Question

Напишите уравнения реакций, с помощью которых можно осуществить цепочку превращений веществ: этилен → этанол → уксусная кислота → ацетат калия → ацетон.

Answer 1

Ответ:

1) CH2=CH2 + H2O → CH3CH2OH (при нагревании в присутствии серной кислоты).

2) 5CH3CH2OH + 4KMnO4 + 6H2SO4 → 5CH3COOH + 4MnSO4 + 2K2SO4 + 11H2O

3) CH3COOH + KOH → CH3COOK + H2O

Возможно в условии было указано ацетат кальция, а не калия. Тогда,

3) 2CH3COOH + CaO → (CH3COO)2Ca + H2O

4) (CH3COO)2Ca → CH3-C(O)-CH3 + CaCO3 (при нагревании)

Chemical Reactions for the Transformation of Ethylene to Acetone

To transform ethylene into acetone, a series of chemical reactions involving several intermediate steps is required. Below are the equations for the reactions involved in the transformation:

1. Ethylene to Ethanol: - The first step involves the hydration of ethylene to form ethanol. - The chemical equation for this reaction is: ``` C2H4 + H2O → C2H5OH ```

2. Ethanol to Acetic Acid: - The next step is the oxidation of ethanol to produce acetic acid. - The chemical equation for this reaction is: ``` CH3CH2OH + 2O2 → CH3COOH + H2O ```

3. Acetic Acid to Potassium Acetate: - Acetic acid can be neutralized with potassium hydroxide to form potassium acetate and water. - The chemical equation for this reaction is: ``` CH3COOH + KOH → CH3COOK + H2O ```

4. Potassium Acetate to Acetone: - The final step involves the thermal decomposition of potassium acetate to yield acetone and potassium carbonate. - The chemical equation for this reaction is: ``` CH3COOK → CH3COCH3 + K2CO3 ```

By following these sequential reactions, it is possible to transform ethylene into acetone.
