1,1,2,2-tetrachloroethane

1,1,2,2-tetrachloroethane is a chlorinated organic solvent with the chemical formula C2H2Cl4 and CAS number 79-34-5. This synthetic chemical compound belongs to the family of chloroalkanes and has a molecular weight of 167.8 g/mol. It is classified as highly toxic with acute toxicity categories 1 and 2, making it extremely dangerous to human health. The substance also poses environmental risks, particularly to aquatic ecosystems with chronic toxicity effects.

1,1,2,2-tetrachloroethane is a colorless liquid at room temperature with a characteristic sweet, chloroform-like odor. It has a high density due to its chlorine content and is sparingly soluble in water but miscible with most organic solvents including alcohols and ethers. The compound is volatile and can easily evaporate at ambient conditions. Its high chlorine content makes it chemically stable under normal conditions but potentially reactive under certain circumstances.

1,1,2,2-tetrachloroethane is primarily used as an industrial solvent and chemical intermediate in specialized applications. It serves as a solvent for resins, waxes, and other organic materials in industrial processes. The compound is also utilized as an intermediate in the synthesis of other chlorinated compounds and in certain analytical chemistry applications. Due to its high toxicity classification, its use is heavily restricted and limited to professional industrial applications with appropriate safety measures.

1,1,2,2-tetrachloroethane must be handled with extreme caution due to its Acute Tox. 1 and 2 classifications. Essential protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection in well-ventilated areas or fume hoods. Workers must wear appropriate protective clothing to prevent skin contact. All handling should occur in controlled environments with proper ventilation systems. Emergency procedures and safety data sheets must be readily available, and only trained personnel should work with this highly toxic substance.

1,1,2,2-tetrachloroethane must be stored in tightly sealed containers in cool, dry, well-ventilated areas away from heat sources and incompatible materials. Storage areas should be equipped with appropriate containment measures and maintained at stable temperatures. The substance should be kept away from strong oxidizing agents, alkali metals, and bases. Secondary containment is recommended to prevent environmental contamination. Access should be restricted to authorized personnel only, with proper labeling including GHS06 and GHS09 pictograms clearly visible.

Immediate action is crucial due to the substance's high toxicity. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. In case of eye contact, flush thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air immediately and provide artificial respiration if breathing has stopped. For ingestion, do not induce vomiting and seek emergency medical care immediately. Always contact poison control centers and provide safety data sheet information to medical personnel.

1,1,2,2-tetrachloroethane must be disposed of as hazardous waste through licensed waste management facilities due to its high toxicity and environmental classification. The substance cannot be disposed of in regular waste streams or sewerage systems. Disposal must comply with local, national, and EU waste regulations including the Waste Framework Directive. Professional waste contractors specializing in toxic chemicals should handle collection and treatment. Documentation and waste tracking certificates are required for proper regulatory compliance and environmental protection.

1,1,2,2-tetrachloroethane is classified under ADR Class 6.1 (toxic substances) Packing Group II, indicating high transport risk. Transportation requires appropriate UN-specification packaging, proper labeling with toxic substance markings, and transport documents including safety data sheets. Vehicles must carry appropriate emergency equipment and drivers need ADR certification for dangerous goods. Segregation from incompatible materials is mandatory. Transport should follow the shortest reasonable routes with emergency response procedures readily available throughout the journey.

1,1,2,2-tetrachloroethane is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification obligations. While not currently listed as a Substance of Very High Concern (SVHC), its high toxicity classification triggers strict handling and use restrictions. The substance falls under workplace safety regulations requiring specialized training and control measures. Industrial users must implement risk management measures and may face restrictions on certain applications. Regular monitoring and reporting obligations apply to commercial users and suppliers.

1,1,2,2-tetrachloroethane is available through specialized chemical distributors like OYSI, which supplies industrial chemicals across Europe. Due to its high toxicity classification and regulatory restrictions, procurement requires proper business credentials, safety certifications, and intended use declarations. Suppliers must verify customer qualifications and end-use applications before sales. Purchase typically involves minimum order quantities, specialized packaging, and compliance documentation.
