Study on the Measurement of Viscosity and Density of Ionic Liquid for Applying It as Low Environmental-Burden Product

在293.15 ~ 353.15 K和常压下，用落球粘度计测定了[HMIM][TFSI]、[BMIM][BF 4]、[BMIM][PF 6]、[EMIM][BF 4]、[MPI][TFSI]、[PP_<13>][TFSI]、[PMIM][BF_4]、[THTDP][Cl]、[BMP][TFSI]、[BMIM][I]和[BMIM][I]十种离子液体的粘度。Marsh等人推荐[HMIM][TFSI]作为参比离子液体，并确定其粘度作为测量粘度的推荐值。该离子液体的实验粘度与这些值一致，相对偏差为。百分之零点四。Vogel-Tammann-Fulcher方程也被用来关联十种离子液体的实验粘度数据。粘度实验数据与Vogel-Tammann-Fulcher方程计算结果一致。

The viscosities of ten ionic liquids,[HMIM][TFSI], [BMIM][BF4], [BMIM][PF6], [EMIM][BF4], [MPI][TFSI], [PP_<13>][TFSI], [PMIM][BF_4], [THTDP][Cl], [BMP][TFSI], [BMIM][I], and [BMIM][I] were measured with a falling ball viscometer at 293.15 to 353.15 K and atmospheric pressure. Marsh et al. have recommended [HMIM][TFSI] as the reference ionic liquid, and determined its viscosities as recommended values for measuring viscosities. The experimental viscosities of this ionic liquid agreed with those values with a relative deviation of. 0.4%. The Vogel-Tammann-Fulcher equation was also used to correlate the experimental viscosity data of the ten ionic liquids. The experimental viscosity data were in agreement with those calculated using the Vogel-Tammann-Fulcher equation.
