Safety Profile

Mutation data reported. Human systemic effects by intradermal route: dermatitis. When heated to decomposition it emits toxic fumes of K2O and Cl-. Used as a catalyst for carbonylation of alkynes. See also PLATINUM COMPOUNDS.

Purification Methods

It crystallises from water (20mL/g) between 100o and 0o. Its solubility in H2O is 0.7% at 0o, 1.12% at 20o, 2.16% at 50o and 5.13% at 100o. [Grube in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1571 1965.]

General Description

Potassium hexachloroplatinate (K2PtCl6) is a source material for the preparation of platinum based compounds. It can be used in the preparation of platinum colloids by its reduction in an aqueous solution.
