What is 2-Iodopropane?
Chemical properties
Colorless liquid that discolors in air and light; miscible with chloroform, ether, alcohol and benzene; slightly soluble in water.
The Uses of 2-Iodopropane
Organic synthesis, pharmaceuticals. 2-Iodopropane (Isopropyl iodide) was used to prepare butyric and isobutyric acid.
The Uses of 2-Iodopropane
2-Iodopropane is used to prepare butyric and isobutyric acid, as a solvent, also used in medicine and organic synthesis.
Purification Methods
Treat the iodide with bromine, followed by extraction of free halogen with aqueous Na2S2O3 or NaHSO3, washing with water, drying (MgSO4 or CaCl2) and distilling. (The treatment with bromine is optional.) Other purification methods include passage through activated alumina, or shaking with copper powder or mercury to remove iodine, drying with P2O5 and distilling. Washing with conc H2SO4 or conc HCl (to remove any alcohol), water, aqueous Na2SO3, water and aqueous Na2CO3 has also been used. Treatment with silica gel causes some liberation of iodine. Distillations should be carried out at slightly reduced pressure. Purified isopropyl iodide is stored in the dark in the presence of a little mercury. [Beilstein 1 IV 223.]
