  2. Propionic acid - Wikipedia

    en.wikipedia.org/wiki/Propionic_acid

    Propionic acid (/ p r oʊ p i ˈ ɒ n ɪ k /, from the Greek words πρῶτος : prōtos, meaning "first", and πίων : píōn, meaning "fat"; also known as propanoic acid) is a naturally occurring carboxylic acid with chemical formula CH 3 CH 2 CO 2 H. It is a liquid with a pungent and unpleasant smell somewhat resembling body odor. The ...

  3. Hell–Volhard–Zelinsky halogenation - Wikipedia

    en.wikipedia.org/wiki/Hell–Volhard–Zelinsky...

    An example of the Hell–Volhard–Zelinsky reaction can be seen in the preparation of alanine from propionic acid.In the first step, a combination of bromine and phosphorus tribromide is used in the Hell–Volhard–Zelinsky reaction to prepare 2-bromopropionic acid, [3] which in the second step is converted to a racemic mixture of the amino acid product by ammonolysis.

  4. Ketonic decarboxylation - Wikipedia

    en.wikipedia.org/wiki/Ketonic_decarboxylation

    Ketonic decarboxylation of propanoic acid over a manganese(II) oxide catalyst in a tube furnace affords 3-pentanone. [5] 5-Nonanone, which is potentially of interest as a diesel fuel, can be produced from valeric acid. [6] Stearone is prepared by heating magnesium stearate. [7]

  6. Ester - Wikipedia

    en.wikipedia.org/wiki/Ester

    Esters of propanoic acid are produced commercially by this method: H 2 C=CH 2 + ROH + CO → CH 3 CH 2 CO 2 R. A preparation of methyl propionate is one illustrative example. H 2 C=CH 2 + CO + CH 3 OH → CH 3 CH 2 CO 2 CH 3. The carbonylation of methanol yields methyl formate, which is the main commercial source of formic acid. The reaction is ...

  7. Propanamide - Wikipedia

    en.wikipedia.org/wiki/Propanamide

    It is the amide of propanoic acid. This organic compound is a mono-substituted amide. [2] Organic compounds of the amide group can react in many different organic processes to form other useful compounds for synthesis.

  8. Methyl propionate - Wikipedia

    en.wikipedia.org/wiki/Methyl_propionate

    Methyl propionate can be prepared by esterification of propionic acid with methanol. Industrially, it is prepared by carboalkoxylation, i.e., the reaction of ethylene with carbon monoxide and methanol in the presence of a catalyst: C 2 H 4 + CO + MeOH → MeO 2 CCH 2 CH 3. The reaction is catalyzed by nickel carbonyl and palladium(0) complexes ...

  9. Ethyl propionate - Wikipedia

    en.wikipedia.org/wiki/Ethyl_propionate

    Ethyl propionate can be synthesized by the Fischer esterification of ethanol and propionic acid: CH 3 CH 2 OH + CH 3 CH 2 CO 2 H → CH 3 CH 2 O 2 CCH 2 CH 3 + H 2 O. It participates in condensation reactions by virtue of the weakly acidic methylene group. [7]
