Density, ultrasonic velocity and viscosity of caffeine a pharmaceutically significant drug in water at four temperatures were measured. The partial molar volume ($Vo), partial molar compressibility (d,o) and the viscosity B coefficient were calculated from the experimental data. Values of QIVO and $

The partial molar isentropic pressure coefficients at infinite dilution k a S, 2 =-(1V a 2 /1p)S , where V a 2 is the partial molar volume at infinite dilution, have been determined for six N-acetyl amino acid and peptide amides in aqueous solution at the temperature 298.15 K. The results obtained h
Partial molar volumes at infinite dilution provide a convenient test of theoretical models of aqueous solutions. In this communication, previously published experimental results of the apparent molar volumes for NaCl, NaBr, LiCl, and CsBr at near-critical conditions were Ž extrapolated to infinite d
Relative densities and massic heat capacities have been determined for the amino acids L-lysine monohydrochloride and L-arginine monohydrochloride in aqueous solution at the temperatures T = (288. 15, 298.15, 313.15, and 328.15) K. These data have been used to calculate apparent molar properties whi
