Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO 2, SO 3, S 7 O 2, S 6 O 2, S 2 O 2, etc. Sulfur oxide (SO x) refers to one or more of the following: Lower sulfur oxides (S n O, S 7 O 2 and S 6 O 2) Sulfur monoxide (SO) and its dimer, Disulfur dioxide (S 2 O 2) Sulfur dioxide (SO 2) Sulfur trioxide (SO 3)
The SO molecule has a triplet ground state similar to O 2 and S 2, that is, each molecule has two unpaired electrons. [2] The S−O bond length of 148.1 pm is similar to that found in lower sulfur oxides (e.g. S 8 O, S−O = 148 pm) but is longer than the S−O bond in gaseous S 2 O (146 pm), SO 2 (143.1 pm) and SO 3 (142 pm).
Disulfur dioxide, dimeric sulfur monoxide or SO dimer is an oxide of sulfur with the formula S 2 O 2. [2] The solid is unstable with a lifetime of a few seconds at room temperature. [ 3 ]
SO 2 + Cl 2 → SO 2 Cl 2. Sulfur dioxide is the oxidising agent in the Claus process, which is conducted on a large scale in oil refineries. Here, sulfur dioxide is reduced by hydrogen sulfide to give elemental sulfur: SO 2 + 2 H 2 S → 3 S + 2 H 2 O. The sequential oxidation of sulfur dioxide followed by its hydration is used in the ...
Sulfur poisoning arises when fuel such as natural gas, gasoline, or diesel is used. Again, due to the high affinity between sulfur compounds (H 2 S, (CH 3) 2 S) and the metal catalyst, even the smallest impurities of sulfur compounds in the feed stream could deactivate the Ni catalyst on the YSZ surface.

Sulfur monoxide (SO) and its dimer (S 2 O 2) have been trapped at low temperature. Disulfur dioxide (S 2 O 2) is a dimer of sulfur monoxide. It has C 2v structure (planar). Disulfur monoxide (S 2 O) is an analogue of sulfur dioxide. Like SO 2 as well as ozone (O 3), and trisulfur (S 3), it adopts a bent structure. The S-S bond length is 188.4 ...
Sulfur polycations, S 8 2+, S 4 2+ and S 16 2+ are produced when sulfur is reacted with oxidising agents in a strongly acidic solution. [1] The colored solutions produced by dissolving sulfur in oleum were first reported as early as 1804 by C.F. Bucholz, but the cause of the color and the structure of the polycations involved was only ...
Disulfur monoxide or sulfur suboxide is an inorganic compound with the formula S 2 O, one of the lower sulfur oxides. It is a colourless gas and condenses to give a roughly dark red coloured solid that is unstable at room temperature. S 2 O occurs rarely in natural atmospheres, but can be made by a variety of laboratory procedures. For this ...
