Manufacturer Good Price Ammonium Bifluoride CAS: 1341-49-7

short description:

Ammonium hydrogen fluoride is also known as acid ammonium fluoride. The chemical formula NH4F HF. Molecular weight 57.04. White deliquous hexagonal crystal, poisonous. It is easy to delix. The relative density is 1.50, the melting point is 125.6℃, and the refraction is 1.390. Can sublimate, corrosive to glass, hot or hot water will decompose. Soluble in water, slightly soluble in alcohol. Aqueous solution is strongly acidic, can corrode glass Chemicalbook glass, corrosive to skin. Gaseous ammonia was added to 40% of the hydrofluoric acid, then cooled and crystallized.

Preparation method: 1 mole of ammonia water to absorb 2 moles of hydrogen fluoride, and then cooling, concentration, crystallization.

Uses: Used as chemical reagent, earthenware and glass etching, electroplating, brewing industry, fermentation industry preservative and bacterial inhibitor, etc. It is also used in beryllium smelting and ceramic manufacturing.

Chemical Properties：White or colorless transparent rhombic crystal system crystal, the product is flake, slightly sour taste. Slightly soluble in alcohol, easily soluble in cold water, decomposition in hot water. Water is strongly acidic when dissolved.

Applications of Ammonium Bifluoride

1. Surface treatment agents for glass etching, disinfection agent, preservatives, metal cymbals, and silicon steel plates are also used to make ceramics and magnesium alloys.

2. Can be used as chemical reagents, glass etching (often combined with hydrofluoric acid), fermented industrial disinfection agent and preservatives, solvents that are oxidized, and surface treatment agents of silicon steel plates. ChemicalBook is also used to make ceramics and magnesium alloys, boilers to clean the water system and steam system, and the acidification of oil field sand oil. It is also used as alkylated and heterogeneous catalyst components.

3. For oil field acidification treatment, manufacture of magnesium and magnesium alloys. For the light of glass, cream, etching agent, used as wood protective agents, aluminum optical agents, textile industries are used as rust removal agents, and can also be used for electroplating, electronics industry, as an analytical reagent.

4. Used as analytical reagents and bacterial inhibitors.

5. Analysis reagent. Used for ceramic and glass surface. Disinfection. Preparation of hydrogen fluoride in the laboratory. plating.
