Taylor, G. R.; Gesser, H. D.; Dunn, G. E. published the artcile< Pyridine-catalyzed halogenation of aromatic compounds. II. Study of the bromine adducts of pyridinium bromide using differential scanning calorimetry and isothermal gravimetric analysis>, COA of Formula: C19H34O2, the main research area is pyridine hydrobromide bromine adduct phase; system bromine pyridine hydrobromide.
The composition and m.ps. of the Br adducts of pyridinium bromide were determined by differential scanning calorimetry. The adducts are described in terms of stoichiometric mixtures of pyridinium bromide and pyridinium tribromide, or in terms of a general formula PyHBr(Br2)n where n equals 1/3, 1/2, 2/3, 1, 3, 6, 18. Pyridinium bromide picks up Br isothermally in an apparatus for thermogravimetric anal. in a stepwise manner with a plateau for each of the above adducts plus one with n equal to 3/2. This provides valuable confirmation of the compositions of adducts deduced from conventional phase diagrams.
