The Methyl Ethers of D-Galactose
1951Publisher Summary This chapter discusses methyl ethers of D -galactose. The 2,3,4,6-tetramethyl- D -galactopyranos is obtained by the full methylation of the methyl α- or β- D -galactopyranosides, followed by acid hydrolysis of the products.

Relative Permittivity Measurements of Trifluoromethyl Methyl Ether and Pentafluoroethyl Methyl Ether
Journal of Chemical & Engineering Data, 2007The relative permittivities (er) of trifluoromethyl methyl ether (HFE 143a) and pentafluoroethyl methyl ether (HFE 245mc) were measured as a function of temperature and pressure: (303 to 383) K and (1.5 to 31.6) MPa for HFE 143a and (313 to 323) K and (1.5 to 28.4) MPa for HFE 245mc.

PVT properties are presented for both the gas-phase and liquid-phase, vapor pressures and saturated-liquid densities for hydrofluoroether (HFE) refrigerants, trifluoromethyl methyl ether (CF3OCH3) and pentafluoroethyl methyl ether (C2F5OCH3), that were obtained with a Burnett apparatus and a vibrating-tube densimeter.
