Description

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.

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).
