Di-calcium phosphate by direct acidulation of phosphate rock

An investigation was undertaken to develop a process for producing di-calcium phosphate by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, mono-calcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, di-calcium phosphate should be formed

Dicalcium Phosphate From Rock Phosphate

Dicalcium Phosphate From Rock Phosphate Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate. •Dicalcium phosphate is usually found as the dihydrate, but it can be thermally converted to the anhydrous form. It is practically insoluble in water, with a solubility of 0.02 g per 100 mL at 25 °C. •Dicalciumphosphate (CaHPO4.2H2O) is a chemical ...

Project Report on Dicalcium Phosphate Rock -

Dicalcium phosphate shows the most commonly used production method is known as the “wet acid” route in which rock phosphate is reacted with sulphuric acid to produce phosphoric acid. After concentration and purification to reduce the level of undesirable elements, this phosphoric acid is reacted with a calcium source such as quick lime or limestone to produce dicalcium phosphate.

Dicalcium phosphate - Wikipedia

Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2 – anion involves the removal of two protons from phosphoric acid, H 3 PO 4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate. Dicalcium phosphate is used as a food additive, it is found in some ...
