ABSTRACT
Nonsteroidal anti-inflammatory drugs (NSAIDs) exhibit analgesic, anti-inflammatory, antipyretic and platelet inhibitory properties. Density and viscosity of salicyl amide, salicylic acid, and acetyl salicylic acid in water, methanol, and ethanol at T = (293.15 to 313.15) K have been measured in a molality range of (9.7*10-3 to 32.5*10-3) mol*kg-1 with the help of a commercially available vibrating-tube densimeter and viscometer. From the density data, apparent molar volume (V,1), partial molar volume (Vm?), thermal expansion coefficient (??2), and (?2Vm?/?T2) are calculated. The viscosity data are analyzed by the Jones-Dole equation to determine the values of the viscosity B-coefficient.
