byproducts: SF6, SF4, SSF2; sepd. S8 and F2 in a high vac. app., cooling the fluorine to -196°C, pressure 5 atm, heating the S8 to 200°C, addn. of fluorine until the product dosn't become hot; condensation, cooling to -78°C, evapn. of volatile compds. for 0.5 h, detected by IR;

byproducts: SSF2; the sepd. fluorine and COS in a high vac. app., cooling to -196°C and -78°C, resp., after the react. cooling the gas to -196°C, further byproducts; continuous evapn. of CO; condensation, cooling to -78°C, evapn. of volatile compds. for 0.5 h, detected by IR;
