What is reaction between acetic acid and KOH?

Answer 1

Acetic acid cannot further oxidation to any ketone or whatever, but at some condition it may burn to produce Carbon dioxide and water:

CH3COOH + 2 O2 ----> 2 CO2 + 2 H2O

Answer 2

W. Edward Lendsell and Peter N. Preston of Herriot-Watt University, Edinburgh, have developed (Tetrahedron Lett.2005, 46, 8695. doi("10.1016/j.tetlet.2005.10.038") DOI: 10.1016/j.tetlet.2005.10.038) a new family of Pd catalysts, exemplified by the complex 2. These catalysts efficiently (1 mol %) mediate homologation of benzylic halides such as 1 to the corresponding methyl esters at low temperature (35°C) and modest CO overpressure (3.45 bar).

Sukbok Chang of KAIST, Daejon, Korea has uncovered (J. Am. Chem. Soc. 2005, 127, 16046. doi("10.1021/ja056399e") DOI: 10.1021/ja056399e) a truly remarkable reaction, the hydrative conversion of a terminal alkyne such as 4 to the N-sulfonyl amide 5. The free amide 6 can be released by dissolving metal reduction. It is likely that 5 could be N-alkylated efficiently, including under Mitsunobu conditions. The sulfonyl amide 5may also behave like a Weinreb amide, allowing efficient coupling with organometallic nucleophiles to form the corresponding ketones.

Another remarkable set of transformations has been reported (Org. Lett. 2005, 7, 5237. doi("10.1021/ol052100l") DOI: 10.1021/ol052100l) by Sonia I. Maffioli of Vicuron Pharmaceuticals, Gerenzano, Italy. Exposure of a nitrile 7 to a catalytic amount (as little as 0.5 mol %) of PdCl2 (Pd(OAc)2 served equally well) in the presence of acetamide led to the primary amide 8. Conversely, the same catalyst in the presence of acetonitrile converts the primary amide 8 to the nitrile 7. These reactions run at or slightly above ambient temperature.

Answer 3

There is no reaction. Acetic acid is a kind of carboxylic acid.

Answer 4

The chemical equation is:
CH3COOH + KOH = CH3COOK + H2O
