Application

Tetrabutylphosphonium hydroxide (TBPH) can be used:
  • To convert poorly water-soluble acidic APIs into TBP ionic liquids (IL).
  • As a cation source in the synthesis of Good′s buffer ionic liquids (GB-ILs) via an acid−base neutralization reaction with Good′s buffer anions.
  • To synthesize tetrabutylphosphonium acetate, which along with Cu2O-nanoparticles forms an excellent catalyst system for protodecarboxylation reactions.

Long-term exposure to toxic chemicals often has deleterious effects on aquatic organisms. In order to support appropriate environmental management of chemicals, a mathematical model was developed to characterize the effects of chemicals on multigenerational population dynamics in aquatic animals.

Factors contributing to the different distribution behaviour of cytochrome c were investigated in a biphasic tetrabutylphosphonium 2,4,6-trimethylbenzenesulfonate and potassium phosphate buffer system, which shows a lower critical solution temperature. To change charge balance and hydrophobicity of cytochrome c, surface modification
