Methyl Vinyl Ketone Synthesis

Here we use this photochemistry of pyruvic acid to trigger oligomerization of methyl vinyl ketone mvk an α β unsaturated compound generated by the atmospheric oxidation of isoprene.

Methyl vinyl ketone synthesis.

The wieland miescher ketone is the robinson annulation product of 2 methyl cyclohexane 1 3 dione and methyl vinyl ketone. Blaise and maire 1 found that methyl vinyl ketone is a compound with a strong odor characteristic of unsatu rated compounds having a negative group adjacent to one of the carbon atoms having the double bond. In aqueous solution pyruvic acid pa an α keto acid found in both the gas and aqueous phases in the atmosphere photolyzes via a radical mechanism. This compound is used in the syntheses of many steroids possessing important biological properties and can be made enantiopure using proline catalysis.

Industrially it is produced by condensation of acetone and formaldehyde with a subsequent dehydration to give good yields of mvk. Mvk is colorless liquid at room temperature with a distinctive and pungent odor. Methyl vinyl ketone is prepared both on a lab and industrial scale via different routes. Vinyl ketones however are important intermediates in synthesis.

It is a colorless flammable highly toxic liquid with a pungent odor. Methyl vinyl ketone mvk iupac name. Cas 78 94 4 ec number 201 160 6 chemical formula ch coch ch. Methyl vinyl ketone is a widely used organic compound classified as an enone i e an alkene and a ketone.

Typically industrial processes yield 90 97 purity depending on final distillation capability. Butenone is the organic compound with the formula ch 3 c o ch ch 2. It is a reactive compound classified as an enone in fact the simplest example thereof.
