Application

Tetrakis(decyl)ammonium bromide acts as a phase transfer agent for:
  • Platinum salts from aqueous to organic phase during the synthesis of platinum nanocrystals.
  • Gold ions from an aqueous to an organic phase during the synthesis of gold nanoparticles.
  • The alkylation of (E)‐pyridine aldoximes and (E)‐ketoximes with dihalohydrins.
It has been used as a reactant in the synthesis of ionic monomers to produce soft thermoplastic polyurethanes(TPU).

General description

Tetrakis(decyl)ammonium bromide is a cationic surfactant.

Tetrakis(decyl)ammonium bromide is a quaternary ammonium/phosphonium salt used as an ion-pair agent, and for the modification of bentonite.
