摘要：

Experimental density, viscosity, speed of sound, and refractive index for aqueous solutions of 1-ethyl-2-pyrrolidinone were measured over the entire composition range and at different temperatures (293 to 323) K. Excess properties and deviations have been calculated, and their dependence on composition was mathematically represented by a Redlich-Kister-type equation. The hydration of pyrrolidinone molecules plays an important role in the thermophysical behavior of this mixture.
