摘要

Although the Swedish chemist Scheele prepared chlorine in 1774 by the action of hydrochloric acid on manganese dioxide, the gas was believed to be a compound until 1810 when Humphry Davy gave convincing proof of its elementary nature. The background of the discovery and the reason for the delayed recognition of the nature of chlorine is outlined. In spite of that, the gas was immediately put into useful applications. The first application in metallurgy was the laboratory preparation of anhydrous aluminium chloride by the Danish scientist Hans Christian Oersted in 1825, which led to a commercial scale production of the first metallic aluminium in 1854 by the French chemist Henri Sainte Claire Deville. It was also during this period that chlorine water was first used in hydrometallurgy for the recovery of gold by the German metallurgist Karl Plattner.
