Description
Tetrabutylphosphonium bromide (TBPB) is a quaternary salt which can be used:
• As a medium to disperse ruthenium catalyst for the synthesis of ethylene glycol from synthesis gas via ruthenium melt catalysis.
• As a catalyst supported on silica or alumina for the halogen exchange reaction to synthesize alkyl bromide from alkyl chloride.
• To synthesize various ionic liquids on mixing with different proportions of 1,3-dimethylurea for capturing NO gas
