Storage method
Storage Precautions[17] Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. Avoid light. The storage temperature should not exceed 37°C. Keep container tightly sealed. They should be stored separately from oxidants and alkalis, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
Obtained from the reaction of n-propanol and phosphorus triiodide. First mix red phosphorus and n-propanol, heat to 80°C on a water bath, then add iodine tablets, maintain the temperature at 85-95°C, and react for 2 hours. After fractionation, the crude product is obtained, and then washed; after drying, fractionation is carried out, and the 102-103.5°C fraction is collected to obtain 1-iodopropane.
Purpose
1. Laboratory reagents. [18]
