生化和生理学机理:
|
Zinc chloride is a widely used as a moderate-strength Lewis acid. In biochemistry research this is used for a source of the zinc ion. It can also be used alone or with phenols for preserving railway ties, fireproofing timber, and with ammonium chloride as a flux for soldering and etching of metals.
