  2. Triethylamine - Wikipedia

    en.wikipedia.org/wiki/Triethylamine

    Triethylamine is the chemical compound with the formula N(CH 2 CH 3) 3, commonly abbreviated Et 3 N. Like triethanolamine and tetraethylammonium, it is often abbreviated TEA. [8] [9] It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia.

  3. N,N-Diisopropylethylamine - Wikipedia

    en.wikipedia.org/wiki/N,N-Diisopropylethylamine

    DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.

  4. Triethanolamine - Wikipedia

    en.wikipedia.org/wiki/Triethanolamine

    Triethanolamine, or TEOA, is an organic compound with the chemical formula N(CH 2 CH 2 OH) 3. It is a colourless, viscous liquid. It is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. [3] It is a colourless compound although samples may appear yellow because ...

  5. Tetraethylammonium - Wikipedia

    en.wikipedia.org/wiki/Tetraethylammonium

    Tetraethylammonium (TEA) is a quaternary ammonium cation with the chemical formula [Et 4 N] +, consisting of four ethyl groups (−C 2 H 5, denoted Et) attached to a central nitrogen atom. It is a counterion used in the research laboratory to prepare lipophilic salts of inorganic anions.

  6. Non-nucleophilic base - Wikipedia

    en.wikipedia.org/wiki/Non-nucleophilic_base

    As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile.Normal bases are also nucleophiles, but often chemists seek the proton-removing ability of a base without any other functions.

  7. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    The equation is −ΔH = E A E B + C A C B + W. The W term represents a constant energy contribution for acid–base reaction such as the cleavage of a dimeric acid or base. The equation predicts reversal of acids and base strengths. The graphical presentations of the equation show that there is no single order of Lewis base strengths or Lewis ...

  8. Element–reactant–product table - Wikipedia

    en.wikipedia.org/wiki/Element–reactant...

    An element–reaction–product table is used to find coefficients while balancing an equation representing a chemical reaction. Coefficients represent moles of a substance so that the number of atoms produced is equal to the number of atoms being reacted with. [1] This is the common setup: Element: all the elements that are in the reaction ...

  9. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.
