| production method | 1. Chlorine gas is introduced into the secondary sublimed iodine. When the reaction is basically terminated, the reactant is heated on a water bath (not more than 75 oC), and chlorine gas is continuously introduced to conduct chlorination reaction. When the orange-yellow iodine trichloride is no longer formed, the reaction reaches the end point, and can be crushed after cooling. 2. According to the theoretical amount in the fine powder of potassium chlorate spread on a layer of crushed iodine, add a certain amount of water, so that easy to stir. A slight excess of concentrated hydrochloric acid was added in small portions with stirring, and the reaction was carried out at a temperature below 45 °c. After completion of the reaction, the reaction mixture was cooled, filtered, recrystallized from ethanol, filtered, and dried in a calcium chloride desiccator under vacuum. 3.225g of secondary sublimated iodine was placed in a weighed flask. Chlorine gas is introduced into the bottle, and sometimes the flask tremors when vented. When the reaction was nearly complete, the flask was heated on a water bath to continue the chlorination reaction. The reaction was terminated when the mass increased to 185g. The flask was broken, and the material was removed, crushed, and placed in a grinding flask. The reaction should be carried out under well-ventilated conditions. Wear a gas mask when crushing. |
