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).

A novel aqueous two-phase system (ATPS) only containing Gemini surfactant ethanediyl-1,2-bis(dodecyldimethylammonium bromide) and an inorganic salt sodium bromide was designed, and the physicochemical properties of the ATPS were investigated systematically. The results have shown that the coexisting two phases, one
