Industrial Ammonium Hydrogenfluoride
[Molecular Formula] NH4HF2
[Molecular Weight] 57.04
[Properties]
White needle-like crystal, easy deliquescence and agglomeration, soluble in water and slight soluble in alcohol; decompose to ammonia and ammonium bifluoride in heat water, decompose to ammonia and hydrogen fluoride when being heated, its aqueous solution is acidic and can corrode glass.
[Uses]
1. Glass etchant, preservative, disinfectant, solvent for metal beryllium made of beryllium oxide, analytical reagent and surface treatment agent for silicon steel plate.
2. It is also used as an oxidant for the manufacture of ceramics and aluminum-magnesium alloys, as well as a cleaning agent for boiler feed water systems and steam generation systems.
3. Acidification treatment of oilfield sand.
4. Organic synthetic fluorinating agent.
5. Plating solution.
6. Reagents for extracting rare elements.
7. Paint industry
It is a white crystal with corrosive to skin and toxic. It is soluble in water and methanol, slightly soluble in ethanol, insoluble in propanone and liquid ammonia. When it is in hot water decomposition will occur to release ammonia and ammonium bifluoride. It is white or colorless transparent orthorhombic crystal at room temperature, with a slightly sour taste. It is easily deliquescent when heated or in hot water and decomposes into ammonia and hydrogen fluoride. Decomposed in hot water, the aqueous solution is strongly acidic. It is obtained by neutralizing anhydrous hydrofluoric acid with liquid ammonia.
Mainly used as glass etching agent, wood and wine preservative, disinfectant, zirconium drops reagent and fiber mordant and reagents to extract rare elements. Chemical reagents, glass etchants (used in conjunction with hydrofluoric acid), disinfectants and preservatives in the fermentation industry, solvents for beryllium oxide to beryllium, surface treatment agents for silicon steel sheets, and production of ceramics, magnesium alloys, aluminum alloys, etc., boilers Scale removal and elution of feedwater systems and steam generation systems, acid treatment of oilfield sands, catalysts for alkylation and alkylation of isomerized components.
