其他信息

毒性:参见工业磷酸。
Pyrophosphoric acid has been shown to enhance the rate of pyrophosphate hydrolysis by nonenzymatic catlysis and by inorganic pyrophoshatase. Pyrophosphoric acid can be used for the preparation of vanadyl pyrophosphato methoxide cluster anion. Pyrophosphoric Acid is used in anion binding of inorganic phosphates due to its ability to form complexes.

方法一:焦磷的制造有，将市售85%磷酸脱水浓缩、将五氧化二磷溶解于85%磷酸的方法、磷酰氯和85%磷酸反应的方法。 85%磷酸浓缩法将市售85%磷酸避开局部过热，在减压下加热到约180℃脱水(100g 85%磷酸的失重约为25～30g)，制得焦磷酸。将P2O5溶解于85%磷酸的方法在激烈搅拌下，按计算量(100g85%磷酸添加95～100g P2O5)将P2O5一点一点地加到磷酸中，边加热边溶解直至透明。向生成的焦磷酸加水将P2O5含量调整到76%～79%左右。将焦磷酸自然放置(要继续防潮)则形成结晶，在冰冷却下需要两天到三天形成结晶，制得焦磷酸。在液体焦磷酸中加晶种的方法这是大量生产高纯度结晶焦磷酸(I型或Ⅱ型)的方法，将市售含84%P2O5的连多磷酸(也叫作116%磷酸)用水稀释作成液体焦磷酸(P2O579.76%)，添加适量(以重量计10%～50%)的I型或Ⅱ型焦磷酸晶种，在干燥氮气流中以防湿，在30～50℃搅拌下，经过60～180 min的诱导期，就可以制得结晶焦磷酸，纯度＞95%。
