|Section2= |Section3= }} Hexol is the name for various salts of a coordination complex that has historical significance. The salts were the first synthetic non-carbon-containing chiral compounds.〔Miessler, G. L. and Tarr, D. A. ''Inorganic Chemistry'', 3rd ed., Pearson/Prentice Hall publisher, ISBN 0-13-035471-6.〕 The sulfate salt has the formula (SO4)3. == Preparation and optical resolution== Salts of hexol were first described by Jorgenson. The salt is prepared by heating ()3+ with dilute base such as ammonia followed by precipitation of the sulfate salt: :4 ()3+ → 6+ + 4 NH4+ + 2 H+ + 2 H2O Depending on the conditions one obtains the 9-hydrate, the 6-hydrate, and the 4-hydrate. These salts exists as dark brownish-violet or black tabular crystals. The salts has low solubility in water. The cation can be quantitatively precipitated from its yellow-gray chromate and hexachloroplatinate salts. When treated with concentrated hydrochloric acid, hexol converts to ''cis''-diaquotetramminecobalt(III) sulfate. In boiling dilute sulfuric acid, hexol degrades with evolution of oxygen and nitrogen. 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「hexol」の詳細全文を読む スポンサード リンク
