| use | used in organic synthesis or as analytical reagents, solvents and fungicides. Used as solvent solvent. Organic synthesis. |
| Production method | It is obtained by the reaction of n-butanol and iodine in the presence of phosphorus. Mix red phosphorus with n-butanol, heat it to reflow slightly, and slowly add iodine. After adding, continue to reflux for 4 hours and distill to obtain crude products. Wash with water, concentrated hydrochloric acid, water, 10% sodium carbonate solution and water containing a small amount of sodium thiosulfate. Then it is dried and distilled with anhydrous calcium chloride to collect the 129-131 ℃ fraction, which is 1-iodobutane. 90% yield. |
