  2. Kjeldahl method - Wikipedia

    en.wikipedia.org/wiki/Kjeldahl_method

    The Kjeldahl method or Kjeldahl digestion (Danish pronunciation: [ˈkʰelˌtɛˀl]) in analytical chemistry is a method for the quantitative determination of a sample's organic nitrogen plus ammonia/ammonium (NH 3 /NH 4 +). Without modification, other forms of inorganic nitrogen, for instance nitrate, are not included in this measurement.

    Ammonia: inorganic; the precursor to most nitrogen-containing compounds; used to make fertilizer Ammonium hydroxide: aqueous ammonia; used in traditional qualitative inorganic analysis: Azobisisobutyronitrile: organic compound; often used as a foamer in plastics and rubber and as a radical initiator: Baeyer's reagent

    Because the syngas was essentially free of impurities, two axial-flow ammonia converters were used. In early 2000 Uhde developed a process that enabled plant capacities of 3300 mtpd and more. The key innovation was a single-flow synthesis loop at medium pressure in series with a conventional high-pressure synthesis loop.

    Ammonia is used as a reagent to distinguish between the other two. While AgCl dissolves in ammonia (due to the formation of the complex ion [Ag(NH 3) 2] +), Hg 2 Cl 2 gives a black precipitate consisting of a mixture of chloro-mercuric amide and elemental mercury. Furthermore, AgCl is reduced to silver under light, which gives samples a violet ...
