1. Precipitation Method:
Synthesis using ferrous iron source: Weigh equal amounts of ferrous sulfate and phosphoric acid, prepare a solution with distilled water, control the reaction temperature at 70℃, add excess hydrogen peroxide, adjust the pH to 1.5 with ammonia, filter, wash, and dry at 80℃ after 15 min to obtain the FePO4·xH2O product.
Synthesis using ferric iron source: Weigh equal amounts of ferric nitrate and ammonium dihydrogen phosphate, prepare a solution, control the temperature at 70℃, adjust the pH to 1.5 with ammonia, filter, wash, and dry at 80℃ after 15 min to obtain the product.
2. Hydrothermal Method:
Synthesis using ferrous iron as a source: Weigh equal amounts of ferrous sulfate and phosphoric acid, prepare a solution with distilled water, control the reaction temperature at 70℃, add excess hydrogen peroxide, a large amount of light yellow precipitate is produced, adjust the pH to 1.5 with ammonia, and after reacting for 15 min, transfer to a hydrothermal reactor, and react at 120℃, 150℃, and 180℃ respectively. After hydrothermal reaction for 6 h, filter, wash, and dry at 80℃ to obtain the product. Alternatively, at 150℃, the product is obtained by controlling the time at 2 h, 6 h, and 10 h respectively, following the same method.

After filtration, wash, and dry at 80℃, the product is obtained. 3. Add wet-process phosphoric acid and ferrous sulfate simultaneously to a three-necked flask in a constant-temperature water bath. Control the stirring rate, maintain a certain reaction temperature and reaction time, add excess hydrogen peroxide, adjust the pH with ammonia until a large amount of white precipitate appears, stir, allow to settle, cool to room temperature, filter, wash, and dry to obtain light yellow IRON(III) PHOSPHATE DIHYDRATE powder. The equation is as follows: 2H₃PO₄ + 2FeSO₄ + H₂O₂ → 2FePO₄ → + 2H₂SO₄ + 2H₂O |

Iron(III) phosphate dihydrate (FePO4 x 2H2O) can be used as a catalyst in the synthesis of:
- 3,4-dihydropyrimidin-2(1H)-ones and thiones by reacting with aldehydes, β-ketoesters and urea/thiourea via one pot-three component Biginelli reaction.
- Methyl methacryalate (MMA) by oxidative dehydrogenation of methyl iso-butarate (MIB).
It can be also used in the synthesis of carbon coated lithium iron phosphate (LiFePO4) as the cathode material for lithium ion batteries. It is also used as a key ingredient in preparing phosphate glass fibers. | [reaction suitability]
