Successive fluorination of dimethyl carbonate (DMC) exerts a polar effect on various fundamental properties. We describe the temperature dependence of the mass density (ρ), refractive index (nD), relative permittivity (εr), dynamic viscosity (η), and kinematic viscosity (ν) of trifluorinated, difluorinated, and monofluorinated DMCs (TFDMC, DFDMC, and MFDMC, respectively). η decreased in essentially the same order as εr: DFDMC > TFDMC > MFDMC > DMC. However, ν and the boiling point of the TFDMC were lower than those of the MFDMC.
碳酸二甲酯(DMC)的连续氟化会对各种基本特性产生极性影响。我们描述了三氟化、二氟化和单氟化 DMC(分别为 TFDMC、DFDMC 和 MFDMC)的质量密度(ρ)、折射率(nD)、相对介电常数(εr)、动态粘度(η)和运动粘度(ν)的温度依赖性。η的下降顺序与 εr 基本相同:DFDMC > TFDMC > MFDMC > DMC。不过,TFDMC 的 ν 和沸点低于 MFDMC。
