Abstract

Densities of methyl tert -butyl ether (MTBE), ethyl tert -butyl ether (ETBE), and diisopropyl ether (DIPE) have been measured with a computer-controlled high-temperature, high-pressure vibrating tube densimeter system (DMA-HDT) in the liquid state. The uncertainty in the density measurement was estimated to be lower than ±0.2 kg·m -3 . The densities were measured for temperatures from 273 K to 473 K and pressures up to 40 MPa for MTBE (337 data points) and for ETBE (364 data points) and up to 35 MPa for DIPE (328 data points), which covers the density range between (459 and 792) kg·m -3 for MTBE, between (494 and 792) kg·m -3 for ETBE, and between (471 and 774) kg·m -3 for DIPE. The experimental data were correlated with the new three-dimensional density correlation system (TRIDEN) and compared with published data.
