Potassium Hydroxide → 1H-Perfluorohexane

Into a 1 l four-necked flask equipped with a stirrer, a distillation apparatus-equipped refluxing condenser, a dropping funnel and a thermometer, 200 cc of methanol, 131 g of (1.1 mols) of 48% potassium hydroxide and 3 g of tetrabutylphosphonium bromide were charged. The reactor was heated to bring the internal temperature to 60° C. Then, 223 g (0.5 mol) of C6F13I was dropwise added thereto over a period of one hour. After completion of dropwise addition, heating and refluxing were continued for two hours. The conversion at that time was 97.0%. A fraction with a boiling point of up to 60° C. was recovered by distillation from the reactor. The recovered liquid was washed with 300 g of water to recover the fluorocarbon. Thus, 149 g of C6F13H having a purity of 99.9%, was obtained.
