Epichlorohydrin
Alias: epichlorohydrin; 3-chloro-1,2-epoxypropane; 1-chloro-2,3-epoxypropane; ECH; (±)-Epichlorohydrin
Uses :
Epichlorohydrin is used in the preparation of glycerol and glycidyl derivatives, epoxy resin and its epoxy reactive diluent and oxygen curing agent diluent, chlorohydrin rubber, neoprene rubber, flame retardant unsaturated resin, ion exchange resin, cellulose ester It is an important raw material for organic solvents such as cellulose ether, polyether polyol, etc. It is widely used in the production of epoxy resin, nitroglycerin explosives, glass fiber reinforced plastic, glycerol methacrylate, chlorohydrin rubber, glycidol derivatives, surfactants, water quality Coagulants, wood preservatives, paper-based reinforcing agents, chemical stabilizers, electroplating solutions, electrical insulation products, etc. These fine chemical products are widely used in chemical industry, light industry, transportation, medicine, paint, food, electronic appliances and other industries.
The epoxy resin prepared from Epichlorohydrin has the characteristics of strong adhesion, chemical resistance, good chemical stability, high impact strength and excellent dielectric properties. It is widely used in coatings, adhesives, reinforcing materials, casting materials and electronics. Laminates and other industries have a wide range of applications.
Packaging and storage :
airtight packaging, and store in a dry, cool and ventilated place, away from fire, heat sources, and prevent direct sunlight;
do not stack it with acids, alkalis and corrosive materials, moisture-proof, heat-proof, fire-proof, anti-corrosion;
and oxidants , Separate storage and transportation of edible chemicals.

Physicochemical properties:
Epichlorohydrin is colorless and transparent liquid with chloroform-like odor, volatile, unstable and flammable. It is miscible with most organic solvents such as ethanol, ether, chloroform, trichloroethylene and carbon tetrachloride. It is insoluble in water and cannot be miscible with petroleum hydrocarbons. It is toxic, and the maximum allowable concentration in the air is 5×10-6.
Use protection :
Respiratory protection: When the concentration in the air exceeds the standard, wear a mask-type respirator; in emergency rescue or evacuation, it is recommended to wear a self-contained breathing apparatus.
Eye Protection: Wear chemical safety goggles.
Protective Clothing: Wear tight-sleeved work clothes and long rubber shoes;
Hand Protection: Wear chemical resistant gloves.
Others: After work, shower and change; maintain good hygiene; prevent damage to skin and mucous membranes.
Fire fighting :
should use anti-solvent foam, carbon dioxide, dry powder, sand.
