제조 방법

Beryllium iodide has the formula BeI2. It is very hygroscopic and reacts violently with water, forming hydroiodic acid. Beryllium iodide can be prepared by reacting Be metal with elemental iodine at temperatures of 500°C–700°C:
Be＋I2→BeI2
Beryllium iodide is also formed when beryllium carbide reacts with hydrogen iodide in the gas phase:
Be2C＋4HI→2BeI2＋CH4
Beryllium Iodide, BeI2, was first prepared by W?hler (1828) and Debray (1855) who prepared the iodide by the action of iodine upon the metal. Lebeau (1898), was the first to prepare large quantities (for the time) by the action of gaseous hydroiodic acid, or a mixture of hydrogen and iodine vapor, on the carbide at about 700°C.
Beryllium iodide, as obtained in the sublimed state, consists of colorless crystals, which are quickly decomposed in moist air. Its specific gravity at 15°C is close to 4.20 g/cm3. It begins to sublime below its melting point which is 510°C. The melted iodide boils between 585 and 595°C. It is insoluble in benzene, toluene, spirits of turpentine, and but slightly soluble in carbon disulphide. The slightest trace of water attacks it immediately, but if it is first fused, its sensitivity to water is much less. It can be distilled without alteration in dry hydrogen, nitrogen or carbon dioxide. At this point in time, the structure BeI2 has not been published.
