ammoniumplatinicchloride - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| properties | ammonium chloroplatinate is a yellow equiaxed crystal, which is decomposed by heat and is almost insoluble in water and ethanol. Used to make platinum catalyst (platinum black, platinum asbestos). |
| use | chloroplatinic acid is mainly used in industry to prepare precious metal catalysts, precious metal electroplated layers and platinum asbestos, and can also be used to precipitate alkaloids and test potassium and ammonium plasma in analytical chemistry. However, chloroplatinic acid is easy to weather in the air, has a low melting point, and its crystal state is unstable. Its above characteristics determine that chloroplatinic acid is not conducive to storage and transportation. In fact, chloroplatinic acid mainly uses its chloroplatinic acid in use. Acid ions, so it is usually necessary to convert chloroplatinic acid into stable ammonium chloroplatinate to facilitate its storage, transportation and use. Used for diamagnetic materials or semiconductors. It is also used for platinum electroplating and preparation of sponge platinum. Used as an analytical reagent and also used in the manufacture of platinum brocade |
| Preparation method | It is obtained by the reaction of ammonium chloride and chloroplatin (hydrogen) acid. (1) dissolution of metal platinum adding 18.2 g20wt% hydrochloric acid and 71.7 g70wt% perchloric acid to 19.5g of metal platinum, introducing 3.5g chlorine gas, heating to 40 ℃, and obtaining a mixed solution after the metal platinum is completely dissolved. (2) prepare chloroplatinic acid solution heat the mixed solution to 30 ℃ and evaporate slowly to dry, then add distilled water to obtain 0.1mol/L chloroplatinic acid solution. (3) prepare ammonium chloride solution add excess ammonium chloride to distilled water, heat to 40 ℃ until the remaining ammonium chloride is no longer dissolved and filtered to obtain a hot saturated solution of ammonium chloride. (4) synthetic ammonium chloroplatinate slowly add ammonium chloride hot saturated solution at 40 ℃ to 0.1mol/L chloroplatinate solution while stirring to produce yellow ammonium chloroplatinate precipitate. continue to add ammonium chloride solution until no new precipitate is generated. filter out the precipitate, clean it twice with ammonium chloride hot saturated solution, filter it with Brinell funnel, wash it with anhydrous ethanol, and dry it at 50 ℃ in an oven to obtain ammonium chloroplatinate. the yield of ammonium chloroplatinate obtained by determination is 98.2%, and the purity of the prepared ammonium chloroplatinate is 99.1%. |
