Na 2 S 4 + 2 ClC 3 H 6 Si(OEt) 3 → S 4 [C 3 H 6 Si(OEt) 3] 2 + 2 NaCl Bis(triethoxysilylpropyl)tetrasulfide is a bifunctional molecule in that it contains two kinds of reactive functional groups . The tetrasulfide group is a polysulfide , which means that it consists of a chain of sulfur atoms.
[4] The energy released in the reaction of sodium and elemental sulfur is the basis of battery technology. The sodium–sulfur battery and the lithium–sulfur battery require high temperatures to maintain liquid polysulfide and Na + -conductive membranes that are unreactive toward sodium, sulfur, and sodium sulfide.
