The main purpose:
P-Chlorophenol is mainly used in pesticides, medicine, dyes, plastics and other industries. It is also used as a denaturant for alcohol and a selective solvent for refined mineral oil. It can also be used for microscope analysis and plant growth promoter.
It is used to synthesize dyes, reacting with dilute nitric acid to generate mono- and dinitro compounds are dye intermediates; it can further synthesize a variety of dyes, such as neutral brilliant green BL. In the pesticide industry, it is mainly used to synthesize Fenpyrin, Mimidone, Fleece Fungicide, Antifox (Multifunctional Plant Growth Regulator), Profenofos (Systemic Pesticide), Tetraphos, Insecticide, Difenophos (non-systemic acaricide), dicofenate, dicofen; used in the pharmaceutical industry to carboxylate sodium 5-chloro-2-hydroxybenzoate, synthesize antomin and p-chlorophenoxy isobutyl Acid and other drugs; it is also used to synthesize antioxidant BHA (butylated hydroxyanisole) and so on.
Packaging, storage and transportation
P-Chlorophenol is packaged in an iron drum lined with plastic film or kraft paper, and placed in a dry, ventilated and cool place. Keep away from fire sources, and avoid mixed shipment with iron salts, heavy metal salts, potassium permanganate, hydrogen peroxide, iodine, bromine, protein, collodion, etc.
Pure p-chlorophenol is white crystal, industrial product is yellow or pink crystal, almost insoluble in water, soluble in benzene, ethanol, ether, glycerol, chloroform, fixed oil and volatile oil. This product is mainly used for microscopic analysis, pharmaceutical and dye intermediates, alcohol denaturant and solvent, etc. it is also used as selective solvent for refining mineral oil. In the agricultural industry, it is mainly used for the synthesis of Triadimefon, Verbenone, wool fungicide, clozapine, propafenone, tetraphos, insecticide, etc. it is also used for the manufacture of pesticide fungicide 5,5 'dichloro-2,2' dihydroxydiphenylmethane and plant growth promoter. Dyestuff industry is used to produce 1,4-Dihydroxyanthraquinone, 1,4-diaminoanthraquinone, p-aminophenol and hydroquinone. The pharmaceutical industry is used for carboxylation of sodium 5-chloro-2-hydroxybenzoate, synthesis of p-chlorophenoxyisobutyric acid and other drugs, and synthesis of antioxidant BHA (butyl hydroxyanisole).
