Suitable carbonates include, but are not limited to, carbonates of alkali metals and alkaline earth metals, preferably carbonates of calcium and magnesium. Waste products are metal cations and bicarbonate in solution or dehydrated metal salts, which when disposed of in a large body of water provide...
Due to their strong pozzolanic activity, nano-silica will react with CH released during the hydrating of C3S to produce more C-S-H. Ternary concrete blends shows greater compressive strengths than conventional concrete because the presence of hydration products in large quantities causes cement ...
Alkali halite melt is one of the methods, and is discussed in US Patent No. 4475993 (1984). In this method, the CFA is reacted with aluminium trichloride to form a soluble compound of trace metals in the melt. Gallium was recovered from the melt by elec- trolysis. However, this ...
Thus, we first tested how well the C8TG;OOH isomers could be separated by the addition of water to the mobile phase (methanol). With methanol/water (4:1, v/v), the C8TG;OOH isomer mixture was separated into at least 10 peaks when analyzed in a sensitive selective ion monitoring mode...
provides rheological control and lubricity properties. It is easily dissolved in cold or hot water, resulting in clear solutions. Natrosol™ hec is soluble in glycerol, but insoluble in many organic solvents. It also has good solubility in hydro-alcohol systems with up to 60 percent alcohol. ...
Given, that the most efficient catalysts for NEC-hydrogenation are Ru based and the most efficient ones for 12H-NEC-dehydrogenation are Pd based, potential novel single-catalysts for reversible hydrogen storage should comprise both metals. Synergistic effects of Pd catalysts, when combined with other...
The central contributing factors are reactive oxygen species, such as singlet oxygen, hydrogen peroxide, and hydroxyl radicals; light and photosensitizers; metals; and heat. In a multi-component mixture, tryptophan also commonly reacts with carbonyl-containing compounds, leading to a wide variety of ...
This process requires temperatures high enough to melt the solid alkali metal hydroxide in order for it to react with the cellulose-containing plants and oxidated silicon compounds. It is not necessary to remove the lignin from wood in the process of this invention. When an organic or inorganic...
In addition to the hydrolysis and neutralization reactions above dei scribed, they may be reacted with alcohols, either alone or in the presence of alkali metals or organic or inorganic bases to yield esters which are useful as plasticizers for cellulose derivatives and resins. Examples of such ...
The reactants thus include an alkali metal silicate and a mineral acid, such as sulfuric acid or an acidulating agent such as CO2. When the acidification agent is added to the alkali metal silicate at a certain point during the process, the silica starts precipitating. The addition of the...
