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.
