Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethanol | HCID 702 | — |
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | Trifluoroacetic acid | HCID 6422 | — |
| Solvent | Water | HCID 962 | — |
| Product | Ethyl trifluoroacetate | HCID 9794 | — |
Reaction Steps
in a first stage, trifluoroacetic acid is brought into contact with a slight excess of ethanol in the presence of concentrated sulfuric acid and a solvent, the solvent having a boiling point higher than that of trifluoroacetic acid and specific gravity relative to water less than 1 and which solvent does not form an azeotrope with ethyl trifluoroacetate, and then carrying out a phase separation and removing the sulfuric layer, followed, if required, by an additional stage in which concentrated sulfuric acid is added to complete the esterification;
