1,1,2-Trichloroethane(CAS: 25323-89-1)

1,1,2-Trichloroethane (CAS: 25323-89-1) is a colorless, volatile liquid with a chloroform-like odor. It has a molecular weight of 133.38 g/mol. This compound is moderately soluble in water but highly soluble in organic solvents. It is less reactive compared to other chlorinated hydrocarbons but can undergo substitution reactions under certain conditions. It has a melting point of -49.5°C and a boiling point of 89.2°C.

1,1,2-Trichloroethane (CAS: 25323-89-1) is synthesized via the chlorination of ethylene with chlorine gas in the presence of an excess of ethylene and a copper chloride catalyst. The process typically yields high selectivity and a yield of over 90%. The reaction is exothermic and requires careful temperature control to avoid decomposition.

1,1,2-Trichloroethane (CAS: 25323-89-1) is widely used in the pharmaceutical industry for the synthesis of certain drugs, particularly analgesics and antipyretics. It is also used in polymer production as a solvent and plasticizer. Additionally, it has applications in the electronics industry as a cleaning solvent for semiconductor fabrication and in the production of sensors for gas detection.

When handling 1,1,2-Trichloroethane (CAS: 25323-89-1), appropriate personal protective equipment (PPE) should be worn, including gloves, goggles, and a respirator. It should be stored in a cool, well-ventilated area away from heat sources and incompatible materials. Spills should be contained and cleaned up using appropriate absorbent materials. Eye and skin contact should be immediately rinsed with water, and medical attention should be sought if necessary. Always refer to the Safety Data Sheet (SDS) for detailed handling instructions and emergency procedures.
