Reaction Steps

Into a 20 l Hastelloy C autoclave equipped with a stirrer, a reflux condenser, a dropping funnel and a thermometer, 7700 g of methanol, 60 g of isopropyl alcohol and 1980 g (30 mols) of 85% potassium hydroxide were charged. The reactor was heated to bring the internal temperature to 55° C. Then, 4460 g (10 mols) of C6F13I was fed thereto over a period of two hours. While maintaining the reactor at 55° C. stirring was continued for 10 hours. The conversion was more than 99.9%. Then, 3200 g of water was added to dissolve precipitated potassium iodide. The crude reaction solution was separated into two layers, and the fluorocarbon layer (lower layer) was further washed twice with 3200 g of water to obtain 2951 g of C6F13H (purity: 99.9%, 3.9 ppm of C6F13I was detected). In the reactor, no formation of tar was observed.
