Studies in Acetyl Bromide as a Polar Solvent. Part IV. Conductometric Titrations in Acetyl Bromide

Existence of solvo-acids, solvo-bases, and ansolvo-bases in acetyl bromide, as already postulated, has been confirmed conductometrically in solutions. Stannic bromide and antimony tribromide have been used as solvo-acids. Solutions of α-picoline. quinoline, isoquinoline. and dimethylaniline have been used as solvo-bases and the quaternary ammonium halides, viz., tetraethylammonium bromide, triethylbenzylammonium bromide, dimethyletlsylphenylammonium bromide, and dimethylphenylbenzylammonium bromide, have been used as ansolvo-bases. The breaks in curves corresponding to different acid/base molar ratios have been noted, indicating the formation of acid or normal salts. Most of the complexes isolated in Part III have been confirmed and the formation of numerous others has been indicated. The formation of these complexes is explained on the basis of the existence of ionic species in the solutions of acetyl bromide
