Synthesis of lead tetrachloride (tetrachloroplumbane)

Preparation of lead tetrachloride

Preparation of lead tetrachloride

Preparation of lead tetrachloride

When lead dichloride is suspended in hydrochloric acid and gaseous chlorine passed into the liquid, a solution of chloroplumbic acid is obtained, from which, on addition of ammonium chloride, a ammonium salt of chloroplumbic acid, (NH4)2PbCl6 separates. Treating this compound in cold with concentrated sulfuric acid, an energetic reaction ensues, and lead tetrachloride separates as an oily substance, which is purified by shaking with fresh quantities of sulfuric acid. In the pure state, lead tetrachloride is a translucent, yellow, highly refractive liquid which fumes in contact with moist air, with decomposition into lead dichloride and chlorine. Lead tetrachloride may be kept under cold concentrated sulfuric acid, but when heated with it, it decomposes with explosion into lead dichloride and chlorine. The sp. gr. of lead tetrachloride at 0° C. is 3.18 g/ml, and it solidifies to a yellowish crystalline mass at 15° C. Additionally it forms a hydrate in the presence of a little water, which, by the further addition of water, decomposes into lead peroxide and hydrogen chloride.
