Abstract
Sulfuryl fluoride is produced by reacting a gaseous mixture of chlorine, sulfur dioxide and hydrogen fluoride, at a temperature between about 125.degree. and 400.degree. C in the presence of a catalytic amount of an alkaline earth metal fluoride.
Claims9
A process for producing sulfuryl fluoride which comprises introducing a substantially anhydrous gaseous mixture of chlorine, sulfur dioxide and hydrogen fluoride into a reaction zone in which there is present an alkaline earth metal fluoride catalyst, maintaining the temperature in the reaction zone between about 125.degree. C and 400.degree. C, and recovering the sulfuryl fluoride produced.
A process for producing sulfuryl fluoride wich comprises introducing a substantially anhydrous gaseous mixture of chlorine, sulfur dioxide and hydrogen fluoride into a reaction zone in which there is present activated carbon impregnated with barium fluoride, maintaining the temperature in the reaction zone between about 140.degree. and 190.degree. C and recovering the sulfuryl fluoride thus produced.
