1,4-dichlorobenzene is an important organic compound with the following uses and functions:
Main purpose
1. Insect and mold prevention: As a fumigation insecticide, it is used to control storage pests and prevent fabric damage. Used for manufacturing insect proof sanitary balls to protect clothing, wool, and other materials from pests.
2. Disinfection and air purification: It has strong adsorption and conversion effects on ammonia and amine substances, and is suitable for disinfection, deodorization, and air purification in public places such as toilets, parking lots, and theaters.
3. Chemical synthesis: As a dye intermediate, it is used to synthesize dyes such as bright red based GG and reactive light yellow. Used for synthesizing pesticide intermediates (such as dicamba) and pharmaceutical intermediates. As an organic synthesis raw material, it participates in the preparation of special materials such as polyphenylene sulfide (PPS resin).
4. Other industrial applications: A small amount is used in industrial fields such as special pressure lubricants and corrosion inhibitors. As a biochemical reagent, it is used for the preparation of plant cell chromosome specimens.
Functional characteristics
1. Physical characteristics: Easy to sublimate, can achieve continuous insect and deodorizing effects through volatilization.
2. Chemical properties: Flammable, soluble in organic solvents such as ethanol and ether, insoluble in water.
3. Safety: When used as an anti mold and anti moth agent at low concentrations, it is a low toxicity product, but high concentrations or long-term exposure may cause harm to the human body.
