Iodoethane is a chemical compound from the group of aliphatic , saturated halogenated hydrocarbons .
Extraction and presentation
Iodoethane can be prepared by reaction of ethanol with iodine in the presence of red phosphorus , or by addition of hydrogen iodide to ethene obtained.
properties
Iodoethane is a colorless, volatile, flammable liquid with an ethereal odor that is sparingly soluble in water. It has a dynamic viscosity of 0.556 mPa · s at 25 ° C. Upon contact with light, iodoethane turns red and slowly decomposes in water. The technical product contains silver , ethanol or copper as a stabilizer.
use
Iodoethane is used as a heavy liquid for mineral analysis and for organic synthesis.
safety instructions
The vapors of iodoethane can form explosive mixtures with air when the substance is heated above its flash point.
