2H-Perfluoro-5-methyl-3,6-dioxanonane

反応条件: temp:120.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: The formed product obtained in Example 2-2 (42.0 g) was charged into a 200 cc autoclave together with KF powder (0.5 g) and CF3CFHOCF2CF(CF3)OCF2CF2CF3 and heated in a sealed state at from 80 to 120° C. for 13 hours and 120° C. for 14 hours in an oil bath, while vigorously stirring. At the outlet of the autoclave, a pressure resistant container cooled to −78° C. was installed, and when the internal pressure of the reactor became at least 0.28 MPa, the gas in the reactor was liquefied and recovered. 0.8 g of a sample was recovered. The recovered sample was gaseous at room temperature, and as a result of the analysis by GC-MS, the above-identified compound was confirmed to be the main product. The yield of the above-identified compound was 9.4%. At the outlet of the autoclave, a pressure resistant container cooled to −78° C. recovered 0.8 g of a sample was recovered was gaseous at room temperature as a result of the analysis by GC-MS
