Description

General description

Sodium bromide, an alkaline-earth halide, is an inorganic salt. Density, viscosity and electrolytic conductivity of concentrated aqueous solutions of alkaline-earth halides have been evaluated.

Application

Sodium bromide may be used in the following studies:
• As catalyst for the microwave assisted three-component cyclocondensation of aryl aldehydes, alkyl nitriles and dimedone for the synthesis of highly functionalized tetrahydrobenzo[b]pyrans.
• To compose the aqueous two-phase system (ATPS) containing Gemini surfactant ethanediyl-1,2-bis(dodecyldimethylammonium bromide).
• Preparation of unoxidized and carboxylated pullulan, which are employed as mediators for the preparation of silver nanoparticles (AgNPs).
