2,3-Dichloro-1-propene(CAS: 78-88-6)

2,3-Dichloro-1-propene (CAS: 78-88-6) is a colorless to light yellow liquid at room temperature. Its molecular weight is approximately 124.03 g/mol. It has a low water solubility (0.36 g/100 mL at 20°C). This compound is highly reactive and prone to hydrolysis and oxidation. It is flammable and exhibits strong reactivity with nucleophiles.

2,3-Dichloro-1-propene is typically synthesized by the chlorination of propylene using chlorine gas. The reaction is highly exothermic and requires careful temperature control. Catalysts such as HCl or BF3 are often used to improve selectivity and yield. The process yields 2,3-dichloropropene as a primary product with minor by-products.

2,3-Dichloro-1-propene is used in the pharmaceutical industry for intermediates and agricultural chemicals. It is also used in the polymer industry for the synthesis of certain polymerization initiators. Additionally, it is employed in the production of sensors and in semiconductor manufacturing for cleaning and etching processes.

When handling 2,3-Dichloro-1-propene (CAS: 78-88-6), it is essential to use personal protective equipment (PPE) such as gloves, goggles, and a respirator. It should be stored in a well-ventilated area and handled in a fume hood. Spills should be cleaned up using appropriate absorbent materials, and the area should be properly ventilated. Safety data sheets (SDS) should be consulted for detailed information on safe handling and disposal.
