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.[1]
• Dissolution testing.[2]
• As a base for adjusting pH.[3][4]
• As a reducing agent to initiate the synthesis of resin-supported silver nanoparticles.[5]
• As an alternative to sodium hydride in the carbon-11 methylation reaction in the synthesis of [¹¹C]diprenorphine. [6]
• Preparation of bead cellulose loaded with iron oxyhydroxide (BCF).[7]
• Synthesis of polyethyleneimine-sodium xanthogenate (PEX).[8]
• Pretreatment of thickened waste activated sludge during anaerobic digestion.[9]
• Struvite precipitation recycling technology.[10]
