1,2-dichloroethane

1,2-dichloroethane is a chlorinated organic compound with the molecular formula C2H4Cl2 and CAS number 107-06-2. It is a colorless liquid with a sweet, chloroform-like odor and a molecular weight of 98.96 g/mol. This chemical is classified as a dangerous substance due to its flammable, carcinogenic, and toxic properties, requiring careful handling in industrial applications.

1,2-dichloroethane is a colorless, volatile liquid at room temperature with a characteristic sweet odor reminiscent of chloroform. It has moderate solubility in water and is miscible with most organic solvents. The compound has a boiling point of approximately 83°C and a density higher than water. Its volatility and chemical stability make it useful as a solvent and chemical intermediate.

1,2-dichloroethane is primarily used as an intermediate in the production of vinyl chloride monomer, which is essential for PVC plastic manufacturing. It also serves as a solvent for various industrial processes, including degreasing operations and as a component in some adhesives and paint removers. Additionally, it finds applications in the pharmaceutical and agrochemical industries as a chemical intermediate.

1,2-dichloroethane requires strict safety measures including wearing chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work must be conducted in well-ventilated areas or under fume hoods due to its toxic vapors and carcinogenic properties. Avoid ignition sources as it is flammable, and ensure emergency eyewash and shower facilities are readily accessible during handling operations.

1,2-dichloroethane must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Storage areas should be equipped with appropriate fire suppression systems and spill containment measures. Keep containers away from strong bases and oxidizing agents to prevent dangerous reactions, and ensure storage complies with local flammable liquid regulations.

1,2-dichloroethane contact requires immediate action: for skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical care, as the substance is toxic and carcinogenic.

1,2-dichloroethane disposal must comply with local and European waste regulations as it is classified as hazardous waste. The substance should be collected in appropriate containers and disposed of through licensed hazardous waste disposal facilities. Incineration at high temperatures in specialized facilities is typically required. Never pour down drains or dispose of with regular waste due to environmental and health risks.

1,2-dichloroethane is classified under ADR transport regulations as Class 3 (Flammable Liquids), Packing Group II. Transport requires appropriate UN-specification packaging, proper labeling with flammable liquid hazard labels, and compliance with ADR documentation requirements. Vehicles must carry appropriate emergency equipment, and drivers need ADR training certification for transporting this dangerous good across European borders.

1,2-dichloroethane is subject to extensive European regulations including REACH registration requirements and CLP classification as Carcinogenic 1B, Flammable Liquid 2, and Acute Toxic 4. It requires safety data sheets, appropriate hazard labeling with GHS pictograms (GHS02, GHS07, GHS08), and the danger signal word. Industrial users must comply with occupational exposure limits and environmental emission controls under various EU directives.
