ammonium bromide salts

Preparation of Amines1 Chemistry LibreTexts

Making a quaternary ammonium salt. The final stage! The triethylamine reacts with bromoethane to give tetraethylammonium bromide a quaternary ammonium salt (one in which all four hydrogens have been replaced by alkyl groups). This time there isn''t any hydrogen left on the nitrogen to be removed. The reaction stops here.

Synthesis of quaternary ammonium salts SpringerLink

Abstract. Since the early days of phase transfer alysis (PTC), the most popular alysts have been quaternary ammonium salts (quats). Among these, tetra Hbutylammonium bromide (TBAB), introduced by Brandstrom, triethyl benzylammonium chloride (TEBA), initiated by Maskoza, and Stark''s tricaprylmethylammonium chloride (Aliquat 336 or Adogen 464) are more frequently applied.

preparation of amines chemguide

The reaction happens in two stages. In the first stage, a salt is formed in this case, ethylammonium bromide. This is just like ammonium bromide, except that one of the hydrogens in the ammonium ion is replaced by an ethyl group. There is then the possibility of a reversible reaction between this salt and excess ammonia in the mixture.
