New ionic liquids based on the complexation of dipropyl sulfide and AlCl3 for electrodeposition of aluminum

Abstract

A new kind of ionic liquid based on the complexation of dipropyl sulfide (DPS) and AlCl₃ has been prepared. The equivalent concentration of AlCl₃ in the ionic liquid is as high as 2.3 M. More importantly, it is highly fluidic and exhibits an ambient ionic conductivity of 1.25 × 10⁻⁴ S cm⁻¹. This new ionic liquid can be successfully used as an electrolyte for electrodeposition of aluminum.
