PURPOSE: To obtain the titled compound economically, by reacting iodine and iodine pentafluoride with a fluoroolefin using antimony, molybdenum, tungsten, phosphorus or their compound as a catalyst, and a specific titled compound as a diluent.
CONSTITUTION: A perfluoroalkyl iodide is produced by the reaction of iodine, iodine pentafluoride and a fluoroolefin. The reaction is carried out by using antimony, molybdenum, tungsten, phosphorus or their compound as a catalyst, and a proper amount of a perfluoroalkyl iodide of formula CF3CF2(CF2)mI(m is 2W9) and/or (CF3)2CF(CF2)nI(n is 2, 4, 6 or 8) as a diluent. The amount of the diluent is preferably about 0.3W5 times weight of the iodine pentafluoride. The reaction heat can be removed safely and effectively by this process, and the objective compound is produced under atmospheric pressure or a relatively low pressure without necessitating the preheating of the reaction system at a high temperature.
