Tóm tắt

Experimental data of densities and viscosities are presented for the system 4-methyl-N-butylpyridinium tetrafluoroborate + methanol at 25, 40, and 50, 323.15 K and ambient pressure using a vibratage-tube densimeter and an Ubbelohde viscometer. Excess molar volumes V E and excess logarithm viscosities (ln η)E have been determined. V E is negative and (ln η)E positive over the entire mixture composition.
