History of SF6Chemical Properties of SF6 GasElectrical Properties of SF6 GasSF6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that SF6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very r...See more on electrical4u.comSulfur monochloride | S2Cl2 - PubChem › compound › Sulfur-monochlorideIn the batch process, chlorine is passed into a solution of sulfur in S2Cl2 with cooling at about 50 - 70 &C until the correct chlorine content is reached. In the continuous process, gaseous chlorine is passed into molten sulfur at 220 - 260 &C, and the gaseous S2Cl2 leaving the reactor is then condensed.
