Abstract

The pyrolysis of perfluoro(2,4-dimethyl-3,6-dioxa-8-fluorosulfonyloctanoyl fluoride)(I) in the presence of Na2CO3 in a solvent was studied. The reaction took place in two steps, i.e. first, I reacted with sodium carbonate at a temperature of 60 癈 to form the sodium carboxylate, which was then decarboxylated at a temperature of 180-220 癈. The various reaction byproducts were separated and identified, and the reaction mechanism was studied.

Key words: SOLVENTS, SODIUM COMPOUNDS, SULFONE, REACTION MECHANISM, INFRARED SPECTROPHOTOMETRY, GAS CHROMATOGRAPHY, NMR SPECTROMETRY, SODIUM CARBONATE, OCTANE P, ACYL FLUORIDES
