It is soluble in water and polar organic solvents.
Industrially it is produced by condensation of acetone and formaldehyde with a subsequent dehydration to give good yields of mvk.
Consideration of genotoxicity data on representatives for 13 a ß unsaturated aliphatic ketones with terminal double bonds and precursors from chemical subgroup 1 2 2 of fge 19.
For this reason and because of its low boiling point 56 c 132 8 f which makes it easy to remove by evaporation when no longer wanted it is one.
Table pageindex 1 shows that the polar single bonds in ethers have little such effect whereas hydrogen bonding between alcohol molecules is even stronger.
Scientific opinion of flavouring group evaluation 205 revision 1 fge 205rev1.
The other aldehydes and the ketones are liquids with boiling points rising as the molecules get bigger.
In aldehydes and ketones this charge separation leads to dipole dipole interactions that are great enough to significantly affect the boiling points.
Methyl vinyl ketone is prepared both on a lab and industrial scale via different routes.
