Compressed-liquid densities of two highly polar + non-polar binary systems
Stephanie L. Outcalt, Arno R. Laesecke
The binary systems ethanol + 2,2,4-trimethylpentane and 2-butanol + 2,2,4-trimethylpentane were studied as models for blends of gasoline with biofuels. Their densities were measured with a vibrating-tube densimeter at compressed-liquid states of three compositions of each of the binary systems. The temperature and pressure ranges of the measured data are from 270 K to 470 K, and 0.5 MPa to 50 MPa. There are no compressed-liquid density data for the binary system ethanol + 2,2,4-trimethylpentane in the literature, thus data reported here are compared to literature data at atmospheric pressure in order to establish their quality. No literature data for the system 2-butanol + 2,2,4-trimethylpentane were found, thus data reported here fill a void and help to further the understanding of molecular interactions in binary systems of a polar and a non-polar compound.
