Chemistry: Post your doubts here! Page 183 XtremePapers

16/3/2013· So the yield of butanone is= (42.4/ 68.1) *100 = 61.96% approx. 62% Butanoic acid - C4H8O2; Mr = 88 If .946 mols of alcohol was used then .946 mols of butanoic should be produced, meaning .946* 88 = 83.2 g of butanoic acid should have been produced theoretically. So yield of butanoic acid = (51.6/83.2) * 100 =61.98% approx. 62%

Methyl Ethyl Ketone - Production, Properties, Appliions and …

Methyl Ethyl Ketone (MEK), also known as butanone, is an organic chemical with the formula CH3C (O)CH2CH3. This dialkyl ketone is a colourless liquid that has a sharp and sweet odour. It occurs in nature in a small amount. However, due to its various appliions, the industrialists produce this chemical on a large scale.

What is Butanone?

Butanone is used as a solvent. A solvent is something that dissolves another compound in order to form a solution. For example, go to your kitchen and take out some sugar and a glass. Fill the

Growth-coupled bioconversion of levulinic acid to butanone

1/9/2019· In general, butanone production scaled directly with acetate consumption. In the case where acetate was supplied in 2 × molar excess, butanone titer increased to 900 mg/L (12.6 mM), reflecting a 74% measurable yield of butanone on LA. In all four cases that we tested, E. coli eMEK4 consumed all provided acetate without significant LA abolism.

  • 19.3. Reductions using NaBH4, LiAlH4 Organic Chemistry II

    Because aluminium is less electronegative than boron, the Al-H bond in LiAlH 4 is more polar, thereby, making LiAlH 4 a stronger reducing agent. Addition of a hydride anion (H: –) to an aldehyde or ketone gives an alkoxide anion, which on protonation yields the corresponding alcohol. Aldehydes produce 1º-alcohols and ketones produce 2º-alcohols.


    Butanone is produced in large quantities. Nearly half of it is used in paints and other coatings because it will quickly evaporate. It dissolves many substances and is used as a solvent in processes involving gums, resins, cellulose acetate and nitrocellulose coatings and in vinyl films. It is also used in the synthetic rubber industry, It is

    Butanoic Acid – Structure, Properties, Production and Uses

    Butanoic acid, on treatment with the water, produces ether and acetic acid. The chemical equation can be given as follows. C₄H₈O₂ + H₂O → CH₃COOH + C₂H₆O Occurrence of Butanoic Acid The triglycerides of butyric acid compose 3 to 4 percent of butter. When the butter goes rancid, the butyric acid liberates from glyceride using the hydrolysis process.

    % yield - The Student Room

    Then, you could work out the nuer of moles of butanone, and setting up an equation, use mole ratios to find out how many moles of the product you had. Then you could use n=m/Mr to find out the theoretical mass (m). Sub the values into % yield = actual mass/theoretical mass x100, and you''d have your answer.
