Description

General description

Sodium hydroxide also known as caustic soda is a water soluble base with a wide range of industrial applications.

Application

Sodium hydroxide may be used in the following processes:
• Titration methods.
• Dissolution testing.
• As a base for adjusting pH.
• As a reducing agent to initiate the synthesis of resin-supported silver nanoparticles.
• As an alternative to sodium hydride in the carbon-11 methylation reaction in the synthesis of [11C]diprenorphine.
• Preparation of bead cellulose loaded with iron oxyhydroxide (BCF).
• Synthesis of polyethyleneimine-sodium xanthogenate (PEX).
• Pretreatment of thickened waste activated sludge during anaerobic digestion.
• Struvite precipitation recycling technology.
• Production of sewage-sludge-based activated carbons.
• Preparation of β-cyclodextrin (β-CD)/cellulose hydrogels.
• Prion inactivation during industrial decontamination procedure.
• Pretreatment of sugarcane bagasse for the sugar recovery.
• In the Impinger to remove acidic gases.
