The compound (C 5 H 5) 2 TiS 5 is an example of a polysulfide complex. Polysulfides are a class of chemical compounds derived from anionic chains of sulfur atoms. [1] There are two main classes of polysulfides: inorganic and organic. The inorganic polysulfides have the general formula S 2− n. These anions are the conjugate bases of ...
Sodium polysulfide is a general term for salts with the formula Na 2 S x, where x = 2 to 5. The species S x 2−, called polysulfide anions, include disulfide (S 2 2−), trisulfide (S 3 2−), tetrasulfide (S 4 2−), and pentasulfide (S 5 2−). In principle, but not in practice, the chain lengths could be longer.
Liver of sulfur is a loosely defined mixture of potassium sulfide, potassium polysulfide, potassium thiosulfate, and likely potassium bisulfide. Synonyms include hepar sulfuris, sulfur, sulfurated potash and sulfurated potassa. There are two distinct varieties: "potassic liver of sulfur" and "ammoniacal liver of sulfur". [1]
Chemical formula. K 2 S 5 Molar mass: 238.50 g·mol −1 ... It is one of several polysulfide salts with the general formula M 2 S n, where M = Li, Na, K and n = 2, 3 ...
In horticulture, lime sulfur (lime sulphur in British English, see American and British English spelling differences) is mainly a mixture of calcium polysulfides and thiosulfate [1] (plus other reaction by-products as sulfite and sulfate) formed by reacting calcium hydroxide with elemental sulfur, used in pest control.
Thiokol is a trade mark for various organic polysulfide polymers. [1] Thiokol polymers are used as an elastomer in seals and sealants.The distinction between the polymers first commercialized by the Thiokol Chemical Company and subsequent polysulfide materials is often unclear.
Sulfur mustard (mustard gas) is an organosulfur compound (thioether) that was used as a chemical weapon in the First World War. 13–14: 217: 505-60-2: Ag 2 S: Silver sulfide is a component of silver tarnish. 21548-73-2: Na 2 S: Sodium sulfide, as the hydrate, is used in manufacture of kraft paper and as a precursor to organosulfur compounds ...
On the other hand, the poly (sulfur-random-1,3-diisopropenylbenzene) acts as thermoplastic at 15–25%wt of DIB, while it becomes a thermoplastic-thermosetting polymer for a diene concentration of 30-35%wt. [16] The potential to break and reform the chemical bonds along the polysulfide chains (S-S) allows the repair of the copolymer by simply ...
