Liquid densities of acetone and n-heptane and excess volumes of the binary system in a wide temperature and pressure range
Liquid densities of acetone and n-heptane and of the binary system in a temperature range from 318 to 438 K and pressures up to 130 MPa have been measured using an Anton Paar DMA HPM vibrating tube densimeter. The experimental densities were correlated with the TRIDEN-system. From the densities of the pure compounds and the mixtures the excess volumes for the binary system have been derived in the temperature range from 338 to 418 K and pressures up to 130 MPa.
