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...
chlorination reaction, and crude antimony trichloride produced was discharged from the bottom of the column. The crude product was distilled under reduced pressure to remove antimony pentachloride, followed by arsenic removal, cooling crystallization and pulverization to obtain finished antimony trichloride ...
