What Is Ethylene Dichloride?
Ethylene dichloride, known as dichloromethane or methylene chloride, is an organic compound formed through the radical reaction of methane or methyl chloride with chlorine. It’s the most stable methane chloride but susceptible to decomposition by light and oxygen over time, requiring careful storage.
Uses of Ethylene Dichloride
Valued for its flame-retardant properties and ability to dissolve numerous organic compounds, ethylene dichloride is utilized in various chemical reactions, metalworking industry as a cleaning agent, and in the production of polylactic acid and polyester polyol.
Properties of Ethylene Dichloride
This colorless liquid is known for its sweet aroma, high solubility in organic compounds, and immiscibility with water. With a melting point of -96.7°C and a boiling point of 40°C, it serves as an important solvent in organic chemistry.
Other Information on Ethylene Dichloride
1. Synthesis of Ethylene Dichloride
Produced industrially through the radical reaction of methane or chloromethane with chlorine, ethylene dichloride is one of several chlorinated methane derivatives obtained, necessitating purification by distillation.
2. Purification of Ethylene Dichloride
For use as a solvent, dehydration with molecular sieves or calcium hydride is recommended, avoiding sodium due to explosion risks.
3. Hazards of Ethylene Dichloride
Exposure can cause eye and skin irritation, anesthetic effects, central nervous system suppression, and liver dysfunction, with long-term exposure linked to bile duct cancer.
4. Restrictions on the Use of Ethylene Dichloride
Subject to reporting under safety laws, efforts are underway to limit its use in favor of environmentally friendly alternatives, with recycling and reuse practices being implemented.
