Application

Hydrosilylation Catalysts

Chloroplatinic acid hydrate may be used:
• in the determination of potassium, by selective precipitation as potassium chloroplatinate.
• in the purification of platinum.
• In catalysis during the addition of silicon hydrides to olefinic double bonds and in platinum-catalyzed hydrosilylation of alkynes.

General description

Chloroplatinic acid hydrate is the most readily available compound of platinum. It may be prepared by dissolving platinum in aqua regia. Thermogravimetric analysis of this compound has been reported. The analysis shows the loss of water followed by formation of platinum tetrachloride (PtCl4) at 220 °C and β-PtCl2 at 350 °C finally decomposing to platinum metal at 500 °C.
