Lithium chloride + α-picolinium chloride. A binary quasi-fragile system

Binary melts were prepared from a-picolinium chloride (α-PicHCl) and lithium chloride. Densities, electrical conductivities, viscosities and glass transition temperatures were determined. Transport properties data were studied by VTF equation and fragility concept applied. Both, T_g data and T₀ parameters indicate the existence of a broad maximum around X(LiCl) = 0.25 due to a low value of configurational entropy. Viscosity and electrical conductivity support the formation of [LiCl₄][α-picH]₃ complex species. Also, those values of transport and cohesive properties were compared with values of acidic l-methyl-3-ethylimidazolium chloride, aluminium chloride and lithium chloride melt systems.
