Convert ethyl alcohol to vinyl acetate

In summary, the conversation is discussing the steps needed to convert ethyl alcohol to vinyl acetate. The suggested solution involves using conc. H2SO4 at 120 degrees to form ethene, then adding Br2 in CCl4 to obtain 1 2 dibromoethane. Next, NaNH2 is added to form ethyne, which can then be converted to vinyl alcohol using H2SO4, H2O, and Hg2+ salt. However, it is noted that this method may not yield desired results and alternative methods may need to be explored.

Homework Statement


Convert ethyl alcohol to vinyl acetate ( in not more than 6 steps)..


Homework Equations





The Attempt at a Solution


this is wat i tried:
first added conc. H2SO4 at 120 degrees , ethene is formed , then added Br2 in CCl4 , 1 2 dibromoethane is obtained ...then added NaNH2 and ethyne is formed...

what to do next??any idea??:confused:

Ethyne can be converted to vinyl alcohol if treated with H2SO4, H2O and Hg2+ salt (This is a general reaction that allows to obtain aldehydes/ketones from alkynes (agrees with Markovnikov's rule)). But in reality acetaldehyde would be obtained instead from ethyne and almost none of it will isomerase to vinyl alcohol. So I strongly douubt if you can obtain a vinyl ester from the acetadehyde. It is probably better to first obtain something like the required ester and then get the double bond somehow.

1. What is the chemical equation for converting ethyl alcohol to vinyl acetate?

The chemical equation for converting ethyl alcohol to vinyl acetate is: C2H5OH + CH3COOH + O2 → CH3COOCH2CH3 + H2O.

2. What is the purpose of converting ethyl alcohol to vinyl acetate?

The purpose of converting ethyl alcohol to vinyl acetate is to create a versatile chemical compound that is widely used in the production of adhesives, coatings, and polymers.

3. What are the key steps involved in converting ethyl alcohol to vinyl acetate?

The key steps involved in converting ethyl alcohol to vinyl acetate include: 1) oxidation of ethyl alcohol with oxygen in the presence of a catalyst, 2) esterification of acetic acid with the resulting ethyl acetate, and 3) dehydrogenation of ethyl acetate to form vinyl acetate.

4. What are the main challenges in converting ethyl alcohol to vinyl acetate?

The main challenges in converting ethyl alcohol to vinyl acetate include: 1) finding a suitable and efficient catalyst for the oxidation reaction, 2) avoiding unwanted byproducts and impurities during the esterification and dehydrogenation processes, and 3) ensuring the safety and sustainability of the overall process.

5. Are there any alternative methods for converting ethyl alcohol to vinyl acetate?

Yes, there are alternative methods for converting ethyl alcohol to vinyl acetate, such as using ethylene as a starting material instead of ethyl alcohol. However, the traditional method using ethyl alcohol is still the most commonly used due to its availability and cost-effectiveness.
