SYNTHESIS OF BROME-PROMOTED SULPHUR FLUORIDE COMPOUNDS Russian patent published in 2014 - IPC C01B17/45 C01B9/08 

FIELD: chemistry.

SUBSTANCE: SF₄, SF₅Cl, SF₅Br and SF₆ are obtained. To obtain SF₄ or compound, obtained with its application, with output higher than 10%, mixed are: Br₂, metal fluoride and sulfur-containing reagent, or Br₂, metal fluoride and sulfur-containing reagent and Cl₂ -reagent. To obtain SF₅Cl or compound, obtained with SF₅Cl application, with output higher than about 50%, mixed are: Cl₂ -reagent, sulfur-containing reagent, metal fluoride and Br₂-reagent. To obtain SF₅Br, or compound, obtained with SF₅Br application, with output higher than about 50%, mixed are: Br₂-reagent, sulfur-containing reagent and metal fluoride. To obtain SF₆ or compound, obtained with SF₆ application, with output higher than about 50%, mixed are: Br₂-reagent, SF₄-reagent and metal fluoride.

EFFECT: invention makes it possible to reduce process time, avoid production of harmful wastes.
