Production Of Dicalcium Phosphate With Sulfuric Acid Pdf

dicalcium phosphate production process

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

Process for producing phosphoric acid and dicalcium

The sulfuric acid requirement for production of the dicalcium phosphate as the sole product can be calculated from the results shown in Tables 1, 2, 3 and 4, when a single staged association is carried out under conditions that give a 70% conversion of 2 SO 4 2

Production of dicalcium phosphate or monocalcium

A method of producing dicalcium phosphate from calcium phosphate includes reacting the calcium phosphate with a mineral acid such as sulphuric acid to produce a calcium salt and phosphoric acid. The calcium salt may then be hydrolyzed to form a calcium alkali which may then be reacted with the phosphoric acid to produce dicalcium phosphate.
