설명

애플리케이션

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.

It can also be used as:

• A promoter in the enantioselective hydrogenation of an unprotected β-enamine amides.
• A pH-adjuster in the preparation of waterborne glucose silicone resin.
