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.确定氢氧化钠溶液化学吸收硫酰氟的传质反应动力学区域, 建立增强因子模型。研究气液传质测定设备双搅拌釜中氢氧化钠溶液化学吸收硫酰氟的过程, 并结合实验研究与理论分析建立了增强因子模型。基于氢氧化钠溶液化学吸收硫酰氟过程的实验研究, 确定了氢氧化钠溶液化学吸收硫酰氟的传质反应动力学区域为快速拟一级反应。得到了298 K 下其二级反应速率常数为1.44 m$^{3}$/(mol·s), 并建立了增强因子模型E=68.08C $_{BL}$ $^{1/2}$, 为脱除熏蒸后残留硫酰氟的工业化应用提供了理论依据。
