|Section2= |Section3= |Section7= |Section8= }} Ammonium carbonate is a salt with the chemical formula (NH4)2CO3. Commercial samples labelled ammonium carbonate no longer contain this compound, but a mixture that has similar ammonia content. Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. It is also known as baker's ammonia and was a predecessor to the more modern leavening agents baking soda and baking powder. It is a component of what was formerly known as sal volatile and salt of hartshorn.〔 ==Production== Ammonium carbonate is produced by contacting carbon dioxide and aqueous ammonia. About 7000 tons/year were produced as of 1997.〔Karl-Heinz Zapp "Ammonium Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry'' 2012, Wiley-VCH, Weinheim. 〕 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「Ammonium carbonate」の詳細全文を読む スポンサード リンク
