VOLUMETRIC PROPERTIES OF GASEOUS ACETONE

Experimental compressibilities of gaseous acetone for the temperature range 25° to 150° C. at 25° C. intervals were obtained from a Burnett PVT apparatus for the pressure range 1 to 105 p.s.i.a. Second, third, and fourth virial coefficients are presented which provide an adequate fit of the experimental data. Computed values of the equilibrium constant for dimerization are in good agreement with those calculated from heat capacity measurements. The experimental data are compared with the Stockmayer intermolecular potential energy model and the polar correlation of Eubank and Smith. The experimental apparatus, errors in the compressibility results, and acetone purity are discussed. Equations for correction of Burnett PVT data for adsorption of gas molecules to the metallic walls of the cell are presented. © 1968, American Chemical Society. All rights reserved.
