Vapor Pressures, Liquid Molar Volumes, Vapor Non-Idealities, and CriticalProperties of Some Fluorinated Ethers: CF3OCF2OCF3, CF3OCF2CF2H, c-CF2CF2CF2O, CF3OCF2H, and CF3OCH3; and of CCI3F and CF2CIH

摘要

Vapor pressures, compressibilities, expansivities, and molar volumes of theliquid phase have been measured between room temperature and the critical temperature for a series of fluorinated ethers: CF3OCF2OCF3, CF3OCF2CF2H, c-CF2CF2CF2O, CF3OCF2H, and CF3OCH3. Vapor-phase non-idealities were measured for each compound, but only for samples of high vapor density. Critical temperatures and pressures and approximate melting and boiling temperatures are reported. Apparatus calibrations were checked with measurements on the well characterized materials: CFCl3, (R11) and CF2ClH(R22). (Copyright (c) 1991, Academic Press.)
