Blog Chlorine Products Epoxy chloropropane (ECH)
As an important organic chemical material and fine chemical product, epichlorohydrin (EPI) has a wide range of applications. The epoxy resin, produced with EPI as the raw material, is characterized by strong bonding, chemical mediator corrosion resistance, good chemical stability, high impact strength, outstanding electrical performance of mediators, etc.
Epoxy chloropropane, a vital compound in the family of chlorine downstream products, holds significant importance in various industrial applications. At REWINZ, we take pride in offering a complete production line for Epoxy chloropropane, empowering industries with a reliable solution for their chemical synthesis needs. Join us as we explore the multifaceted world of Epoxy chloropropane and uncover its diverse applications across different sectors.
Chemical Composition:
Epoxy chloropropane, with the chemical formula C₃H₅OCl, is a colorless liquid with a distinctive odor. This compound features an epoxy group and a chlorine atom, making it a versatile building block in chemical synthesis.
There are two EPI production methods, i.e. propylene chlorination process at elevated temperatures and allyl acetate process.
The first method involves use of propylene as raw material and chlorination of propylene at elevated temperatures to generate 3-allyl chloride to react with hypochlorous acid so as to produce dichlorohydrin, and then addition of alkali (caustic soda or lime milk) to cyclize dichlorohydrin to produce epichlorohydrin.
The second method involves oxidation of propylene in the presence of catalyst and acetic acid to generate allyl acetate, hydrolysis of allyl acetate to produce allyl alcohol, chlorination of allyl alcohol to produce dichlorohydrin, saponification of dichlorohydrin to produce epichlorohydrin, and then distillation, separation and removal of heavy components to produce the epichlorohydrin.
| Raw material | Domestic technology | Introduced technology | Allyl acetate |
|---|---|---|---|
| Propylene (95%) | 1000～1100 | 720 | 620 |
| Chlorine gas (99%) | 1600 | 2200 | 920 |
| Sodium carbonate (95%) | 800～1000 | – | – |
| Caustic soda (42%) | 700～1000 | 1130 (Slaked lime) | – |
| Oxygen | – | – | 276(m3) |
As an important organic chemical material and fine chemical product, epichlorohydrin (EPI) has a wide range of applications. The epoxy resin, produced with EPI as the raw material, is characterized by strong bonding, chemical mediator corrosion resistance, good chemical stability, high impact strength, outstanding electrical performance of mediators, etc., and is widely applied in the fields of coatings, adhesives, reinforced materials, casting materials, electronic shell products, etc. At present, the industrial EPI production methods mainly refer to the propylene chlorination process at elevated temperatures and allyl acetate process.
Health Precautions: Due to its hazardous nature, proper safety measures must be followed when handling Epoxy chloropropane to prevent exposure and ensure the well-being of workers.
