and mould.  The lower chlorophenols serve as intermediates in the production of higher chlorophenols and various pesticides. 2-Chlorophenol is used for higher to 2,4-dichlorophenol, 2,4,6-trichlorophenol pentachlorophenol. 4-Chlorophenol is a starting material for making germicides such as 2-Benzyl-4-chlorophenol; it can also be converted to an analgesic of acetophenetidin. 2,4-Dichlorophenol with formaldehyde forms methylenebis compounds used as a mothproofing agent, an antiseptic, and a seed disinfectant. 2,4-Dichlorophenol, with chloroacetic acid, forms 2,4-Dichlorophenoxyacetic acid (2,4-D), used as a selective weed-killer, systemic herbicide and defoliant, also used to increase the latex output of old rubber trees and in fruit drop control. 2,4-Dichloropheno, with formaldehyde, forms methylenebis compounds used as a mothproofing agent, an antiseptic, and a seed disinfectant; 2,4-dichlorophenol, with chloroacetic acid, forms 2,4-Dichlorophenoxyacetic acid (2,4-D) used as a selective weed-killer, systemic herbicide and defoliant, also used to increase the latex output of old rubber trees and in fruit drop control. 2,4,6-Trichlorophenol is used as a bactericide and fungicide. The 2,4,5-isomer has similar applications and also can be converted into hexachlorophene or thiobis(trichlorophenol) used as germicides in soap; into dimethyl trichlorophenyl phosphorothioate, a systemic agent effective against grubs in cattle; into 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) or 2,4,5-Trichlorophenoxypropionic acid (2,4,5-TCPPA), both widely used as weed killers. Tetrachlorophenol is an insecticide and a bactericide and is used as a preservative for latex, wood, and leather. Pentachlorophenol is a disinfectant, a fungicide, and the most heavily used preservative for wood. It is primarily used to protect timber from fungal rot and wood-boring insects, but the technical material may also be extensively used in cooling towers of electric plants, as additives to adhesives based on starch and vegetable and animal protein, in shingles, brick walls, concrete blocks, insulation, pipe sealant compounds, photographic solutions, and textiles and in drilling mud in the petroleum industry.
