Abstract: The mass transfer and reaction kinetics of sulfuryl fluoride (SO₂F₂) absorption with aqueous sodium hydroxide (NaOH) solutions were studied in an experimental double-stirred cell. Results showed that SO₂F₂ absorption with NaOH was followed by a reaction model employing a fast pseudo-first-order. The second-order rate constant for SO₂F₂ absorption with aqueous NaOH solutions was determined to be 1.44 m³/(mol·s) at 298 K. Three models were used in this chemical absorption process, and in each case, the same expression of enhancement factor was obtained. A comparison was made between the experimental enhancement factor and the value calculated from the model, and the maximum relative deviation was less than 4.2%. The proposed model expression gave a reasonable fit with the experimental values, indicating that mass transfer correlations are valid for scaling up design.
