FAQ

What are the physical and chemical properties of 1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6)?

1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6) is a colorless, volatile liquid with a chlorofluorocarbon (CFC) odor. It has a molecular weight of 137.45 g/mol. This compound is sparingly soluble in water but soluble in most organic solvents. It is highly reactive with bases and can undergo hydrolysis and substitution reactions. It has a low boiling point of 39.5°C and a high vapor pressure, making it flammable and requiring caution in handling.

How is 1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6) typically synthesized?

1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6) is synthesized by the chlorination of difluoroethane. This process involves reacting difluoroethane with chlorine gas in the presence of a Lewis acid catalyst, such as aluminum chloride or iron chloride, to achieve high yields. The reaction is endothermic and requires careful temperature control to prevent decomposition and side reactions.

What industries use 1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6)?

1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6) has been used in various industries, including pharmaceuticals for drug solvents and intermediates, polymers as a blowing agent, and sensors as a reagent. It has also been applied in the semiconductor industry for cleaning and etching processes. However, due to its ozone-depleting potential, its use has been largely phased out in favor of more environmentally friendly alternatives.

What precautions should be taken when handling 1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6)?

When handling 1,1-Dichloro-1-fluoroethane (CAS: 1717-00-6), it is important to use appropriate personal protective equipment (PPE), including gloves, goggles, and a respirator. This compound should be stored in a cool, dry place, away from heat and ignition sources. It must be used in a well-ventilated area or a fume hood to minimize inhalation risk. Spills should be contained and handled according to the Material Safety Data Sheet (MSDS) guidelines. Always consult the latest SDS for detailed information.
