Product Name:  

Phosphoric Acid 75%, 81%, 85% (PA 75%, 81%, 85%)





Food Grade


Phosphoric Acid   is a colorless syrup-like thick liquid. It is easy to soluble in water and ethanol, odorless and with sourness. Its melting point is 42.35 oC. After it is heated to 300 oC, it will lose water to generate pyrophosphoric acid and metaphosphoric acid. It can be used as sour agent, although it is not as good as organic acid in flavor, because of its sour intensity, therefore it is suitable for some non-fruit drink which is unfavorable to usecitric acid. Phosphoric acid used as normal human body composition, it is necessary ingredients for bones, teeth and a variety of enzymes. 


Industrial Grade


Phosphoric Acid   is a thick clear or with light-colored liquid, odorless and with heavy sourness. Melting point is 42.35 oC, the boiling point is 213 oC (lost 1/2 water) it will generates pyrophosphoric acid. When heated to 300 oC it will generates metaphosphoric acid. Phosphoric Acid  is easy to soluble in water and soluble in ethanol. It’s acidity is weaker than strong acid such as: sulfuric acid, hydrochloric acid and nitric acid but stronger than the weak acid acetic acid and boric acid. It can stimulate the skin cause inflammation and damage tissues. Heated Concentration of phosphoric acid in porcelain has erosion and hygroscopicity.
