Application
Ammonium chloride can be used as a catalyst:
- To synthesize 3,4-dihydropyrimidin-2-(1H)-ones via solvent-free Biginelli-condensation reaction.
- For the aldol condensation of carbonyl compounds.
- In the thia-Michael addition reaction of thiols to different α-enones.
- A promoter in the enantioselective hydrogenation of an unprotected β-enamine amides.
- A pH-adjuster in the preparation of waterborne glucose silicone resin.

In natural environments such as atmospheric aerosols, organic compounds coexist with inorganic salts but, until recently, were not thought to interact chemically. We have recently shown that inorganic ammonium ions, NH(4)(+), act as catalysts for acetal formation from glyoxal, a
