1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

2. CHEMICAL STRUCTURE
2.1. Molecular Structure
Tellurium chloride is an inorganic compound of tellurium and chlorine. Tellurium ions (Te⁴⁺) and chloride ions (Cl⁻) are present in a 1:4 ratio. It has a molecular structure and appears as a white to pale yellow crystalline solid under ambient conditions. It hydrolyzes in water to form tellurium dioxide (TeO₂) and hydrogen chloride (HCl). It is soluble in organic solvents. It is unstable in humid environments.

18. CRITICAL WARNINGS AND BEST PRACTICES

CRITICAL WARNINGS:

• Highly Toxic: Tellurium chloride is fatal if swallowed or inhaled (H300, H330). Exposure must be strictly minimized.

• Corrosive: Causes severe skin burns and eye damage (H314). Protective equipment is mandatory.

• Hygroscopic and Moisture Sensitive: Rapidly absorbs moisture and hydrolyzes, releasing toxic hydrogen chloride (HCl) gas. Extreme care must be taken to avoid moisture during storage and handling.

• Environmental Hazard: Very toxic to aquatic life (H400/H410). Release into water sources must be strictly prevented.

• Thermal Decomposition: Decomposes at ~380°C releasing toxic chlorine gas (Cl₂). Ventilation is essential.

BEST PRACTICE RECOMMENDATIONS:

• Storage:

  • Store in a cool, dry, and well-ventilated area.

  • Use moisture-proof, airtight containers.

  • Keep away from water and moisture.

  • Store at room temperature (15-25°C).

  • Store locked up.

• Handling:

  • Use in well-ventilated areas with local exhaust ventilation or under a fume hood.

  • Use a respirator, protective goggles, chemically resistant gloves, and protective clothing.

  • Avoid dust formation and inhalation.

  • Avoid contact with water and moisture.

  • Wash hands thoroughly after handling.

  • Remove contaminated clothing and wash before reuse.

• Waste Management:

  • Dispose of in accordance with local regulations at licensed disposal facilities.

  • Do not discharge into water sources.

  • For large quantities, tellurium recovery should be considered.
