Allyl chloride is an important organic compound, which is widely used as a raw material for chemical production. This article will detail the properties and uses of allyl chloride.

1. properties of chloropropene

chloropropene is a colorless transparent liquid with a pungent odor. Its molecular formula is C3H5Cl, belonging to the halogenated hydrocarbon compounds. Chloropropene has high chemical activity and is prone to addition, substitution, polymerization and other reactions.

1. Physical properties
The boiling point of chloropropene is 49.9 ℃, the melting point is -136.4 ℃, the relative density is 0.9206(20/4 ℃), the refractive index is 1.4031, and the flash point is -17 ℃. Chloropropene insoluble in water, soluble in ethanol, ether and other organic solvents.

2. Chemical properties
allyl chloride has high chemical activity and is prone to addition, substitution, polymerization and other reactions. Common reactions include:
(1) Addition reaction: Chloropropene can react with hydrogen, halogen, water, etc.
(2) Substitution reaction: allyl chloride can be substituted with alcohols, phenols, amines and the like.
(3) polymerization reaction: allyl chloride can be polymerized to generate polyacrylate polymer compounds.

2. the use of allyl chloride

allyl chloride as an important organic compound, widely used as raw materials for chemical production, with the following purposes:

1. production of epoxy resin
allyl chloride can be with bisphenol A and other compounds polymerization reaction, the formation of epoxy resin. Epoxy resin has excellent chemical corrosion resistance, electrical insulation and mechanical properties, and is widely used in coatings, adhesives, electronic appliances, aerospace and other fields.

2. the production of acrylate monomer
allyl chloride can be esterified with alcohol compounds to produce acrylate monomer. Acrylic monomers are important raw materials for polymers, which can be used to produce acrylic resins, polyester resins and other polymer compounds, and are widely used in coatings, inks, adhesives and other fields.

3. Production of Chlorohydrins
Chloropropene can react with water to generate chlorohydrins. Chlorohydrin compounds are important raw materials for the production of pesticides and pharmaceutical intermediates, and can also be used in the production of plasticizers, solvents and other chemicals.

4. Production of other organic compounds
Chloropropene can also be used to produce other organic compounds, such as vinyl chloride, propionaldehyde, acetone, etc. These compounds are widely used in the fields of plastics, synthetic fibers, synthetic rubber, etc.

In conclusion, allyl chloride, as an important organic compound, has a wide range of uses. It can be used in the production of epoxy resin, acrylate monomer, chlorohydrin compounds and other organic compounds, providing an important raw material for the development of the chemical industry.
