Process for the preparation of ethionic acid |
| abstract |
Ethionic acid is prepared by reacting sulphur trioxide with ethanol at 40-100 DEG C., using ethionic acid as the reaction medium. The sulphur trioxide may be pure or admixed with inert gases, e.g. in the form of gas from a contact plant for sulphuric acid manufacture. Batch and continuous methods are described. |
