  2. Acetic acid - Wikipedia

    en.wikipedia.org/wiki/Acetic_acid

    acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...

  3. Vinegar - Wikipedia

    en.wikipedia.org/wiki/Vinegar

    Vinegar typically contains from 5% to 18% acetic acid by volume. [1] Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast and ethanol to acetic acid using acetic acid bacteria. [2] Many types of vinegar are made, depending on source materials.

  4. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  5. 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.

  6. Kolbe electrolysis - Wikipedia

    en.wikipedia.org/wiki/Kolbe_electrolysis

    As an example, electrolysis of acetic acid yields ethane and carbon dioxide: CH 3 COOH → CH 3 COO − → CH 3 COO· → CH 3 · + CO 2 2CH 3 · → CH 3 CH 3. Another example is the synthesis of 2,7-dimethyl-2,7-dinitrooctane from 4-methyl-4-nitrovaleric acid: [3] The Kolbe reaction has also been occasionally used in cross-coupling reactions.

  7. Mixed acid fermentation - Wikipedia

    en.wikipedia.org/wiki/Mixed_acid_fermentation

    The methyl red (MR) test can detect whether the mixed acid fermentation pathway occurs in microbes when given glucose. A pH indicator is used that turns the test solution red if the pH drops below 4.4. [12] If the fermentation pathway has taken place, the mixture of acids it has produced will make the solution very acidic and cause a red colour ...

  8. Ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fermentation

    Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it to a foam. Less than 2% ethanol remains after baking. [5] [6] In a contemporary advancement, a group in Germany has been doing the opposite and converting stale bread into ethanol. [7]

  9. Wacker process - Wikipedia

    en.wikipedia.org/wiki/Wacker_process

    Extractive distillation with water removes the lights ends having lower boiling points than acetaldehyde (chloromethane, chloroethane, and carbon dioxide) at the top, while water and higher-boiling byproducts, such as acetic acid, crotonaldehyde or chlorinated acetaldehydes, are withdrawn together with acetaldehyde at the bottom.
