Carbon oxide sulfide

Cadmium Bromide. The hydrated bromide is prepared by dissolution of cadmium carbonate, oxide, sulfide, or hydroxide in hydrobromic acid. The white crystalline material is cadmium bromide tetrahydrate [13464-92-1], CdBr2 4H2O, Ai/ 29s —1492.55 kJ/mol (—356.73 kcal/mol) (3)... 

Investigation of transformations of the zwitterion 207 led to the elaboration of a new synthetic route to imidazo[ 1,2-t]-thiadiazines <2003JOC4791>. Treatment of this compound 207 with carbon disulfide in the presence of sodium hydroxide resulted in elimination of carbon oxide sulfide and in formation of the cyclized product 208.

Most metals occur in nature as minerals—the silicates, carbonates, oxides, sulfides, phosphates, and chlorides that make up the rocks of the earth s crust. The type of mineral in which a metal is found depends on the metal s location in the periodic table. Minerals from which metals can be produced economically are called ores. 

Without looking at Figure 21.2, predict whether these elements are likely to be found in nature as carbonates, oxides, sulfides, or in uncombined form. Explain.

This group can be supplemented also by amalgam electrodes (or other liquid electrodes) and electrodes fabricated from nonstoichiometric solids capable of changing their composition reversibly (intercalation compounds based on carbons, oxides, sulfides, and multicomponent salts, particularly, Li-intercalating electrodes of batteries).

Odorants are blends of butyl and propyl mercaptanes sometimes containing dimethylsulfide and methylethylsulfide in the US [107]. In Europe the preferred odorants are dimethylsulfide and tetrahydrothiophene [107]. European natural gas contains up to 20 ppm carbon oxide sulfide, owing to the higher hydrogen sulfide concentration of the gas, which then reacts with carbon dioxide. 

At temperatures below 300 °C, hydrogen sulfide can be reduced to below 100 ppb by zinc oxide in the absence of carbon monoxide and steam [294]. At higher temperatures, a mixture of zinc oxide and titania avoids the partial reduction of zinc oxide by the hydrogen contained in the reformate [293]. While zinc oxide has a high adsorption capacity of around 10 g S per g zinc oxide in dry gas, this value decreases considerably in the presence of steam to 0.1 g S per g zinc oxide [107]. According to Li an King, the addition of 1 vol.% carbon monoxide lowered the sulfur removal capability of their zinc oxide adsorbent [294]. The formation of carbon oxide sulfide by the reaction ... 

However, the formation of carbon oxide sulfide is suppressed by binding the zinc oxide with acidic alumina [295]. Sulfate formation can be suppressed by suitable composition of the oxide adsorbent. 

Lampert presented a catalytic partial oxidation technique for sulfur compounds that was developed by the former Engelhard (now BASF) corporation [296]. The sulfur compounds of natural gas or liquefied petroleum gas were converted into sulfur oxides at a low 0/C ratio of 0.03 in a ceramic monolith over a precious metal catalyst. These sulfur oxides were then adsorbed downstream by a fixed adsorber bed, which contained adsorption material specific to sulfur trioxide and sulfur dioxide, which could trap up to 6.7 g sulfur per 100 g adsorbent. The partial oxidation was performed at a 250 °C monolith inlet temperature, the adiabatic temperature rise in the monolith amounted to 20 K. Light sulfur compounds usually present in natural gas and liquefied petroleum gas, such as carbon oxide sulfide, ethylmercaptane, dimethyl sulfide and methylethyl sulfide, could be removed to well below the 1 ppm level. Exposure of the monolith to an air rich fuel/air mixture at temperatures exceeding 150 °C had to be avoided. The same applied for contact with fuel in the absence of air regardless of the temperature.
