Genel Bakış

Food-grade phosphoric acid is produced by the thermal (furnace) process, burning elemental phosphorus in air and absorbing the resulting P₂O₅ in water. Unlike the cheaper wet process used for fertilizers, the thermal process yields high-purity acid suitable for food and beverage applications. Phosphoric acid is the characteristic acidulant in cola beverages, providing the sharp, tangy taste. It is also used in processed cheese, jams, and as a pH adjuster in numerous food products.

Kimyasal Süreç

Elemental phosphorus (P₄) is burned in excess air at 1,500-1,800 degrees C to form phosphorus pentoxide (P₄O₁₀). The hot gas is hydrated by spraying with dilute phosphoric acid in a stainless steel absorption tower, producing concentrated phosphoric acid (75-85% H₃PO₄). The product is cooled, polished, and tested to meet food-grade specifications.

P₄ + 5O₂ → P₄O₁₀ (ΔH = −2,984 kJ/mol)
P₄O₁₀ + 6H₂O → 4H₃PO₄

Hammaddeler

  • Elemental phosphorus (P₄) — Electric arc furnace reduction of phosphate rock (Reactant)
  • Air (O₂) — Atmosphere (Oxidant)
  • Water (H₂O) — Purified water (Hydration medium)

Son Ürünler

  • Food-grade phosphoric acid (H₃PO₄) — Cola beverages, processed foods, pH adjustment (75-85% concentration, food-grade purity)

Environmental Impact

The thermal process is energy-intensive, requiring electricity for phosphorus production in electric arc furnaces. However, it produces minimal waste compared to the wet process, which generates large quantities of phosphogypsum. Fluorine emissions from phosphate rock require scrubbing.

Güvenlik Hususları

Son İnovasyonlar

Membrane purification of wet-process phosphoric acid is emerging as a lower-cost alternative to the thermal process for food-grade production.
Superphosphoric acid (105% H₃PO₄ equivalent) production for concentrated liquid fertilizers uses similar technology.
