Product Description

1.Introduction
Para-chlorophenol, also known as p-chlorophenol (English name), 4-chloro phenol (4-chloro), 4-chloro-1-hydroxybenzene (4-chloro-1-hydroxybenzene), p-chloro-1-hydroxy benzene (4-chloro-1-hydroxybenzene), and 4-chloro-1-hydroxybenzene (4-chloro-1-hydroxybenzene). Pure products are colorless crystals, industrial products are yellow or pink crystals or powder. Volatile, steam has an unpleasant irritating odor. Flammable, slightly soluble in water, solubility in water (20ºC) 27.1g/L, soluble in benzene, ethanol, ethyl ether, glycerol, chloroform, fixed oil and volatile oil. 1% aqueous solution makes litmus acidic, its acidity is less than phenol, stronger than benzene. This product is mainly used in pesticide, medicine, dyestuff, plastic and other industries, also used as ethanol color changing agent, selective solvent for refining mineral oil, microscopic analysis, etc. When p-chlorophenol meets open fire and high heat, it can be flammable and decomposes at high temperature to produce toxic and corrosive flue gas.

3.Application:
Para-chlorophenol is mainly used in pesticide, medicine, dyestuff, plastic and other industries, and also used as denaturing agent for alcohol and selective solvent for refining mineral oil. Can also be used for microscopic analysis, plant growth promoter.

 

Used for the synthesis of dyes, and dilute nitric acid reaction to produce a, dinitroxide are dye intermediates; A variety of dyes can be further synthesized, such as neutral brilliant green BL, etc. In the pesticide industry, it is mainly used for the synthesis of fenruning, imidazone, wool fungicide, anti-lancin (multi-functional plant growth regulator), propanophos (endogenous insecticide), tamphorus, insecticide, mite egg ester (non-endogenous acaricidal agent), acaricidal ester, acaricidal ether; In the pharmaceutical industry for carboxylation of 5-chloro-2-hydroxy-benzoate sodium, synthesis of Antoamine, p-chlorophenoxy isobutyric acid and other drugs; It is also used in the synthesis of antioxidant BHA (butylated hydroxyanisole), etc.
