A colorless, pungent fuel, NH3, thoroughly familiar with produce fertilizers and numerous nitrogen-containing natural and inorganic chemical compounds.
See ammonium hydroxide.
A gaseous element of hydrogen and nitrogen, NH3, with a pungent smell and flavor.
A gaseous compound of hydrogen and nitrogen, NH3, with a pungent scent and flavor: -- also known as volatile alkali, and spirits of hartshorn.
the current name associated with volatile alkali, NH3, previously so called to distinguish it through the much more fixed alkalis.
[capitalized] In zoöl.: An old quasi-generic title of Spirula. Breyn, 1732. A genus of arachnidans.
The great value of ammonia as a fertilizer, mainly by means of ammonium sulphate, renders issue of its offer on a sizable scale among much importance. Until modern times it was acquired primarily from watery ammoniacal liquor which is a by-product regarding the manufacture of coal-gas for illuminating reasons. This supply of offer has been seriously threatened because of the expansion, particularly in the United States, of the usage of carbureted water-gas, in making which little or no ammonia is gotten. Significant improvements, but have been made in methods for the data recovery of ammonia from waste gases of coke-ovens, shale-works, and blast-furnaces, and incredibly huge amounts are now gotten from the previously neglected sources. Probably the most interesting outcomes secured using the high temperature of the modern electric furnace may be the synthetical creation of ammonia through the nitrogen of atmospheric environment and the hydrogen of liquid. Carbon in the shape of coke is combined with lime plus the blend extremely heated in existence of atmospheric nitrogen, offering increase to carbon-monoxid gas and calcium cyanamide (CaCN2). The latter, heated with water under pressure, yields calcium carbonate and ammonia (CaCN2 + 3H2O = CaCO3 + 2N H3). It appears that cyanamide itself may offer, whenever made use of straight as a fertilizer, to provide assimilable nitrogen to growing plants.
