Synthesis And Decomposition Of Platinum Tetrachloride

Platinum tetrachloride is a hygroscopic red-brown powder, easily decomposed on heating, easily soluble in water and acetone, hardly soluble in ethanol, and becomes yellow PtCl4·5H2O when it absorbs moisture in the air.

Decomposition: When heated to 370℃ in chlorine, it will be decomposed into platinum dichloride and chlorine.

Synthesis: Place chloroplatinic acid in a boat in a hard glass tube, and slowly increase the temperature from 60°C to 150°C to completely volatilize the water. Continue to heat up to 275-300°C within 2h, keep it for half an hour, and then lower the temperature to 150°C. After the product is taken out and quickly crushed, it is placed in a boat again and heated to 275°C in a stream of chlorine. Keep it warm for half an hour, and put the product into a sealed bottle while it is hot.

Uses: Direct use is to make platinum asbestos used as a catalyst, and it can also be used to make anticancer drug cisplatin, which has a special effect on ovarian cancer and testicular cancer.

Storage: Airtight at room temperature, cool, ventilated and dry.
