  2. Dehydration reaction - Wikipedia

    en.wikipedia.org/wiki/Dehydration_reaction

    Alkenes can be made from alcohols by dehydration. This conversion, among others, is used in converting biomass to liquid fuels. [2] The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites.

  3. Solvated electron - Wikipedia

    en.wikipedia.org/wiki/Solvated_electron

    A solvated electron is a free electron in a solution, in which it behaves like an anion. [1] An electron's being solvated in a solution means it is bound by the solution. [2] The notation for a solvated electron in formulas of chemical reactions is "e −".

  4. Mass–energy equivalence - Wikipedia

    en.wikipedia.org/wiki/Mass–energy_equivalence

    A water molecule weighs a little less than two free hydrogen atoms and an oxygen atom. The minuscule mass difference is the energy needed to split the molecule into three individual atoms (divided by c 2 ), which was given off as heat when the molecule formed (this heat had mass).

  5. 1,2-Wittig rearrangement - Wikipedia

    en.wikipedia.org/wiki/1,2-Wittig_rearrangement

    A 1,2-Wittig rearrangement is a categorization of chemical reactions in organic chemistry, and consists of a 1,2-rearrangement of an ether with an alkyllithium compound. [1] The reaction is named for Nobel Prize winning chemist Georg Wittig. [2] [3] The intermediate is an alkoxy lithium salt, and the final product an alcohol.

  6. Ether - Wikipedia

    en.wikipedia.org/wiki/Ether

    A water miscible solvent often found in lithium batteries (b.p. 85 °C): Dioxane: A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed.

  8. Zeisel determination - Wikipedia

    en.wikipedia.org/wiki/Zeisel_determination

    The ensuing reaction results in the cleavage of the ether or the ester into an alkyl iodide and respectively an alcohol or a carboxylic acid. Zeisel determination By heating this mixture, the gases are allowed to come into contact with a piece of paper higher up the test tube saturated with silver nitrate .

  9. Leaching (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(chemistry)

    Biological substances can experience leaching themselves, [2] as well as be used for leaching as part of the solvent substance to recover heavy metals. [6] Many plants experience leaching of phenolics, carbohydrates, and amino acids, and can experience as much as 30% mass loss from leaching, [5] just from sources of water such as rain, dew, mist, and fog.
