FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. The method of recycling carbon dioxide involves feeding carbon dioxide through at least one vessel filled with trifluoroacetic acid saturated with oxygen. The formed product is separated and spent acid is regenerated by saturating with oxygen and recycling the saturated acid into the process. Carbon dioxide is preferably fed at temperature 10-25°C and atmospheric pressure.
EFFECT: method increases efficiency of recycling carbon dioxide, enables to carry out the recycling process at room temperature and atmospheric pressure, and the recycling product can be used as an octane-increasing additive for engine fuel.
