DENSITIES, REFRACTIVE-INDEXES, AND DERIVED EXCESS PROPERTIES OF (X(1)CH(3)COCH(3)-X(1)-X(2))CH3CH(OH)CH3) AT THE TEMPERATURE 298.15 K(X(2)CH(3)OH+(1)

Densities and refractive indices at the temperature 298.15 K of {x(1)C H(3)COCH(3) + x(2)CH(3)OH + (1 - x(1) - x2)CH3CH(OH)CH3} and of the bi naries: {xCH(3)COCH(3) + (1 - x)CH3CH(OH)CH3}, and {xCH(3)OH + (1 - x) CH3CH(OH)CH3} have been determined experimentally as a function of the mole fraction(s) at atmospheric pressure. Excess molar volumes and ch anges of refractive index on mixing were determined. Variable-degree p olynomials have been fitted in order to compare the accuracy of differ ent methods for the estimation of these results. (C) 1995 Academic Pre ss Limited
