  2. Cyanide - Wikipedia

    en.wikipedia.org/wiki/Cyanide

    Cyanide is quantified by potentiometric titration, a method widely used in gold mining. It can also be determined by titration with silver ion. Some analyses begin with an air-purge of an acidified boiling solution, sweeping the vapors into a basic absorber solution. The cyanide salt absorbed in the basic solution is then analyzed. [47]

  4. Copper (I) cyanide - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_cyanide

    Copper cyanide is a coordination polymer.It exists in two polymorphs both of which contain -[Cu-CN]- chains made from linear copper(I) centres linked by cyanide bridges.In the high-temperature polymorph, HT-CuCN, which is isostructural with AgCN, the linear chains pack on a hexagonal lattice and adjacent chains are off set by +/- 1/3 c, Figure 1. [5]

  5. Acetyl cyanide - Wikipedia

    en.wikipedia.org/wiki/Acetyl_cyanide

    Aldol condensation can occur when acetyl cyanide reacts with (Z)-but-2-enal to form (2E,4E)-hexa-2,4-dienoyl cyanide: The photochemical and thermal reactions of acetyl cyanide have been extensively studied. For example, formyl cyanide does not undergo unimolecular decomposition to HCN and CO spontaneously. However, acetyl cyanide, also a member ...

  6. Cyanogen - Wikipedia

    en.wikipedia.org/wiki/Cyanogen

    Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.

  7. Formyl cyanide - Wikipedia

    en.wikipedia.org/wiki/Formyl_cyanide

    Formyl cyanide is a simple organic compound with the formula HCOCN and structure HC(=O)−C≡N. It is simultaneously a nitrile (R−C≡N) and an aldehyde (R−CH=O). Formyl cyanide is the simplest member of the acyl cyanide family. It is known to occur in space in the Sgr B2 molecular cloud. [1]

  8. Acetone cyanohydrin - Wikipedia

    en.wikipedia.org/wiki/Acetone_cyanohydrin

    In the laboratory, this compound may be prepared by treating sodium cyanide with acetone, followed by acidification: [3]. Considering the high toxicity of acetone cyanohydrin, a lab scale production has been developed using a microreactor-scale flow chemistry [4] to avoid needing to manufacture and store large quantities of the reagent.

  9. Potassium cyanide - Wikipedia

    en.wikipedia.org/wiki/Potassium_cyanide

    Potassium cyanide is a compound with the formula KCN. It is a colorless salt, similar in appearance to sugar , that is highly soluble in water. Most KCN is used in gold mining , organic synthesis , and electroplating .
