How is methyl vinyl ketone prepared from acetone?
Production. MVK has been prepared industrially by the condensation of acetone and formaldehyde, followed by dehydration. Similarly it is prepared by the Mannich reaction involving diethylammonium chloride and acetone, which produces the Mannich adduct: CH3C(O)CH3 + CH2O + [H2NEt2]Cl → [CH3C(O)CH2CH2N(H)Et2]Cl + H2O.
How to synthesize methyl vinyl ketone?
Methyl vinyl ketone is prepared both on a lab and industrial scale via different routes. Industrially, it is produced by condensation of acetone and formaldehyde with a subsequent dehydration to give good yields of MVK. Typically industrial processes yield 90-97% purity depending on final distillation capability.
What is methyl vinyl ketone used for?
Methyl vinyl ketone (MVK) is a colorless to light yellow liquid at ambient temperature and pressure. It is used in the production of polymer systems to produce plastics and resins and as an intermediate in the production of vitamin A and steroids (HSDB 2003).
What is the boiling point of methyl vinyl ketone?
81.4 °C

What is the structure of vinyl hydroquinone?
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C6H4(OH)2. It has two hydroxyl groups bonded to a benzene ring in a para position.
What is Ketone formula?
The general formula of ketones is, CnH2nO. The simplest ketone is of 3 carbon atoms, so its formula will be, C3H6O, called as propanone, it can also be written as, CH3O||CCH3, the carbon of the ketone is counted with the carbon of the hydrocarbon. Hence, the general formula for ketones is CnH2nO.
What’s the formula for hydroquinone?
C6H6O2
