Diiodomethane Usage And Synthesis
  • Chemical Propertieslight yellow or gold liquid with chloroform-like odour
  • UsesIn separating mixtures of minerals. In determining the specific gravity of minerals and other substances. In the manufacture of x-ray contrast media.
  • HazardMay be irritating and narcotic.
  • Purification MethodsFractionally distil it under reduced pressure, then fractionally crystallise it by partial freezing, and stabilize it with silver wool if necessary. It has also been purified by drying over CaCl2 and fractionally distilling from Cu powder. Store it in the dark. [Beilstein 1 IV 97.]
