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 the dropwise addition, heating and refluxing were continued for 6 hours. The conversion was more than 99.9%. The reactor was cooled to room temperature, and then, 300 g of water was added to dissolve precipitated sodium iodide. The crude reaction solution was separated into two layers, and the fluorocarbon layer (lower layer) was further washed twice with 300 g of water to obtain 145 g (purity: 99.9%) of C6F13H. In the reactor, no formation of tar was observed.
