Sulfide - Examples

Examples

Formula Melting point (°C) Boiling point (°C) CAS number
H2S Hydrogen sulfide is a very toxic and corrosive gas characterised by a typical odour of "rotten egg". -85,7 -60,20 7783-06-4
CdS Cadmium sulfide can be used in photocells. 1750 1306-23-6
Calcium polysulfide ("lime sulfur") is a traditional fungicide in gardening.
CS2 Carbon disulfide is sometimes used as a solvent in industrial chemistry. -111.6 46 75-15-0
PbS Lead sulfide is used in infra-red sensors. 1114 1314-87-0
MoS2 Molybdenum disulfide, the mineral molybdenite, is used as a catalyst to remove sulfur from fossil fuels; also as lubricant for high-temperature and high-pressure applications. 1317-33-5
Cl-CH2CH2-S-CH2CH2-Cl Sulfur mustard (mustard gas) is an organosulfide (thioether) that has been used as a chemical weapon in the First World War, the chloride on the molecule acts as a leaving group when in the presence of water and forms a thioether-alcohol and HCl. 13 - 14 217 505-60-2
Ag2S Silver sulfide is formed on silver electrical contacts operating in an atmosphere rich in hydrogen sulfide. 21548-73-2
Na2S Sodium sulfide is an important industrial chemical, used in manufacture of kraft paper, dyes, leather tanning, crude petroleum processing, treatment of heavy metal pollution, and others. 920 1180 1313-82-2
ZnS Zinc sulfide is used for lenses and other optical devices in the infrared part of the spectrum. Zinc sulfide doped with silver is used in alpha detectors while zinc sulfide with traces of copper has applications in photoluminescent strips for emergency lighting and luminous watch dials. 1185 1314-98-3
MeS Several metal sulfides are used as pigments in art, although their use has declined somewhat due to their toxicity. Sulfide pigments include cadmium, mercury, and arsenic.
C6H4S Polyphenylene sulfide is a polymer commonly called "Sulfar". Its repeating units are bonded together by sulfide (thioether) linkages. 26125-40-6
25212-74-2
SeS2 Selenium sulfide is an antifungal used in anti-dandruff preparations, such as Selsun Blue. The presence of the highly toxic selenium in healthcare and cosmetics products represents a general health and environmental concern. <100 7488-56-4
FeS2 The crystal lattice of pyrite is made of iron disulfide, in which iron is divalent and present as ferrous ion (Fe2+). 600 1317-66-4

Famous quotes containing the word examples:

    “There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.”
    —Bernard Mandeville (1670–1733)

    “Histories are more full of examples of the fidelity of dogs than of friends.”
    —Alexander Pope (1688–1744)
