1,2-dichloroethane

1,2-dichloroethane is an organochlorine compound with the chemical formula C2H4Cl2 and CAS number 107-06-2. This colorless liquid with a sweet, chloroform-like odor has a molecular weight of 98.96 g/mol. It is classified as a highly hazardous substance due to its flammable, carcinogenic, and toxic properties. The compound is widely used as an industrial solvent and chemical intermediate in various manufacturing processes.

1,2-dichloroethane is a colorless liquid at room temperature with a characteristic sweet, chloroform-like odor. It has a boiling point of 83.5°C and a density of 1.25 g/cm³. The compound is moderately soluble in water (8.6 g/L at 20°C) and miscible with most organic solvents including alcohols, ethers, and chlorinated solvents. It exhibits high volatility and forms flammable vapor-air mixtures.

1,2-dichloroethane is primarily used as an intermediate in the production of vinyl chloride monomer (VCM), which is essential for PVC manufacturing. It serves as a solvent for resins, asphalt, bitumen, rubber, and paint formulations. Additionally, it functions as a degreasing agent in metal cleaning operations, a component in adhesives and sealants, and an extraction solvent in pharmaceutical and chemical processing industries.

1,2-dichloroethane requires strict safety measures including use of chemical-resistant gloves, safety goggles, and respiratory protection in well-ventilated areas. Work should be conducted in fume hoods or with local exhaust ventilation to prevent vapor inhalation. Avoid contact with skin, eyes, and clothing. Keep away from heat sources, sparks, and open flames due to its flammable nature. Emergency shower and eyewash stations must be readily accessible.

1,2-dichloroethane must be stored in tightly sealed containers in cool, dry, well-ventilated areas away from heat sources and ignition points. Storage areas should be fireproof and equipped with appropriate fire suppression systems. Keep away from oxidizing agents, alkalis, and metals like aluminum and magnesium. Containers should be made of compatible materials such as stainless steel or glass, and storage temperatures should remain below 25°C.

Immediate skin contact requires thorough washing with soap and water for at least 15 minutes while removing contaminated clothing. For eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air immediately and provide oxygen if breathing is difficult. In case of ingestion, do not induce vomiting and seek immediate medical care. Always contact emergency services for significant exposures.

1,2-dichloroethane disposal must comply with local and European waste regulations as hazardous waste. It requires treatment at licensed hazardous waste facilities equipped for chlorinated solvent destruction, typically through high-temperature incineration or specialized chemical treatment. Never dispose of it in regular drains, soil, or municipal waste systems. Waste containers must be properly labeled and handled by certified waste management companies following ADR transport requirements.

1,2-dichloroethane is classified under ADR as Class 3 (flammable liquid), Packing Group II, requiring specialized transport containers and documentation. Vehicles must carry appropriate placards and emergency equipment. Drivers need ADR certification for dangerous goods transport. Packages must meet UN specification requirements and be properly labeled with hazard symbols. Transportation should follow designated routes and comply with tunnel restrictions and parking regulations for dangerous goods.

1,2-dichloroethane is subject to strict European regulations under REACH and CLP classifications as a Category 1B carcinogen. It requires authorization for certain uses and is restricted in consumer applications. Companies must maintain detailed safety data sheets, implement risk management measures, and report usage volumes. Workers require specialized training and health surveillance. The substance falls under occupational exposure limits and environmental discharge controls across EU member states.

1,2-dichloroethane is available through OYSI, a specialized European distributor of technical chemicals serving industrial customers across the continent. As a regulated substance requiring proper handling and documentation, it is only sold to qualified industrial users with appropriate licenses and safety infrastructure. OYSI provides comprehensive technical support, safety documentation, and ensures compliance with all European chemical regulations for professional applications.
