什么是磷酸盐?

二钙化物Phosphate is calcium phosphate having the chemical formula CaHPO₄及其二氢。该化合物的化学配方是CAHPO₄。这molar massof this compound is 136.06 g/mol. It is an odorless compound that appears as a white power. Thedensityof Dicalcium phosphate varies with its hydration. When anhydrous, the density of Dicalcium phosphate is 2.92 g/cm³whereas the density of its dihydrate forms is 2.31 g/cm³。在较高的温度下，磷酸二钙分解而不是熔化。

磷酸二钙有三种可能的化学结构。

1. Dehydrate form (CaHPO₄.2H₂o）
2. Hemihydrate form (CaHPO₄.0.5h₂o）
3. Anhydrous form (CaHPO₄)

这crystal structure of Dicalcium phosphate crystals is triclinic. The IUPAC name of this compound is Calcium hydrogen phosphate dehydrate. The reactants used for the production of Dicalcium phosphate include calcium hydroxide (Ca(OH)₂) and phosphoric acid (H₃po₄）。生产过程包括通过磷酸中和氢氧化钙的中和，从而使磷酸二核作为脱水沉淀物。当其反应在60°C左右进行时，会产生无水形式。

H₃po₄+ Ca(哦)₂→ CaHPO₄

该最终产品的降解可以形成羟基磷灰石。因此，为了避免降解，将焦磷酸钠添加到反应混合物中。

磷酸二核用于制造谷物，狗零食和面条产品作为饮食补充剂。它还具有一些药物应用；用作片剂。除此之外，磷酸二硫酸二硫酸盐被用作食物添加剂，也可以在牙膏中作为抛光剂。

What is Monocalcium Phosphate?

磷酸单元是具有化学式Ca的磷酸钙（H₂po₄)₂。It is commonly found as the monohydrate form. The IUPAC name of this compound is Calcium dihydrogen phosphate. The molar mass of this compound is 234.05 g/mol. Themelting point磷酸单元的磷酸盐为109°C，沸点为203°C。但是，在较高的温度下，它分解了。

Monocalcium phosphate is prepared by using treating calcium hydroxide with phosphoric acid with a high purity. The reaction is as follows.

Ca(OH)₂+ 2 H₃po₄→ Ca(H₂po₄)₂+ 2 H₂O

这final product or the Monocalcium phosphate solid tends to convert into Dicalciumphosphate form.

这re are two main applications of Monocalcium phosphate; it is used in fertilizer production and as a leavening agent. Monocalcium phosphate or triple superphosphate is a solid that is used as a fertilizer. It is also used as a leavening agent in food industry.

What are the Similarities Between Dicalcium Phosphate and Monocalcium Phosphate?

• Both Dicalcium Phosphate and Monocalcium Phosphate are composed of phosphate anions.
• Both Dicalcium Phosphate and Monocalcium Phosphate are used in food industry.
• Both Dicalcium Phosphate and Monocalcium Phosphate compounds decompose at high temperatures.
• Both Dicalcium Phosphate and Monocalcium Phosphate compounds are produced from calcium hydroxide and phosphoric acid.
