Introduction of Phosphoric Acid CAS 7664-38-2
Phosphoric acid, also known as Orthophosphoric Acid / O-Phosphoric Acid, is a common inorganic acid, medium strong acid, chemical formula H3PO4, molecular weight 97.994. It is not easy to volatilize, or decompose, and has almost no oxidation. It has the common property of acid. It is a ternary weak acid, weaker than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid, boric acid, etc. Phosphoric acid is easily deliquescent in the air. Pyrophosphoric acid is obtained by heating, and metaphosphoric acid is obtained by further dehydration.
Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as rust inhibitor, food additive, dental and orthopedic surgery, EDIC corrosion agent, electrolyte, flux, dispersant, industrial corrosion agent, fertilizer raw materials and components, household cleaning products, as well as chemical reagents.
Applications of Electronic Grade Phosphoric Acid CAS 7664-38-2
① Electronic grade phosphoric acid belongs to high-purity phosphoric acid, which is widely used in large-scale integrated circuits, thin film liquid crystal displays (TFT-LCD) and other microelectronic industries, mainly for chip cleaning and etching.
Its purity and cleanliness have a great impact on the yield, electrical performance and reliability of electronic components.
The lower purity is mainly used for the cleaning of LCD panel components (panel level), and the higher purity is used for the cleaning and turbidity etching (called IC level) in the production process of electronic chips.
② Electronic-grade phosphoric acid can also be used to prepare high-purity phosphate, which is the main raw material of high-purity organic phosphorus products.
③ In addition, O-Phosphoric Acid can also be used as an ultra-high purity reagent and raw material of optical fiberglass.
Production Process of Electronic Grade Phosphoric Acid CAS 7664-38-2
The thermal phosphoric acid manufacturing process adopts the "one-step" production technology. The produced phosphoric acid has stable performance and high purity.
Thermal phosphoric acid is produced by injecting yellow phosphorus into the spray gun through the phosphorus pump, and then injecting it into the combustion tower for combustion to generate phosphorus pentoxide. The phosphorus pentoxide flue gas enters the hydration tower and hydrates with ultra-pure water to generate phosphoric acid. After coarse filtration and fine filtration, it enters the aeration tower to obtain high-purity phosphoric acid.
Thermal process is generally used to prepare electronic-grade and food-grade phosphoric acid.
The main chemical reactions are as follows:
P4 + 5O2 → 2P2O5，P2O5 + 3H2O → 2H3PO4
