in which nitrogen is reacted with hydrogen. The colorless ammonia gas with a pungent smell can be easily liquefied into a nitrogen fertilizer. In fact, about 80 percent of ammonia that is produced is used as fertilizer. It is also used as a refrigerant gas; in the manufacture of plastics,...
Nitrogengascombines with lighted magnesium ribbon forming a white substance that reacts with thewaterforming ammonia gas which has a pungent smell. Nitrogen gasis produced in large volumes in both gas and liquid form by cryogenic distillation, and cryogenic processes can produce very purenitrogen. Ha...
The mechanical work during the dough mixing process breaks some of the hydrogen and disulfide bonds, linking adjacent protein chains, and the new bonds formed are in different positions. Expansion of the gas formed during fermentation produces new bond changes, thus improving the dough extensibility....
The Haber-Bosch process directly synthesizes ammonia from nitrogen and hydrogen and is the most economical nitrogen-fixation process known. About 1909 the German chemist Fritz Haber ascertained that nitrogen from the air could be combined with hydrogen under extremely high pressures and moderately high...
Removal of one electron from •NO creates the nitrosonium cation (NO+) which has the ability to react with nucleophilic centers, producing nitroso compounds. Nitrosyl halides are liberated when •NO reacts with fluorine, chlorine, or bromine. The half-life, solubility, and biological reactivity...
An exothermic gas phase reaction, especially synthesis of ammonia or methanol, is carried out by passing the reactant gas over a catalyst in a first zone in heat exchange with a coolant and then in a second, adiabatic zone and then passing reacted gas directly to a heat recovery zone. ...
Large quantities of nitrogen are used together with hydrogen to produce ammonia, NH3, a colourless gas with a pungent, irritating odour. The chief commercial method of synthesizing ammonia is the Haber-Bosch process. Ammonia is one of the two principal nitrogen compounds of commerce; it has nume...
Achatz revamped his restaurant Alinea with a far-out, multi-course menu and futuristic liquid-nitrogen dishes. FromThe Daily Beast Ammonia is a compound of nitrogen and hydrogen, but it cannot be formed by the direct union of these gases. ...
. The element isused in the Haber process for makingammonia and is also used to providean inert atmosphere in weldingand metallurgy. The gas is diatomicand relatively inert – it reacts withhydrogen at high temperatures andwith oxygen in electric discharges. Italso forms nitrides with certain...
A process for separating nitrogen from a multicomponent gas mixture containing nitrogen and a hydrocarbon, such as natural gas or associated gas, using gas-separation membranes selective for nitrogen
