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 (ZnCl2) has been used as an activation agent during the synthesis of phenolic based chemically activated carbon fibers (CAFs). It may also be employed as a catalyst in the preparation of carbonyl-methylene condensation products and poly(propylene fumarate).
ZnCl2 mayalso 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.
