| Toxicity | Pentachlorophenol (PCP) is very toxic to plants and are used as preharvest defoliants and general herbicides. Their use as herbicides is currently restricted to nonagricultural uses along drainage ditches, driveways, and fencerows. Commercial (technical) grades of PCP commonly contain manufacturing by- products, such as dioxin (HxCDD), which can be more toxic than the PCP itself. Another contaminant in PCP is HCB (Hexachlorobenzene). The use of PCP is being phased out because of the discovery of these highly toxic contaminants (9). PCP is a Restricted Use Pesticide (RUP). Restricted Use Pesticides may be purchased and used only by certified applicators. In 1988 the EPA announced further restrictions on the use of PCP as in the pulp and paper industry where it is used in paper coatings, sizing, adhesives and in inks. Registration for use in cooling towers and for certain oil well operations was also cancelled. The 1988 regulations also required compliance with dioxin (HxCDD) concentration limits in the final product. |

| Overview | pentachlorophenol (PCP) is white flake or crystalline solid in appearance, usually containing one molecule of crystal water, it is slightly hot and has a strong spicy smell. When it is dissolved in water, it generates corrosive hydrochloric acid gas; Industrial products are gray-black powder or flaky solid, melting point 187~189 ℃, boiling point about 309-310 ℃ (decomposition). Insoluble in water, solubility (20 ℃)20~25mg/L, soluble in most organic solvents such as ethanol, ether, benzene, slightly soluble in cold petroleum ether, but the solubility in carbon tetrachloride and paraffin is not large. It is acidic and has no corrosive effect on most metals in the absence of moisture. It reacts with sodium hydroxide to form white sodium salt crystals soluble in water. Incompatible with strong oxidants. Good stability, no ignition in air at 550 ℃. It is produced industrially from the direct chlorination of phenol in the presence of a catalyst or from hexachlorocytoses (α,β-isomers). Pentachlorophenol (PCP) is an important preservative, it can prevent the growth of fungi, inhibit bacterial corrosion, has long been used as leather and wood fungicides, it is effective for the control of mold and general insects (such as termites), and its sodium salt is used to eliminate the intermediate host of schistosomiasis, Oncomelania hupensis, and control the grass. Sensitive to fish and other aquatic animals, water content of 0.1-0.5ppm is lethal. Organic drugs, can be absorbed through the skin, the liver, kidney damage. Ingestion can lead to poisoning and death in severe cases. However, in the past decade, medical research has found that if you often contact with products containing pentachlorophenol (PCP), it is very likely to affect human health, and the symptoms include Head Pain, Abdominal Pain, vomit and the central nervous system damage. The German government has established legislation to limit the content of pentachlorophenol (PCP) to 5ppm, which applies to a variety of products that have been treated with PCP and PCP compounds, such as bags and wristbands. All products exported to the German market must pass the above tests. China's ecological textile standards and the international ecological textile association of the oeko-tex standard 100 of the PCP residues in textiles should not exceed 0.5mg/kg (infant products should not exceed 0.05mg/kg) limit. |
| Use | is used in organic synthesis, control of rice fields, and wood preservation. Is also widely used fungicide, sterilization effect is high, suitable for polyvinyl chloride and other plastics, coatings, leather, adhesives, rubber, fiber, paper, etc., the general dosage of 0.1-0.5%. It is also effective for the control of termites, snails and the like. use as jet engine fuel use as reference material for pesticide analysis |
| production method | sodium pentachlorophenol is prepared by high-pressure hydrolysis using hexaenoic acid as raw material and then acidified. |
