  2. Ethyl iodide - Wikipedia

    en.wikipedia.org/wiki/Ethyl_iodide

    Ethyl iodide is prepared by using red phosphorus, absolute ethanol and iodine. The iodine dissolves in the ethanol, where it reacts with the solid phosphorus to form phosphorus triiodide. [3] During this process, the temperature is controlled. 3 C 2 H 5 OH + PI 3 → 3 C 2 H 5 I + H 3 PO 3. The crude product is purified by distillation.

  3. Iodine clock reaction - Wikipedia

    en.wikipedia.org/wiki/Iodine_clock_reaction

    The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. [1] The iodine clock reaction exists in several variations, which each involve iodine species ( iodide ion, free iodine, or iodate ion) and redox reagents in the presence of ...

  4. Iodine - Wikipedia

    en.wikipedia.org/wiki/Iodine

    It is a colourless gas that reacts with oxygen to give water and iodine. Although it is useful in iodination reactions in the laboratory, it does not have large-scale industrial uses, unlike the other hydrogen halides. Commercially, it is usually made by reacting iodine with hydrogen sulfide or hydrazine: [47] 2 I 2 + N 2 H 4 4 HI + N 2

  7. Sublimation (phase transition) - Wikipedia

    en.wikipedia.org/wiki/Sublimation_(phase_transition)

    Dark green crystals of nickelocene, sublimed and freshly deposited on a cold finger Sublimation of iodine. Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. [1] The verb form of sublimation is sublime, or less preferably, sublimate. [2]

  8. Alcohol oxidation - Wikipedia

    en.wikipedia.org/wiki/Alcohol_oxidation

    Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.

  9. Organoiodine chemistry - Wikipedia

    en.wikipedia.org/wiki/Organoiodine_chemistry

    This application exploits the X-ray absorbing ability of the heavy iodine nucleus. A variety of agents are available commercially, many are derivatives of 1,3,5-triiodobenzene and contain about 50% by weight iodine. For most applications, the agent must be highly soluble in water and, of course, non-toxic and readily excreted.
