ABSTRACT

Aspirin is used as an analgesic, antipyretic, and anti-inflammatory drug. Density and viscosity of acetyl salicylic acid (2-acetoxy benzoic acid) in propan-1-ol, propan-2-ol, butan-1-ol, and butan-2-ol at temperatures in the range (293.15 to 313.15) K have been measured in a molality range of (9.5*10-3 to 31.9*10-3) mol*kg-1 with the help of a commercially available vibrating-tube densimeter and viscometer. From the density data, apparent molal volume (V), partial molal volume (Vm0), isobaric thermal expansion coefficient (a2), partial molal expansivity (E20), Hepler s constant (d2Vm0/dT2), and transfer volume (?Vm0) are calculated. The viscosity data are analyzed by the Jones-Dole equation to determine the values of the viscosity B-coefficient.
