- Butanone is listed as a Table II precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.
- For example, butanone is significantly soluble in water, but these two solvents are not miscible because they are not soluble in all proportions.
- After absorption in water, acidification with concentrated sulfuric acid and extraction with butanone, N-Oleoylsarcosine is obtained in 92.5 % yield.
- ASA can be solvent-welded, using e . g . cyclohexane, 1, 2-dichloroethane, methylene chloride, or 2-butanone.
- Both liquid-phase oxidation of heavy naphtha and the Fischer-Tropsch reaction produce mixed oxygenate streams, from which 2-butanone is extracted by fractionation.
- The experiment succeeded with the trained perfumers used as subjects, who perceived that a mixture of 60 % butanone and 40 % mint carvone smelled like caraway.
- Animal tests have shown that the neurotoxic effect of 2-hexanone may be potentiated by simultaneous administration of 2-butanone ( methyl ethyl ketone, MEK ).
- While drugs sold by Rhone-Poulenc and others used a similar process, the ITC said, they didn't infringe the patent because they substituted the solvent butanone.
- The appeals court had rejected that argument, saying experts in the pharmaceuticals industry would have read the specific claims in Tanabe's patent to cover the use of acetone, but not butanone.
- Viable ketones were butanone, triacetylmethane ( TAM ), 2, 3-pentanedione ( 2, 3-PD ), and acetylacetone; all of which can stabilize radical formation through resonance.
- 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.
- 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.
- 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.
- 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.
- 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 ).
- 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.
- 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.
- 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.
- 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
