Photolysis of Dimethyl Disulfide

Title Some Observations on the Photolysis of Dimethyl Disulfide

Surface Chemistry and Extreme-Pressure Lubricant Properties of Dimethyl Disulfide

The growth kinetics of a film formed by the thermal decomposition of dimethyl disulfide on an iron foil are measured using a microbalance where the growth kinetics are parabolic (film thickness X varies with time as X2 ∝ t) at high reaction temperatures and pressures, indicating that it is limited by diffusion through the film. The activation energy for this process is 54.5 ( 0.5 kcal/mol. The ...

Bis(4,6-diamino­pyrimidin-2-yl) disulfide dimethyl sufoxide disolvate

The title compound, C(8)H(10)N(8)S(2)·2C(2)H(6)SO, was obtained unintentionally during an attempt to prepare a thiol-ate derivative of trimethyl-tin. The complete disulfide mol-ecule is generated by twofold rotation symmetry and the C-S-S-C torsion angle around the S-S bond is -85.70 (10)°. The mol-ecules are connected via N-H⋯N hydrogen bonds into strongly corrugated layers parallel to (001), ...

Dimethyl disulfide (DMDS) and dimethyl sulfide (DMS) emissions from biomass burning in Australia

[1] We identify dimethyl disulfide (DMDS) as the major reduced sulfur-containing gas emitted from bushfires in Australia’s Northern Territory. Like dimethyl sulfide (DMS), DMDS is oxidized in the atmosphere to sulfur dioxide (SO2) and methane sulfonic acid (MSA), which are intermediates in the formation of sulfuric acid (H2SO4). The mixing ratios of DMDS and DMS were the highest we have ever de...

Mercury(II) ion detection via pyrene-mediated photolysis of disulfide bonds.

Contamination of the environment with heavy metal ions has created a pressing public health concern in living systems. Mercury is widely considered to be one of the most hazardous pollutants and highly dangerous elements due to its recognized accumulative and toxic characters in the environment and the ecosystem. The sources of mercury pollution mainly include coal-fired power plants, oceanic a...
