Aplicação

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.
• As a hydrogen-bond acceptor along with levulinic acid as a hydrogen-bond donor for the preparation of deep eutectic solvents to separate toluene from toluene/n-hexane mixtures.
• To prepare ionic semiclathrate hydrates.
