1,2-dichloroethene

1,2-dichloroethene is a halogenated organic compound with the chemical formula C2H2Cl2 and CAS number 540-59-0. This chlorinated hydrocarbon has a molecular weight of 96.94 g/mol and exists as two isomeric forms: cis and trans configurations. It is classified as a flammable liquid with acute toxicity properties and chronic aquatic toxicity. The substance carries the danger signal word and is represented by flame and exclamation mark GHS pictograms.

1,2-dichloroethene is a colorless liquid at room temperature with a characteristic sweet, chloroform-like odor. The substance has moderate volatility and limited water solubility, being more soluble in organic solvents. It exists in two geometric isomers with slightly different physical properties. The compound is lighter than water and exhibits flammable characteristics, requiring careful handling due to its vapor formation and potential for ignition under appropriate conditions.

1,2-dichloroethene is primarily used as an intermediate in chemical synthesis and as a solvent in various industrial applications. It serves as a precursor for producing other chlorinated compounds and specialty chemicals. The substance finds application in the manufacture of polymers, adhesives, and certain pharmaceutical intermediates. Due to its solvent properties, it may be used in extraction processes and specialized cleaning applications in controlled industrial environments.

1,2-dichloroethene requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection when necessary. Work should be conducted in well-ventilated areas or under fume extraction systems to prevent vapor accumulation. Avoid contact with skin, eyes, and inhalation of vapors. Keep away from heat sources, sparks, and open flames due to its flammable nature. Ensure proper grounding and bonding during transfer operations.

1,2-dichloroethene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Storage areas must be equipped with appropriate fire suppression systems and spill containment measures. Keep containers upright and protected from physical damage. Store separately from strong oxidizing agents, strong bases, and incompatible materials. Maintain storage temperatures within recommended ranges and ensure adequate ventilation to prevent vapor accumulation.

In case of skin contact with 1,2-dichloroethene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical help if breathing difficulties occur. In case of ingestion, do not induce vomiting and seek immediate medical assistance.

1,2-dichloroethene must be disposed of as hazardous waste according to local and national regulations. The substance cannot be disposed of in regular waste streams or sewerage systems due to its toxicity and environmental impact. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Incineration at approved high-temperature facilities or chemical treatment methods may be required. Always consult current waste management regulations and obtain proper waste classification codes before disposal.

1,2-dichloroethene is classified under ADR Class 3 (flammable liquids), Packing Group II, indicating moderate danger during transport. Packages must comply with UN packaging requirements and be properly labeled with appropriate hazard labels and markings. Vehicles must be equipped with appropriate fire extinguishing equipment and drivers must hold valid ADR certification. Transport documents must include proper shipping names, UN numbers, and emergency response information according to dangerous goods regulations.

1,2-dichloroethene is subject to REACH regulation requiring registration for manufacture or import above certain tonnages in the EU. The substance falls under CLP regulation for classification, labeling, and packaging requirements, mandating specific hazard communication. While not currently listed as an SVHC (Substance of Very High Concern), it may be subject to workplace exposure limits and environmental monitoring requirements. Users must comply with occupational health and safety regulations and environmental protection measures.
