Sulfur organic compounds with

This gas is also produced by heating sulfur with solid organic compounds and by reducing sulfurated organic compounds with hydrogen. 

Many reactions can be carried out between potassium cyanide and organic compounds with the alkalinity of the KCN acting as a catalyst these reactions are analogous to reactions of sodium cyanide. The reactions of potassium cyanide with sulfur and sulfur compounds are also analogous to those of sodium cyanide. Potassium cyanide is reduced to potassium metal and carbon by heating it out of contact with air in the presence of powdered magnesium. Magnesium is converted to the nitride ...

Volatile organic compounds (VOCs) include organic compounds with appreciable vapor pressure. They make up a major class of air pollutants.I his class includes not only pure hydrocarbons but also partially oxidized hydrocarbons (organic acids, aldehydes, ketones), as well as organics containing chlorine, sulfur, nitrogen, or other atoms in the molecule. 

Sulfur analogues of well known organic compounds with NO (nitroso) or NO2 (nitro) functionalities also exhibit different stabilities and/or structures compared to those of RNO or RNO2. For example, there are no stable C-thionitroso compounds RN=S (R = alkyl, aryl), although Ai,/V -dimethylthionitrosoamine Mc2NNS can be isolated (Section 10.2). 

Modem commercial detergents are mixtures. Their most important component is a surfactant, or surface-active agent, which takes the place of the soap. Surfactant molecules are organic compounds with a structure and action similar to those of soap. A difference is that they typically contain sulfur atoms in their polar groups (4). 

Although it does not deal with the direct redox processes of sulfur organic compounds, the use of sacrificial electrodes, both cathodes and anodes producing... 

Moreover, European regulations in 2005 restricted the sulfur content in diesel fuel to SOmgkg. Sulfur organic compounds are known to provide diesel fuel with a lubricity that will disappear as the regulations take effect. Addition of biodiesel at a level of 1-2% to diesel blends has the effect of restoring lubricity through an antiwear action on engine injection systems, which is specific for polar molecules. 

Treatment of organic compounds with sulfur tetrafluoride, hydrogen fluoride and approximately an equimolar amount of chlorine results in chlorofluorination giving high yields of chlorolluoro derivatives. 

A mixture of Sg and phosphorus(V) sulfide may also be used to sulfurize organic compounds certain epidisulfanes are transformed to epitrisulfanes. The reaction of SCI2 with 1,4-diethoxybenzene, catalyzed by A CI, in CS2 or CHCI3, yields a bis-tetrasulfane in which two S4 units bridge the two benzene rings. ... 

The American 1970 Clean Air Act defined ambient air quality standards (NAAQS) in the United States for atmospheric ozone, NO, lead, carbon monoxide, sulfur oxides, and PM-10 (particulate matter less than 10 p.m). The strategy to reduce levels of lead, NOx, PM-10, and to some extent carbon monoxide was to control emissions from automobiles that included the phasing-out of leaded fuel. As previously noted, ozone is a product of the photochemical reaction of volatile organic compounds with NOx (photochemical smog), so the balance between organic compounds and NOx pollutants is important in meeting target ozone levels (e.g., 0.12 ppm). Emissions from stationary sources is an important factor, and limits have been set for them. Because of low pressure drop requirements, coated monolithic catalysts... 

Manganese(ll) sulfate is formed as a byproduct in the oxidation of organic compounds with manganese(IV) oxide in the pre.sence of sulfuric acid, e.g. in the production of p-anisaldehyde. Aniline oxidation to p-benzoquinone is no longer industrially important in Western industrialized countries, so most MnSOg is produced from MnO or MnCOv... 

Kuhn-Roth method for C-methyl determination. Oxidation of organic compounds with chromic and sulfuric acids in such a manner that the C-methyl groups are converted to acetic acid which can be assayed volumetrically. The method has been modified and extended (1) to saturated fatty acids and alcohols containing up to about 20 carbon atoms, and (2) to aliphatic long-chain compounds of very high molecular weight. 

Natural vulcanization, or reaction of organic compounds with sulfur compounds, which renders the sulfur-linked materials less available for degradation (e.g. Kohnen et al. 1992). However, this process is not likely to be significant in many marine environments as it is requires low iron availability and abundant reduced-sulfur species.

In the experiment of hydrogenation with vanadia catalyst it was found that the addition of sulfur organic compounds does not alter the reaction,... 

Sulfur was supplied either as a powder or a vapor (in this case CO2 was preheated to 450° C), the gas pressure was 60-120 Torr, the CO2 flow rate was 0.1-0.5 L/s, the sulfur supply rate was up to 0.2 g/s, and the power was about 1 kW. In the case of initially stoichiometric S-CO2 mixture, the product mixture was also stoichiometric [S02] [CO] = 1 2. Molar fractions of oxygen and sulfur-organic compounds in the reaction products were negligible. A minimal energy cost of the process (6-133) with sulfur supplied as a vapor was... 

Sulfur uptake and exchange data 1 referred in Sec. 2.3 indicated substantial differences of alumina supported Pd and Pt, in comparison with the molybdena based catalysts. The mobile sulfur amounts were lower [0.25 Smob/Pd (or /(Pt)] than those experienced with the Mo and W based catalysts. Near to all sulfur, accommodated on the noble metal was mobile and — different from the Mo- and W-based catalysts — participated in the reaction the sulfur mobility was substantially higher due to the much lower S-Pd and S-Pt bond strengths. This indicates that the HDS mechanism, detailed above for Mo based catalysts cannot be valid for the noble metals. Again, the number of vacancies for bonding sulfur-organic compounds is not limiting, as in the case with monometallic Co and Ni.
