If all for hydrogens of an ammonium ion are replaced with alkyl or aryl groups then an ionic quaternary salt is formed. The right column of Figure 1 shows bifunctional quats (biquats), which were synthesized by a double nucleophilic substitution reaction, as described in Figure S1 in the Supplementary Material. the quaternary ammonium salt reacts with AgOH, silver halide and quaternary ammonium alkali will be formed [1] as follow: R 4N +X-+ AgOH R 4N OH-+AgX ↓ CTAB is one of the quaternary ammonium salts. # 1 below shows a typical Hofmann elimination a positively charged polyatomic ion the.
