Storage method
1. Packed in 25~500ml glass bottles and protected by wooden boxes or cartons. Store in a cool, dry and ventilated warehouse, away from fire, heat sources and protected from light. Do not mix with edible chemical raw materials.
2. Storage precautions [20] Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Avoid light. The packaging must be sealed and must not come into contact with air. They should be stored separately from oxidants, alkalis, and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
1. Obtained from the reaction of ethanol and phosphorus triiodide. Put industrial ethanol and red phosphorus into the reaction bottle, heat to reflux on a water bath, and slowly add iodine granules. After the addition is completed, continue refluxing for 3 hours. The reaction solution is then distilled to evaporate the yellow crude product, which is washed and dried to obtain the finished product. In addition, ethyl iodide can also be produced by the addition of ethylene and hydrogen iodide. The reaction formula is:
2. It is produced by the addition reaction of ethylene and hydriodic acid.
3. From ethanol and triiodine Derived from the reaction of phosphorus. The operation process is as follows: place ethanol and red phosphorus in a reaction bottle, heat and reflux on a water bath, slowly add iodine particles, and continue to reflux. Then the reaction liquid is evaporated to obtain a yellow crude product, which is then washed, dried and filtered to obtain the finished product.
