Nelson54 studied the products of radiolysis of aqueous solution by variable-field CIDNP pulse radiolysis. On the basis of the chemical shifts the following products were identified methyl methanesulfinate, methanol, l,2-bis(methylsulfinylethane) [CH3S(0)CH2CH2S(0)CH3], dimethyl sulfone, dimethyl sulfide, methane and ethane. The high field polarization was used to study the mechanism of formation of polarized products. 

Contact with the following materials, containing combined hydrogen, is likely to cause fire or explosion acetic acid, ammonia, benzene, ethanol, hydrogen, hydrogen sulfide, methane cork, grease, paper, wax, etc. The carbon content further contributes to the observed reactivity [1]. Chloromethane reacts with explosive violence [2]. See Acetonitrile, above... 

Rhodococcus sp. Strain T09 A Rhodococcus strain T09 was isolated by enrichment on media-containing BT. The desulfurization mechanism of this organism was reported to be similar to Gordonia sp. 213E due to the observation of similar intermediates however, the substrate specificity was different. The strain T09 could use 2-methyl, 3-methyl and 5-methyl BT apart from BT as sole source of sulfur for growth, but not 7-methyl or ethyl derivatives. Additionally, it could also use methyl thiobenzothiazole, marcaptobenzothiazole, as well as benzene sulfide, benzene sulfonate, biphenyl sulfinate, dimethyl sulfate, dimethyl sulfone, dimethyl sulfide, methane sulfonic acid, thiophene, and taurine as sole sulfur sources. However, it could not grow on DBT or DBT sulfone.

Methane forms microbiologically in strictly anaerobic conditions, but it is oxidized in both oxic and anoxic conditions [73]. The typical values for methane concentrations in the oxic layer are about 0.006-0.009 pM. The increase in methane concentration starts at erg = 15.92 kgm-3. At the onset of hydrogen sulfide, methane concentrations reach 0.350-0.500 pM. The vertical gradient of methane over the density range og = 16.20-16.40 kgm-3 is equal to 0.036-0.054 pMm-1. In the layer of a = 15.90-15.93 kgm-3 the methane...

One of the interesting features of the system hydrogen sulfide + methane is liquid-phase immiscibility. The H2S-rich and CH4-rich liquids are immiscible. However, this occurs at temperatures well below those of interest in acid gas injection. Unusual looking phase diagrams are often obtained for mixtures rich in H2S and CH4 because the algorithms typically are not designed for multiple...

For the 11 substances, ammonia, 1,2-butanediol, 1,3-butanediol, carbon monoxide, 1,1-difluoroethane, ethane, heptane, hydrogen, hydrogen sulfide, methane, and propane, the liquid heat capacity CpL is calculated with Eq. (2) below. For all other compounds, Eq. (1) is used. For benzene, fluorine, and helium, two sets of constants are given for Eq. (1) that cover different temperature ranges, as shown in the table.
