How will you prepare acetone from Acetyl chloride ?

Explanation

To prepare acetone from acetyl chloride, we can follow a series of chemical reactions. Here is the step-by-step process:

### Step 1: Hydrolysis of Acetyl Chloride
- **Reaction**: Acetyl chloride (CH3COCl) undergoes hydrolysis in the presence of water.
- **Equation**:
\[ \text{CH}_3\text{COCl} + \text{H}_2\text{O} \rightarrow \text{CH}_3\text{COOH} + \text{HCl} \]
- **Product**: This reaction yields acetic acid (CH3COOH) and hydrochloric acid (HCl).

### Step 2: Formation of Calcium Acetate
- **Reaction**: Acetic acid is then treated with calcium hydroxide (Ca(OH)2) to form calcium acetate.
- **Equation**:
\[ 2\text{CH}_3\text{COOH} + \text{Ca(OH)}_2 \rightarrow \text{Ca(CH}_3\text{COO)}_2 + 2\text{H}_2\text{O} \]
- **Product**: This reaction produces calcium acetate (Ca(CH3COO)2) and water.

### Step 3: Distillation of Calcium Acetate
- **Reaction**: The calcium acetate is then subjected to distillation.
- **Process**: During distillation, calcium acetate decomposes to yield acetone.
- **Equation**:
\[ \text{Ca(CH}_3\text{COO)}_2 \xrightarrow{\text{heat}} \text{CH}_3\text{COCH}_3 + \text{CaO} + \text{CO}_2 \]
- **Product**: This process gives acetone (CH3COCH3), along with calcium oxide (CaO) and carbon dioxide (CO2).

### Final Summary
The overall sequence of reactions is:
1. Hydrolysis of acetyl chloride to form acetic acid.
2. Reaction of acetic acid with calcium hydroxide to form calcium acetate.
3. Distillation of calcium acetate to produce acetone.
