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
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
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.

I-Chemicals-B-sulfuric acid-2 Superphosphate is manufactured by reacting insoluble phosphate rock with sulfuric acid to form a mixture of soluble mono-calcium phosphate and calcium sulphate (approximately 9% phosphorous) which is able to be used by plants.
Phosphatic raw materials are treated with phosphoric acid to obtain monocalcium phosphate which is dissociated with an organic solvent to yield high grade phosphoric acid and fertilizer grade dicalcium phosphate.

The acid concentration is critical: values higher than 10% HCl and 20% HNO3 cause blocking of the bed because of the formation of insoluble dicalcium phosphate and values lower than these cause
