Application
Ammonium bromide may be used in the preparation of organic ammonium tribromides. It may also be used as a reagent during the transformation of benzyl derivatives of halides, amines, alcohols, and aldehydes into respective nitriles via oxidation.
General description
Laser excited Raman spectral study reveals that 1?0 torsional transitions of the NH4+ ion in phase III of NH4Br were observed at 331cm-1. Neutron diffraction studies have been conducted to evaluate the P-T phase diagram of NH4Br and its deuterated form (ND3Br).

A two-phase liquid-liquid extraction process is presented which is capable of extracting water-soluble single-walled carbon nanotubes into an organic phase. The extraction utilizes electrostatic interactions between a common phase transfer agent and the sidewall functional groups on the nanotubes. Large
