With the thermometric titration method, titration of amines with hydrochloric acid, for example, aliphatic amines (mono-, di-, tri-ethyl; n-, iso-, di-propyl; n-, iso-, sec-, tert-butyl), aromatic amines (aniline and its derivatives) and heterocyclic basic compounds (pyridine, picoline, piperidine, pyrrolidine, aminopyrine), have been examined as the acid-base reactions. In this study, Cobble automatic thermoanalyzer and autoburet were employed as the apparatus, and the titrations have been carried out at room temperature. Volumetric end points were accurate to 3% in the range 7.5×(10)^<-3>M to 5×(10)^<-2>M for the almost amines except mono-ethylamine. Ethanol-water has been used as a medium for aromatic amines, and heat of dilution gave some effects on titration curves, but end point of the titration could be detected clearly.
