Description

Description générale

Ammonium hydroxide is a weak base mainly used as a source to prepare other ammonium compounds like urea, ammonium carbonate and ammonium sulfate etc.

Ammonium hydroxide solution is a solution of 30-33% NH₃ in H₂O. It is a colorless liquid having a strong characteristic odor. Electrolytic deposition of silver onto vitreous carbon electrodes from ammonium hydroxide solutions by the potential step technique has been reported.

Application

Ammonium hydroxide solution may be used in the following studies:

• Preparation of magnetic nanoparticles.
• To investigate the effect of substrate on the morphology of ZnS thin films by chemical bath deposition.
• Preparation of amine functionalized cellulose nanocrystals (CNC-NH₂).
• Wet processing of the GaAs(100) surface.

Ammonium hydroxide solution may be used:

• As a medium to prepare magnetite (Fe₃O₄) nanoparticles via a modified controlled chemical coprecipitation method.
• As a solvent and reagent to prepare 4-aryl and 4-alkyl-2,6-dimethyl-1,4-dihydro-3,5-pyridinedicarboxylates via Hantzsch synthesis in a microwave cavity synthesizer.
