FAQ

What are the physical and chemical properties of 1,1,2-Trichloroethane (CAS: 79-00-5)?

1,1,2-Trichloroethane (CAS: 79-00-5) is a colorless, slightly toxic liquid with a chloroform-like odor. It has a molecular weight of 133.40 g/mol and a boiling point of 88.9 °C. It is soluble in water (2.5 g/L at 20 °C) and miscible with most organic solvents. It is not highly reactive under normal conditions but can react with strong bases to form chloroform and ethylene.

How is 1,1,2-Trichloroethane (CAS: 79-00-5) typically synthesized?

1,1,2-Trichloroethane is typically synthesized via the addition of chlorine to propylene in the presence of a Lewis acid catalyst, such as aluminum chloride. The reaction is selective and yields 1,1,2-Trichloroethane with high purity and good yield. The process is carried out under anhydrous conditions to prevent hydrolysis.

What industries use 1,1,2-Trichloroethane (CAS: 79-00-5)?

1,1,2-Trichloroethane (CAS: 79-00-5) is used in various industries, including pharmaceuticals for extraction and purification processes, polymers as a blowing agent, and in the production of chlorinated solvents. It is also utilized in the electronics industry for cleaning and as a carrier solvent.

What precautions should be taken when handling 1,1,2-Trichloroethane (CAS: 79-00-5)?

When handling 1,1,2-Trichloroethane (CAS: 79-00-5), appropriate personal protective equipment (PPE) is essential, including gloves, goggles, and a respirator. It should be stored in a cool, well-ventilated area away from heat sources and incompatible materials. Fume hoods should be used during use to minimize inhalation risks. In case of spills, they should be cleaned up with appropriate disposal procedures as outlined in the SDS (Safety Data Sheet).
