|Section2= |Section3= |Section4= }} Disulfur is the diatomic molecule with the formula S2. It is analogous to the dioxygen molecule but rarely occurs at room temperature. This violet gas is commonly generated by heating sulfur above 720 °C and comprises 99% of the vapor at low pressure (1 mm Hg) at 530 °C. S2 is one of the minor components of the atmosphere of Io, which is predominantly composed of SO2. Diatomic molecules are common containing C, O, N, and F, but for heavier elements they are often only stable at high temperatures. ==Production== Disulfur results when an atmosphere of COS is irradiated with UV light using a mercury photosensitizer or when CS2, H2S2, S2Cl2 or C2H4S are photolyzed. Singlet S2 is also formed when sulfur compounds such as H2S, PSF3 or COS are photolyzed. S2 can be generated by heating various organosulfur precursors. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「disulfur」の詳細全文を読む スポンサード リンク
