Densities and Isothermal Compressibilities at Pressures up to 20 MPa of the Systems 1-Methyl-2-pyrrolidone + 1-Chloroalkane or + α,ω-Dichloroalkane

Abstract

Densities of pure 1-methyl-2-pyrrolidone were measured at (288.15, 298.15, 308.15, and 318.15) K at pressures up to 20 MPa, and from them isothermal compressibilities were obtained. Densities for 1-methyl-2-pyrrolidone + 1-chlorobutane, or + 1-chlorohexane, or + 1-chlorooctane, or + 1,2-dichloroethane, or + 1,4-dichlorobutane, or + 1,6-dichlorohexane at 298.15 K and at pressures up to 20 MPa were measured, and isothermal compressibilities were obtained.
