설명

일반 설명

Sodium hydroxide (caustic soda) is an inorganic source of hydroxide ions that can be used to alkylate phenols, alcohols, aldehydes, and ketones. NaOH can also be used to convert amides into amines, to produce dichlorocarbenes, and in saponification of carboxylic acid derivatives.

애플리케이션

Sodium hydroxide may be used:

• As a deprotonator in the synthesis of nanoparticles of zeolitic imidazolate framework (ZIF-94).
• As a precipitating agent in the synthesis of NiO (nickel oxide) nanoparticles using nickel nitrate.
• As a pH controller in the synthesis of zinc chromite (ZnCr₂O₄) oxide powder from zinc nitrate and chromium nitrate by hydrothermal process.
