Lithium chloride plus α-picolinium chloride.: A binary quasi-fragile system.

Binary melts were prepared from alpha-picolinium chloride (alpha-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 T-o 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][alpha-picH](3) complex species. Also, those values of transport and cohesive properties were compared with values of acidic 1-methyl-3-ethylimidazolium chloride, aluminium chloride and lithium chloride melt systems.
