Chemical formula PtCl4, molecular weight 336.9. Brown-red crystal, density 4.303g /

Platinum tetrachloride

Platinum tetrachloride

cm3.37 C decomposition of platinum dichloride and chlorine. Hygroscopic. Soluble in water, slightly soluble in ethanol. Dissolved in hydrochloric acid to generate chloroplatinic acid (chloroplatinic acid). Crystals containing 5 crystals of water are obtained when precipitated from an aqueous solution. The crystals are red crystals and have a density of 2.43 g / cm3. Used as analytical reagent, catalyst. By chloroplatinic acid (hydrogen) acid heating in the chlorine flow and prepared. [1]

Molecular formula: PtCl4; brown red crystal. Density 4.303g / cm3. Soluble in hot water, soluble in cold water, acetone, slightly soluble in ethanol, ammonia. Insoluble in ether. Yi Chao solution. Heating to 370 C in chlorine decomposes into platinum dichloride and chlorine. Placed in a hard glass tube by chloroplatinic acid in the boat, the temperature was slowly raised from 60 to 150 , so that the water completely volatile. Within 2h continue to heat up to 275 ~ 300 , holding half an hour, then cooled to 150 . Remove the product quickly crushed, re-placed in the boat, in a stream of chlorine heated to 275 . Insulation for half an hour, hot products will be put into sealed bottle system. For plating. Used as a catalyst and analysis reagent. Also used in the production of semiconductor epitaxy, diffusion processes. [2]
