|Section2= |Section3= |Section8= }} Monosodium phosphate (MSP), also known as anhydrous monobasic sodium phosphate and sodium dihydrogen phosphate, is an inorganic compound of sodium with dihydrogen phosphate (H2PO4−) anion. One of many sodium phosphates, it is a common industrial chemical. It exists as an anhydrous salt, as well as mono- and dihydrates.〔Klaus Schrödter, Gerhard Bettermann, Thomas Staffel, Friedrich Wahl, Thomas Klein, Thomas Hofmann "Phosphoric Acid and Phosphates" in ''Ullmann’s Encyclopedia of Industrial Chemistry'' 2008, Wiley-VCH, Weinheim. 〕 ==Production and reactions== The salt is obtained by partial neutralization of phosphoric acid. The pKa of monosodium phosphate is 6.8-7.2 (depending on the physicochemical characteristics during pKa determination).〔Salaun, F.: ("Influence of mineral environment on the buffering capacity of casein micelles" ), "Milchwissenschaft", 62(1):3〕 Heating this salt above 169 °C gives the corresponding sodium acid pyrophosphate: :2 NaH2PO4 → Na2H2P2O7 + H2O 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「monosodium phosphate」の詳細全文を読む スポンサード リンク
