Nature:
-Appearance: Colorless to slightly yellow crystal
-Melting point: 84-86 ° C
-Boiling Point: 245-248 ° C
-Density: 2.10g/cm³
-Solubility: Soluble in organic solvents such as chloroform, carbon disulfide and ethanol
Use:
2,3-dichloroiodobenzene has important application value in organic synthesis, and is often used as catalyst or reaction raw material. It can be used to synthesize other organic compounds, such as organometallic compounds, drugs, pigments, etc.
Method:
The synthesis of 2,3-dichloroiodobenzene is usually obtained by reacting chlorobenzene iodide with cuprous iodide. First, chlorobenzene iodide is reacted with cuprous iodide in the presence of a catalyst to obtain 2,3-diiodobenzene. Next, a chlorination reaction is carried out with hydrogen chloride gas in the presence of cuprous chloride to produce 2,3-dichloroiodobenzene.
Safety Information:
-2,3-dichloroiodobenzene is an organic compound, and care should be taken to avoid direct contact with skin and eyes.
-Wear chemical gloves, goggles and protective clothing when using.
-During operation, avoid inhaling its vapor and ensure good ventilation.
-When storing, keep it in a sealed, dry, cool place, away from fire and oxidizing agents.
-When disposing of waste, it should be disposed of in accordance with relevant regulations.
