Antymon - Preparation Method
Open Data Verified Data
The antimony block was added to the reactor, and chlorine gas was introduced into the reactor to conduct a chlorination reaction to obtain crude antimony trichloride. The crude antimony trichloride was placed in a distiller, the antimony pentachloride and other impurities were removed by distillation under reduced pressure, and then distilled under normal pressure. Taking 221~225 ℃ fraction, after reduction, the purity of metallic antimony is no less than 99. 999%. Using this metal antimony as raw material, after double distillation purification, the purity of high purity antimony is not less than 99. 9999%.
