Tetrasulfane (S4H2) is an inorganic chemical compound featuring a disulfide and two thiol groups.
Production
[edit | edit source]Similar to other polysulfanes, it can be made by neutralizing the given polysulfane salt with an acid, such as HCl or H2SO4. Example given with HCl and Na2S4:[1]
- Na2S4 + 2 HCl → 2 NaCl + H2S4
Physical properties
[edit | edit source]Same as other polysulfanes, tetrasulfane it is a yellowish, oily liquid. Its density is around 1.5 g/cm3 (±0.1 g/cm3).[2]
