Abstract: A method for preparing sulfuryl fluoride by electrofluorination is described. The method for preparing sulfuryl fluoride by electrofluorination comprises a step of subjecting sulfur dioxide and a hydrogen fluoride complex to an electrofluorination reaction in an electrolytic cell. By means of this, the production cost of sulfuryl fluoride can be reduced, and the purity and yield of sulfuryl fluoride can be improved, thus making it suitable for industrial production.
