|Section2= |Section4= |Section7= |Section8= }} Lithium iodide, or LiI, is a compound of lithium and iodine. When exposed to air, it becomes yellow in color, due to the oxidation of iodide to iodine.〔(【引用サイトリンク】 url=http://www.espimetals.com/msds's/lithiumiodide.pdf )〕 It crystallizes in the NaCl motif.〔Wells, A.F. (1984) ''Structural Inorganic Chemistry'', Oxford: Clarendon Press. ISBN 0-19-855370-6.〕 Various hydrates are also known.〔Wietelmann, Ulrich and Bauer, Richard J. (2005) "Lithium and Lithium Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry'', Wiley-VCH: Weinheim. .〕 ==Applications== Lithium iodide is used as an electrolyte for high temperature batteries. It is also used for long life batteries as required, for example, by artificial pacemakers. The solid is used as a phosphor for neutron detection.〔 〕 It is also used, in a complex with Iodine, in the electrolyte of dye-sensitized solar cell. In organic synthesis, LiI is useful for cleaving C-O bonds. For example it can be used to convert methyl esters to carboxylic acids:〔Charette, André B.; Barbay, J. Kent and He, Wei (2005) "Lithium Iodide" in ''Encyclopedia of Reagents for Organic Synthesis'', John Wiley & Sons. 〕 :RCO2CH3 + LiI + H2O → RCO2H + LiOH + CH3I Similar reactions apply to epoxides and aziridines. Lithium iodide was used as a radio contrast agent for X-ray computed tomography imaging studies. Its use was discontinued due to renal toxicity and replaced with organic iodine molecules. Inorganic iodine solutions suffered from hyperosmolarity and high viscosities. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Lithium iodide」の詳細全文を読む スポンサード リンク
