In hydrated SO3clusters, a maximum number of three hydrogen bonds occurs between water and SO3molecules. The binding energies were all negative and increase monotonically, while the cluster adsorption energy increases with the sulfur trioxide cluster size, and reaches a saturation. The thermodynamic ...
Reactions of sulphur trioxide (SO3) with minerals and ores (or potential metallurgical importance) are outlined and their potential applications are briefl... F Habashi - 《Sulphur Institute Journal》 被引量: 0发表: 1975年 CATALYST COMPOSITION FOR CONVERSION OF SULFUR TRIOXIDE AND HYDROGEN PRODUCTI...
Controllable hydrogenation of metal oxides provides a route to tune their electronic and redox properties for desired applications. Here, authors study proton movement into molybdenum trioxide and propose a solution treatment method for controllable metal oxide hydrogenation using metallic cations. ...
Alkaline earth metals tend to react with carbon dioxide and sulfur trioxide and then generate carbonates and sulphates respectively. These substances, however, are soluble in water only in the case of a beryllium group that shows up to be much more soluble than others. The chemical properties of...
Chlorine, chemical element of the halogen group that is a toxic, corrosive, greenish yellow gas, irritating to the eyes and respiratory system. Much chlorine is used to sterilize water and wastes, and the substance is employed either directly or indirect
Chromium forms several commercially valuable oxygen compounds, the most important of which is chromium oxide, commonly calledchromium trioxide or chromic acid, CrO3, in which chromium is in the +6 oxidation state. An orange-redcrystalline solid, chromic acid liquefies gradually when exposed to moist...
The complete hydrogenation of the PI block was achieved using the reducing agent p-toluenesulfonyl hydrazide in p-xylene at 135 °C, as it has already been described in the literature [22]. The exclusive partial sulfonation of the PI segment was realized taking advantage of a sulfur trioxide/...
