Transport Numbers in Molten Aluminum Chloride‐1‐Methyl‐3‐Ethylimidazolium Chloride Mixtures

Abstract

The transport numbers of 1‐methyl‐3‐ethylimidazolium (MEI+), , and Cl− ions were measured in equimolar and melts of and 1‐methyl‐3‐ethylimidazolium chloride (MEICl). The moving boundary method and a modified Hittorf method were used. The external transport numbers of the three ions in the equimolar melt were , , and 0, respectively. As mole fraction decreases, the transport number for decreases, while that for Cl+ increases and that for MEI+ remains the same. The internal transport number of the MEI+ relative to Cl as the reference is .
