Ethylene diiodide - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | for organic synthesis. |
| production method | results from the reaction of ethylene with iodine. Ethylene is passed into a mixture of iodine and ethanol until the color of the iodine is completely lost and needle-like crystals are produced. After completion of the reaction, filtration and washing were performed, and the obtained crude product was recrystallized from ethanol to obtain 1, 2-diiodoethane. |
