Make up the reaction equation: methyl ester of acetic acid-methanol-methanal-carbon dioxide

Make up the reaction equation: methyl ester of acetic acid-methanol-methanal-carbon dioxide-carbon monoxide-methane-acetylene-benzene-chlorobenzene

1) To obtain methanol from acetic acid methyl ester, it is necessary to add the most common oxide in nature – water:

CH3-CO-O-CH3 + H2O → CH3OH + CH3COOH;

2) Methanol is oxidized in air and methanal is obtained:

CH3OH + [O] → HCOH + H2O;

3) When methanal interacts with oxygen, we observe the release of carbon dioxide and the formation of water:

HCOH + O2 → CO2 + H2O;

4) Carbon dioxide decomposes into carbon monoxide and water:

2CO2 → 2CO + O2;

5) carbon monoxide reacts with hydrogen in the process of this reaction, we get methane and water:

CO + 4H2 → CH4 + H2O;

6) When exposed to temperature, methane decomposes into acetylene and hydrogen:

2CH4 → C2H2 + 4H2 ↑;

7) We observe the formation of benzene from three acetylene molecules:

3C2H2 → C6H6;

8) Benzene, when interacting with chlorine, gives a new substance – chlorobenzene:

C6H6 + Cl2 → C6H5Cl + HCl.
