| Application: | 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. |
