摘要: A product mixture resulting from the reaction of an anhydrous gaseous mixture of sulfur dioxide, chlorine and hydrogen fluoride in the presence of a catalyst is heated at a temperature of at least about 35.degree. C. under pressures up to about 65 psi to effect substantial conversion of undesired free chlorine in the resulting product mixture to sulfuryl chlorofluoride. The conversion of free chlorine to sulfuryl chlorofluoride allows the use of a completely anhydrous process from which uncontaminated sulfuryl fluoride and sulfuryl chlorofluoride products can readily be obtained. A method for the production of sulfuryl chlorofluoride from said gaseous mixture is also provided.
