| Abstract: | Taking a boiling flask-3-neck as the reactor, Ferrous chloride is synthesized by iron powder and dilute hydrochloric acid to determine the optimal reaction condition as hydrochloric acid concentration （quantity） 18%（1 ： 1）; temperature 85 ℃; the ratio between the hydrochloride and iron powder 1.4 ： 1 ; reaction time 20 minutes. Then adding dilute hydrochloric acid, ferric chloride is oxidized to ferric chloride under acidic condition with hydrogen peroxide to fix the optimal condition as stirring speed 20, ratio between the hydrogen peroxide and iron powder 1.63 ： 1, temperature 55 ℃ and the adding rate of hydrogen peroxide 0.5 - 1.0 mL/min. |
