ABSTRACT
In the present paper, speed of sound and isentropic compressibility of aqueous solutions of two amines, pyrrolidine (C4H9N) and piperidine (C5H11N), at several temperatures (293, 303, 313, and 323 K) have been determined. The study of these mixtures has covered its complete composition range. Speed of sound shows a maximum value when the presence of amines increases in the mixture. A Redlich-Kister type equation was employed to fit the excess properties.
