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.

Storage and Stability

1. Hygroscopic material, always handle in a glove bag or a glove box filled with dry inert gas2. Recommended for one time use to prevent water absorption and degradation. If necessary, once opened, repack and seal under dry inert gas. 3. Store with care. Prevent from light. Always store in well-sealed containers in a dry inert atmosphere. Recommended to store containers in a secondary desiccator with desiccant in a dry inert atmosphere.
