It is a white, granular or crystalline solid, highly soluble in water producing an alkaline solution. TSPs are used as cleaning agent, lubricant, food additive, stain remover and degreaser.〔 The item of commerce is often partially hydrated and may range from anhydrous Na3PO4, to the dodecahydrate, Na3PO4·12 H2O. Most often found in white powder form, it can also be called trisodium orthophosphate or simply sodium phosphate. == Production == Trisodium phosphate is produced by neutralization of phosphoric acid using sodium hydroxides, often with sodium carbonate. Carbonate can only produce disodium phosphate: : Na2CO3 + H3PO4 → Na2HPO4 + CO2 + H2O : Na2HPO4 + NaOH → Na3PO4 + 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「trisodium phosphate」の詳細全文を読む スポンサード リンク
