General description

Zinc chloride in combination with 1-ethyl-3-methylimidazolium chloride comprises a molten salt, which is employed in the electrodeposition studies of zinc on various substrates (glassy carbon and nickel).

Application

Zinc chloride may be used as a catalyst for the Knoevenagel condensation of aromatic aldehydes with substituted acetonitriles to form carbonyl-methylene products under solvent-free conditions. The activation of sugar cane bagasse with zinc chloride forms activated carbons for use as supercapacitor electrodes.
ZnCl2 may be employed as a catalyst in the preparation of carbonyl-methylene condensation products and poly(propylene fumarate).
