Ammonium Bifluoride

CAS：1341-49-7

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.
