Non Volatile Mineral Acid Phosphoric Acid in Pharmaceuticals

  • phosphoric acid

  • XLW

Product Description


Product Description

Introduction (  Phosphoric Acid CAS No.7664-38-2)
Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H3PO4. It is normally encountered as a colorless, syrup of 85% concentration in water. The pure compound is a colorless solid.Phosphoric acid is commonly encountered in chemical laboratories as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. Although phosphoric acid does not meet the strict definition of a strong acid, the 85% solution can still severely irritate the skin and damage the eyes.
Molecular formula:H3PO4
Molecular weight:97.99
Properties: Colorless transparent viscous liquid. It is odorless, very sour, melting point 42.35 C, soluble in water, soluble in
ethanol. It can stimulate skin inflammation, destroy body tissues, and has hygroscopicity.

Product Storage

Keep in a tightly closed container. Protect from physical damage. Store in a cool, dry, ventilated area away from sources of heat, moisture, incompatibilities, and direct sunlight. Corrosive to mild steel. Store in rubber lined or 316 stainless steel designed for phosphoric acid. Do not wash out container and use it for other purposes. When diluting, the acid should always be added slowly to water and in small amounts. Never use hot water and never add water to the acid. Water added to acid can cause uncontrolled boiling and splashing. Protect from freezing. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.

Function and Application:

Phosphoric acid is an inorganic strong acid, and it is an important chemical raw material. Its chemical uses are as follows:

1. Process metal surfaces to generate insoluble phosphate films to protect the metal from corrosion.

2. Mix with nitric acid as a chemical polishing agent to improve the smoothness of metal surfaces.

3. Phosphate esters are the raw materials for producing washing products and insecticides.

4. Raw materials for producing phosphorus containing flame retardants.
