Viable ketones were butanone, triacetylmethane ( TAM ), 2, 3-pentanedione ( 2, 3-PD ), and acetylacetone; all of which can stabilize radical formation through resonance.
12.
Its main uses are in the production of gasoline ( petrol ) and butadiene, although some 2-butene is also used to produce the solvent butanone via 2-butanol followed by oxidation.
13.
For 2-butanone going to 2-butanol, enthalpy of reaction is-13.75 kcal / mole, which again is in excellent agreement with-14.02 kcal / mole.
14.
Upstream of the former superfund site, the concentrations of acetone, 2-butanone, 4-Methyl-2-pentanone, and Bis ( 2-Ethylhexyl ) Phthalate were all 0 parts per billion.
15.
Although some 2-butanol is used as a solvent, it is mainly converted to butanone ( " MEK " ), which is an important industrial solvent and found in many domestic cleaning agents and paint removers.
16.
Another way to use BGIT is shown in Figure 3 where the thermodynamics of a simplified hydrogenation reaction is compared between an alkene ( 2-methyl-1-butene ) and a ketone ( 2-butanone ).
17.
The concentration of 2-butanone ranged from 46.8 to 88.4 parts per billion and the concentration of 4-Methyl-2-pentanone ranged from 4.5 to 16.1 parts per billion.
18.
Many other methods rely on condensation of carbonyls with diamines for instance the synthesis of 2-thio-6-methyluracil from thiourea and ethyl acetoacetate or the synthesis of 4-methylpyrimidine with 4, 4-dimethoxy-2-butanone and formamide.
19.
Lipoic acid serves as co-factor to the acetoin dehydrogenase complex catalyzing the conversion of acetoin ( 3-hydroxy-2-butanone ) to acetaldehyde and acetyl coenzyme A, in some bacteria, allowing acetoin to be used as the sole carbon source.
20.
3 CH 2 COCH 3 molecule 2-butanone has three sets of chemically distinct hydrogen atoms, and would show three peaks on the diagonal, much as a 1D-NMR spectrum would show three peaks .-- > 1 H COSY spectrum of progesterone
