TETRAPENTYLAMMONIUM BROMIDE Chemical Properties,Usage,Production

Chemical Properties

WHITE SHINY FLAKES

Uses

Tetrapentylammonium bromide can be used:

  • As a versatile structure-directing agent for the synthesis of Zeolite-like heterobimetallic cyanide frameworks.
  • As an alkylating agent for rhodium(I)-catalyzed alkylation reaction of benzylic amines and for N-alkylation of azaheterocycles.
  • As a precursor to prepare a Cobalt-complex, {[(Pentyl)4N]3CoBr3}Cl2, which is used as a catalyst in the synthesis of multiwalled carbon nanotubes (MWCNTs).


Electrochemical synthesis of stable graphite intercalation compounds (GICs) containing tetrapentylammonium cations has been reported.

General Description

Tetrapentylammonium bromide is a quaternary ammonium salt with pentyl chains and a bromide counterion, which is generally used as a phase transfer catalyst.

Purification Methods

Crystallise it from pet ether, *benzene or acetone/ether mixtures and dry in vacuum at 40-50o for 2 days. It is used in ion-paired chromatography (Sagara et al. J Chromatogr 328 289 1985). [Beilstein 4 IV 677.]
