Ammonium fluoride is a white crystalline solid that is soluble in water and non-flammable. It is corrosive to aluminum. It is mainly used for chemical analysis, brewing and wood preservation.
It corrodes the glass and is corrosive to the skin. It can be used as a chemical reagent, a glass etchant (participating in hydrofluoric acid), a disinfectant and a preservative in the fermentation industry, a solvent for metal ruthenium and a surface treatment agent for silicon steel sheets by ruthenium oxide. It can also be used to make ceramics, magnesium alloys, boiler feed water systems and steam generation systems, as well as oil sands acid treatment agents for cleaning and fouling. It is also used as a component of alkylation and isomerization catalysts.
The production process of ammonium hydrogen fluoride usually first produces ammonium fluoride and then further produces hydrogen fluoride by hydrogen fluoride. If not managed properly, it will become a mixture of ammonium fluoride and ammonium hydrogen fluoride, which is easily decomposed into ammonium hydrogen fluoride.
CAS No: 12125-01-8
Properties: 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.
