Abstract

PURPOSE: To inexpensively manufacture sulfur tetrafluoride of high purity in a high yield by reacting a pyridine compound of hydrofluoric acid having a specified composition with sulfur dichloride and circulating a compound obtd. by reacting a by- product pyridine compound of hydrochloric acid with hydrofluoric acid.
CONSTITUTION: A pyridine compound of hydrofluoric acid represented by Py(HF)n (n is 1W4) is reacted with sulfur dichloride in the presence of a mixed solvent of methylene chloride and trichlorotrifluoroethane or the like to form sulfur tetrafluoride. A by-product pyridine compound of hydrochloric acid is then reacted with a sufficient amount of hydrofluoric acid to eliminate the hydrochloric acid. This reaction product is distilled under reduced pressure to eliminate hydrofluoric acid until Py(HF)1W4 is prepared, and the resulting Py(HF)1W4 is circulated to the reaction with sulfur dichloride.
