Beschreibung

Diiodomethane (CH2I2) is an iodine containing organic compound. Its decomposition in acetonitrile initiated by 310nm light has been investigated. Femtosecond pump-probe spectroscopic and ab initio molecular dynamics simulations studies of the photodecomposition of CH2I2 suggest the formation of the isomer of diiodomethane (CH2I-I) as hot photoproduct. In the atmosphere, it undergoes photolysis in the presence of ozone to afford iodine oxide (IO) which results in the formation of aerosols. Its vacuum ultraviolet (VUV) photoabsorption spectrum has been reported.
Diiodomethane
Diiodomethane has been used as a probe liquid for evaluation of the polar and dispersive components of the surface energy of the catecholamine coated fiber surfaces. It may be used for the preparation of cyclopropyl ketones, esters and amides.
Diiodomethane may be used as a probe solvent in contact angle measurement to analyze the hydrophilicity of polymer surfaces.

Chemische Eigenschaften

light yellow or gold liquid with chloroform-like odour

Verwenden

Diiodomethane is used to determine the density of minerals and other solid samples due to its high density. It is used as an optical contact liquid to determine the refractive index of certain gemstones. In simmons-smith reaction, it acts as a reagent to generate methylene (carbine) free radical. It reacts with olefins to prepare cyclopropanes with high stereo specificity.

Hazard

May be irritating and narcotic.
Diiodomethane has the advantages of high opacity,ease of penetration,and ease of removal because it evaporates fairly quickly.However,it can cause skin burns.

läuterung methode

Fractionally 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.]
