Phosphoric acid

Phosphoric acid is made from Element Phosphorus (Thermol process) or Rock Phosphorus (Wet process). As wet process will introduce more impurity into product acid. Purification from green acid (wet-process acid) to product is always a technical challenge. Many projects were failed due to technical issues how to purify wet-process phosphoric acid to food grade acid.

Comparing with wet process, thermal process and can produce high purity acid including food grade and semi-conduct grade acid.  

Panchem(YN) adapts uses mature technology and have produced thermal process phosphoric acid around two decades. As the manufacture and global supplier, it’s always our goal to provide excellent products and service to our customers.

About Phosphoric acid

Phosphoric acid (also known as orthophosphoric acid ) is a mineral (inorganic) acid having the chemical formula H3PO4. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound.

orthophosphosphoric acid

The prefix ortho is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids. Orthophosphoric acid is a non-toxic acid, which, when pure, is a solid at room temperature and pressure. The conjugate base of phosphoric acid is the dihydrogen phosphate ion.


Thermal Process Phosphoric Acid

Phosphoric acid is used in metal finishing ( pre-treatment before anodizing or rust moving…etc.), phosphates production, beverages and food as pH regulator.

The phosphoric acid we produce is transparent liquid, made from element phosphorus by thermal process.


Phosphoric acid food grade

Metal Finishing : Phosphatizing compounds for rustproofing and improvement of paint bonding of steel; as the major ingredient in solutions used for the chemical and electro-chemical polishing of aluminum, stainless steel, and copper alloys; and in metal cleaning and pickling.
Chemicals Manufacture: Production of phosphate salts.

Equipment Maintenance: Descaling of boilers and heat-exchanger tubes.

Ceramics and Glass: For ceramic colors chemically-bonded fire brick for steel furnaces;

Petroleum: Polymerization of propylene; alkylating catalyst.
