ABSTRACT
The densities, viscosities, and electrical conductivities of the ionic liquid N-methoxymethyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)amide, [Pyr1,1O1][Tf2N] have measured with expanded uncertainties of +-0.00005 g cm-3, +-2%, and +-2% over a wide temperature range between 0 and 90 oC at atmospheric pressure. The temperature dependence of the viscosity and conductivity was analyzed by the Litovitz and Vogel-Fulcher-Tammann equations. The effect of the methoxymethyl group instead of the propyl one on such physicochemical properties is discussed in comparison with the similar analogue, N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl)amide, [Pyr1,3][Tf2N].
