Vapor-phase methyl ethyl ketone will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 13 days. Methyl ethyl ketone has been detected in rain, clouds and fog; therefore, it may be removed from the air by wet deposition.
A alyst like zinc, copper, or bronze needs for the dehydrogenation of Methyl Ethyl Ketone. So, the reaction for production is: CH3CH (OH)CH2CH3 → CH3C (O)CH2CH3 + H2 Wacker oxidation of isobutyl benzene led to the production of methyl acetone. This compound exists at room temperature in a liquid form.
The methyl ketone can produce haloform, the diethyl ketone won’t. The reason for this is the mechanism of the reaction with I₂ (X₂)/OH⁻ that proceeds via the enol. The result of the reaction is the substitution of H adjacent to the carbonyl with the halide.

[Reaction of diethyl oxalate with compounds containing a ketone group and analytical appliions of this reaction. II. Aliphatic and aromatic ketones]
CAS: 78-93-3 Methyl Ethyl Ketone also known as MEK, butanone, 2-butanone, butan-2-one, oxobutane, or methyl acetone is a clear volatile liquid that is soluble in water and has a mild, acetone odour and has the molecular formula C 4 H 8 O, CAS: 78-93-3. It has a flash point of -9°C and a specific gravity of 0.81.
Answer (1 of 2): Think you have this the wrong way round. The methyl ketone can produce haloform, the diethyl ketone won’t. The reason for this is the mechanism of the reaction with I₂ …
During water determination after Karl Fischer (KF) aldehydes and ketones cause side reactions with the normally utilised methanol. Both side reactions, i.e. the formation of acetals and ketals, as well as bisulphite addition, can often be recognised by dragging end points and lead to wrong results. During acetal or ketal formation water is
The addition of acid to the hemiacetal creates an acetal through the following mechanism: 1. The proton produced by the dissociation of hydrochloric acid protonates the alcohol molecule in an acid‐base reaction. 2. An unshared electron pair from the hydroxyl oxygen of the hemiacetal removes a proton from the protonated alcohol. 3.

The total production process of methyl ethyl ketone can be divided into two parts: sec-butanol synthesis and refining; methyl ethyl ketone synthesis and refining. Synthesis and refining of sec-butanol: The n-butene from the C4 separation section is heated and pressurized, and under the action of a alyst, it reacts with water to form sec-butanol.
