The densities and viscosities of aqueous solutions of Genosorb 1753 (Selexol) were measured in the range (298.15 to 343.15) K. Refractive indices in the range (293.15 to 333.15) K and surface tensions in the range (298.15 to 323.15) K were also measured. Genosorb 1753 is a widely used physical solvent, a mixture of polyethylene glycol dimethyl ethers. All the experimental data were correlated using polynomials as a function of the temperature and concentration.
