Description

General description

Zinc chloride is a zinc salt. Zinc chloride in combination with 1-ethyl-3-methylimidazolium chloride comprises a molten salt, which is employed in the electrodeposition studies of zinc.
Zinc chloride is a colorless white compound composed of zinc and chlorine, which can be used as a flux for soldering.

Application

Zinc chloride may be employed as catalyst in Knoevenagel condensation of carbonyl compounds with active methylene group containing reagents. It may be used in preparation of porous carbon nanofibers, useful in the fabrication of efficient electrodes for supercapacitors. It may be used as catalyst in the preparation of poly(propylene fumarate).
