The study of
interactions in the trifluoroacetic acid-sulphur dioxide systems by IR
spectroscopy
Abstract
The structure of intermediates formed upon
sulphur dioxide’s oxidation by oxygen in trifluoroacetic acid of varying
concentration has been studied by multiple frustrated total internal reflection
(FTIR) IR spectroscopy at 30°C. The formation of a sulphur
dioxide-trifluoroacetic acid complex, participating in the oxygenation, has
been established for the systems that contain 99.9% and 55.5% of
trifluoroacetic acid.
