Molecular formula:C6F13I
Molecular Weight:445.95

To an autoclave (stainless steel, volume:1L) equipped with a mixing tank and a stirrer, C4F9I which compound (1) flow rate 25mL/min, CF2=CF2 (tetrafluoroethylene) which compound (2) flow rate 0.37g/min, (C2F5COO)2 (10 and half hour life temperature: 31°C) which compound (4) flow rate 0.052 mmol/min were supplied, the mixture was prepared by mixing at stirrer. Temperature in the autoclave was 10°C, residence time of the mixture in the autoclave was 10 minutes. The molar ratio (C4F9I/CF2=CF2)of C4F9I and CF2=CF2 in the mixed solution was 41, the amount of (C2F5COO)2 with respect to C4F9I was 0.034 mol%. Only the mixture from the bottom of the autoclave was withdrawn in the absence of gas phase, the mixture was fed to the bottom of tubular reactor (Tankan-shiki, volume: 0.5L). The mixture was not seperated by gas-liquid separation, the mixture was flow towards the outlet from the inlet of the reaction tube in the tube reactor. The temperature of the reaction tube, and a 70°C, the residence time of the mixture in the tubular reactor was set to 20 minutes. The mixture containing a compound Perfluoro-1-iodohexane C6F13I was obtained.

Into an autoclave 1 (made of stainless steel, capacity: 1 L) having a stirrer, C₄F₉I as the compound (1) was supplied at a flow rate of 25 mL/min, CF₂=CF₂ (tetrafluoroethylene) was supplied at a flow rate of 0.10 g/min, and (C₂F₅COO)₂ (10 hour half-life temperature: 28°C) was supplied at a flow rate of 0.0065 mmol/min, and they were mixed by the stirrer to prepare a mixed solution. The temperature in the autoclave was set to be 70°C, and the retention time of the mixed solution in the autoclave was set to be 20 minutes. The obtained reaction mixture (1) contained C₆F₁₃I as the compound (2). The amounts of tetrafluoroethylene and (C₂F₅COO)₂ were 0.65 mol% and 0.00425 mol%, respectively, to C₄F₉I.[0071] From the bottom of the autoclave 1, the reaction mixture (1) was withdrawn and supplied into an autoclave 2 (made of stainless steel, capacity: 1 L) having a stirrer, at a flow rate of 25 mL/min, CF₂=CF₂ (tetrafluoroethylene) was supplied at a flow rate of 0.10 g/min, and (C₂F₅COO)₂ (10 hour half-life temperature: 28°C) was supplied at a flow rate of 0.0065 mmol/min, and they were mixed by the stirrer to prepare a mixed solution. The temperature in the autoclave was set to be 70°C, and the retention time of the mixed solution in the autoclave was set to be 20 minutes to obtain a reaction mixture (2) containing C₆F₁₃I as the compound (2). The amounts of tetrafluoroethylene and (C₂F₅COO)₂ supplied, were 0.65 mol% and 0.00425 mol%, respectively, to the total of telomers in the mixed solution.[0072] From the bottom of the autoclave 2, the reaction mixture (2) was withdrawn, and an analysis of the composition was carried out to obtain the C₄F₉I conversion and C8+/C6 (%). The results are shown in Table 1.
