Compressed-liquid densities of Dimethyl Carbonate + Heptane at Three Compositions



Stephanie L. Outcalt, Arno Laesecke


Compressed-liquid densities of the binary system dimethyl carbonate + heptane have been measured with a vibrating-tube densimeter over the temperature and pressure ranges of 270 K to 470 K, and 1 MPa to 50 MPa at three compositions of the mixture. The measurements are part of an effort to better understand the molecular interactions of polar/non-polar mixtures. These types of mixtures often exhibit very non-ideal behavior. By measuring the mixture at three compositions and over a large range of temperature and pressure, the non-ideality can be assessed. There are no compressed-liquid density data for this binary system in the literature, thus data reported here are compared to literature data at atmospheric pressure to establish their quality.
