Properties and stability

1. Discoloration when exposed to light or left for a long time. It is flammable and may cause combustion and explosion hazards when exposed to open flames, high heat, or oxidants. It decomposes when heated to release toxic iodide vapor. It is prone to nucleophilic substitution reactions; it can be reduced to butane by concentrated hydrogen iodide; it can generate octane through Wurtz reaction; it can generate butene by azeotrope with potassium hydroxide alcohol solution.

2. Stability[13] Stable

3. Incompatible substances[14] Strong oxidizing agent, strong alkali

4. Polymerization hazard[15] No polymerization

5. Decomposition products[16] Hydrogen iodide

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 30℃. Keep container tightly sealed. They should be stored separately from oxidants and acids, 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-butanol and iodine in the presence of phosphorus. Mix red phosphorus and n-butanol, heat to slightly reflux, and slowly add iodine. After the addition, continue to reflux for 4 hours and distill to obtain crude product. Wash with water, concentrated hydrochloric acid, water, 10% sodium carbonate solution and a small amount of sodium thiosulfate and water in sequence. Then dry with anhydrous calcium chloride, distill, and collect the 129-131°C fraction, which is 1-iodobutane. The yield is 90%.

Purpose

1. Used as analytical reagents, solvents, and organic synthesis. [18]
