Production methods
Derived from n-butanol and iodine reaction in the presence of phosphorus. Red phosphorus with n-butanol mixture, heating it slightly back, slowly joined iodine. Increase after returning to 4h, distillation, the crude product. Followed by water, concentrated hydrochloric acid, water, 10% sodium carbonate solution containing a small amount of sodium thiosulfate and water washing. And then dried over anhydrous calcium chloride, distillation, collecting 129-131 ° C in distillate is 1 – iodine butane. The yield of 90%.
