The purpose of this study was to determine the kinetics of the mass transfer reaction kinetics of the chemical absorption of sulfuryl fluoride in sodium hydroxide solution and to establish an enhancement factor model. Research Methods: The process of chemical absorption of sulfuryl fluoride in sodium hydroxide solution in the double-stirred tank of gas-liquid mass spectrometry was studied. The enhancement factor model was established by combining experimental and theoretical analysis. Important conclusions: Based on the experimental study on the chemical absorption of sulfuryl fluoride by sodium hydroxide solution, it was confirmed that the mass transfer reaction kinetics of the chemical absorption of sulfuryl fluoride by sodium hydroxide solution is a fast quasi-first-order reaction. The second-order reaction rate constant of 1.44 m3 / (mol · s) at 298 K was obtained, and the enhancement factor model E = 68.08CBL1 / 2 was established, which provided a theoretical basis for the industrialized application of residual sulfuryl fluoride after fumigation .
