How do you convert acetic acid to acetone?

Answer 1

You can do this very carefully with distillation.

The boiling points of these two are between 25 and 44 Celsius difference, depending on the ratio of acetone and water.

Using distillation, you can boil the mixture gently to around a stable 44 Celsius, which will evaporate the acetone and leave the water. The water will not evaporate unless the temperature reaches 100 Celsius.

Answer 2

Distillation is separation technique that takes advantage of the large difference of the boiling points between two (or more) substances.

Acetone boils at 56.5 °C, while water boils at 100 °C. This difference is quite large (many times you may need to work with a smaller difference, where contamination is quite a possibility) The distillation apparatus is set up; after some boiling, the acetone should evaporate, and then condense into a separate flask while the water remains in the bottom flask.

Answer 3

The easiest way would probably be through simple distillation because the boiling points of acetone and water are more than 25 degrees Celsius apart with water being the higher boiling.

Depending on the ratio of acetone to water you may form an azeotrope - meaning that both the acetone and water will vaporize together and ruin your distillation.

Fractional distillation might help with this.

There is also a technique called azeotropic distillation that is sometimes used to make very dry solvents. The only problem is you would end up with completely dry acetone and water that had small amounts of acetone in it.

Answer 4

1. use LiAlH4 and water to convert acetic acid to ethanol.

2. treat ethanol with thionyl chloride(SOCl2) to get ethyl chloride.

3. now treat this with alcoholic KCN followed by complete hydrolysis to get propanoic acid.

4. now repeat the first step above to get propanol.

5. dehydrate propanol to get propene.

6. now add water to this to get propan-2-ol.

7. use CrO3 in acidic medium (a mild oxidising agent) to get propanone or acetone!!!!

Answer 5

The boiling point of acetone is 56-57oC, that of ethanol 78.37oC. If a mixture of the two compounds are heated together in a retort since the boiling point of acetone is lower its molecules will tend to appear first in the material that condenses back into a liquid. If this is collected it will be mainly acetone. The substance that is collected late in the process of distillation will be mainly ethanol. It's important to understand that, at no point in the distillation will the condensed substance be either pure acetone or pure ethanol. However, multiple fractional distillations can be performed to obtain more and more pure products.

Answer 6

Acetic acid can be converted to acetone through a process called dehydrogenation. This involves removing two hydrogen atoms from acetic acid to create acetone. The most common method for accomplishing this transformation is through the use of a catalyst such as copper or metal oxides at high temperatures.

Answer 7

The goal of distillation of acetone is to purify a sample that is impure. The process will allow you to collect the sample that is pure and discard the impurities.Ê

Answer 8

because they have different boiling points

Answer 9

You could use distillation.
