Introduction
Diiodomethane. The following is an introduction to the properties, uses, preparation methods and safety information of diiodomethane:
Quality:
Appearance: Diiodomethane is a colorless to light yellow liquid with a special odor.
Density: The density is high, about 3.33 g/cm³.
Solubility: soluble in organic solvents such as alcohols and ethers, insoluble in water.
Stability: Relatively stable, but may be decomposed by heat.
Use:
Chemical research: Diiodomethane can be used as a reagent in the laboratory for organic synthesis reactions and the preparation of catalysts.
Disinfectant: Diiodomethane has bactericidal properties and can be used as a disinfectant in some specific situations.
Method:
Diiodomethane can generally be prepared by:
Reaction of methyl iodide with copper iodide: Methyl iodide is reacted with copper iodide to produce diiodomethane.
Methanol and iodine reaction: methanol is reacted with iodine, and the generated methyl iodide is reacted with copper iodide to obtain diiodomethane.
Safety Information:
Toxicity: Diiodomethane is irritating and damaging to the skin, eyes, and respiratory system, and may have effects on the central nervous system.
Protective measures: Wear protective glasses, gloves and gas masks when using to ensure a well-ventilated laboratory environment.
Storage and Handling: Store in a sealed, cool, well-ventilated place, away from fire and oxidants. Waste liquids should be disposed of in accordance with relevant environmental regulations.
