  2. Ammonium cyanate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_cyanate

    The structure of this salt was verified by X-ray crystallography. The respective C–O and C–N distances are 1.174(8) and 1.192(7) Å, consistent with the O=C=N − description. Ammonium cation [NH 4] + forms hydrogen bonds with cyanate anion O=C=N −, but to N, not to O. [1]

  3. Ammonium cyanide - Wikipedia

    en.wikipedia.org/wiki/Ammonium_cyanide

    Ammonium cyanide decomposes to ammonia and hydrogen cyanide, often forming a black polymer of hydrogen cyanide: [1] NH 4 CN → NH 3 + HCN. It undergoes salt metathesis reaction in solution with a number of metal salts to form metal–cyanide complexes.

  4. Wöhler synthesis - Wikipedia

    en.wikipedia.org/wiki/Wöhler_synthesis

    The Wöhler synthesis is the conversion of ammonium cyanate into urea.This chemical reaction was described in 1828 by Friedrich Wöhler. [1] It is often cited as the starting point of modern organic chemistry.

  5. Ammonium carbamate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_carbamate

    Ammonium carbamate can be prepared by reaction of the two gases at high temperature (175–225 °C) and high pressure (150–250 bar). [14] It can also be obtained by bubbling gaseous CO 2 and NH 3 in anhydrous ethanol, 1-propanol, or DMF at ambient pressure and 0 °C. The carbamate precipitates and can be separated by simple filtration, and ...

  6. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes , ketones and carboxylic acid ), as part of many larger functional groups.

  7. Ammonium thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_thiocyanate

    Ammonium thiocyanate is used in the manufacture of herbicides, thiourea, and transparent artificial resins; in matches; as a stabilizing agent in photography; in various rustproofing compositions; as an adjuvant in textile dyeing and printing; as a tracer in oil fields; in the separation of hafnium from zirconium (important for the production of hafnium-free zircalloy for use in nuclear fuel ...
