It is hygroscopic. It decomposes above 300 °C to release oxygen and leave sodium chloride. Several hundred million tons are produced annually, mainly for applications in bleaching paper.〔 ==Synthesis== Industrially, sodium chlorate is produced by the electrolysis of a hot sodium chloride solution:〔Helmut Vogt, Jan Balej, John E. Bennett, Peter Wintzer, Saeed Akbar Sheikh, Patrizio Gallone “Chlorine Oxides and Chlorine Oxygen Acids” in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH. 〕 :NaCl + 3 H2O → NaClO3 + 3 H2: This reaction progresses in heat (at least 70 degrees Celsius), and controlled pH. In lower temperature or with high pH another reaction progresses: 2 NaCl + H2O → NaClO + NaCl + H2 The Chloralkali process is an industrial process for the electrolytic production of sodium hydroxide and chlorine. It can also be synthesized by passing chlorine gas through a solution of sodium hydroxide. It is then purified by crystallization. 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「Sodium chlorate」の詳細全文を読む スポンサード リンク
