Mass transfer and reaction kinetics of sulfuryl fluoride absorption with aqueous sodium hydroxide solutions

Abstract

Abstract:The mass transfer and reaction kinetics of sulfuryl fluoride (SO 2 F 2 ) absorption with aqueous sodium hydroxide (NaOH) solutions were studied in an experimental double-stirred cell. Results showed that SO 2 F 2 absorption with NaOH was followed by a reaction model employing a fast pseudo-first-order. The second-order rate constant for SO 2 F 2 absorption with aqueous NaOH solutions was determined to be 1.44 m 3 /(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.

“…Ravindar et al 10 studied application of sulfuryl fluoride in chemical transformations, and they pointed out chemical transformations using the readily available feedstock sulfuryl fluoride. Nie et al 11 studied mass transfer and the reaction kinetics of sulfuryl fluoride absorption with aqueous sodium hydroxide solutions. The results showed that the second-order reaction rate constant at 298 K is 1.44 m 3 (mol/s), and the enhancement factor model E = 68.08 mol/L was established.…”
