Description

General description

Tetrakis(decyl)ammonium bromide is a cationic surfactant.[1]

Tetrakis(decyl)ammonium bromide is a quaternary ammonium/phosphonium salt used as an ion-pair agent, and for the modification of bentonite. [2] [3]

[1]

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.[4]
• Gold ions from an aqueous to an organic phase during the synthesis of gold nanoparticles.[5]
• The alkylation of (E)‐pyridine aldoximes and (E)‐ketoximes with dihalohydrins.[6]

It has been used as a reactant in the synthesis of ionic monomers to produce soft thermoplastic polyurethanes(TPU).[7]
