'''Antimony pentasulfide''' is an [[inorganic compound]] of [[antimony]] and [[sulfur]], also known as '''antimony red'''. |
'''Antimony pentasulfide''' is an [[inorganic compound]] of [[antimony]] and [[sulfur]], also known as '''antimony red'''. It is a [[nonstoichiometric compound]] with a variable composition. Commercial samples are contaminated with sulfur, which may be removed by washing with [[carbon disulfide]] in a [[Soxhlet extractor]]. |
||
==Production== |
|||
Antimony pentasulfide can be produced by the reaction of antimony with sulfur at a temperature from 250 to 400 °C in an inert atmosphere. |
|||
==Uses== |
|||
It may be used as a red [[pigment]] and is one possible precursor to [[Schlippe's Salt|Schlippe's salt]], {{chem2|Na3SbS4*9H2O}}, which can be prepared according to the equation: |
|||
:{{chem2|3 Na2S + Sb2S5 + 9 H2O → 2 Na3SbS4*9H2O}} |
|||
It is also used in the [[vulcanization]] of [[rubber]] to produce red rubber. |
|||
==Physical chemistry== |
|||
Like many [[sulfide]]s, this compound liberates [[hydrogen sulfide]] upon treatment with [[strong acid]]s such as [[hydrochloric acid]].<ref>[http://www.strem.com/catalog/printer.php?type=msds&catalog_number=93-5105 Strem MSDS]</ref> |
|||
:{{chem2|6 HCl + Sb2S5 → 2 SbCl3 + 3 H2S + 2 S}} |
|||
Analysis by [[Mössbauer spectroscopy]] indicates that this compound is a derivative antimony(III)<ref>{{cite journal | title = The oxidation number of antimony in antimony pentasulfide | journal = Inorganic and Nuclear Chemistry Letters | volume = 5 | issue = 1 | year = 1969 | pages = 21–25 |=G. G. Long J. G. Stevens L. H. Bowen S. L. Ruby | doi = 10.1016/0020-1650(69)80231-X}}</ref> It is therefore not analogous to [[phosphorus pentasulfide]]. |
