Conversion of CH4 to C2H2

The conversion of methane (CH4) to acetylene (C2H2) involves a series of reactions. Here is the step-by-step process:

1. Step 1: Dehydrogenation of Methane - Equation: CH4 → C2H6 - Type of Reaction: Dehydrogenation - Reaction Description: In this step, methane (CH4) loses hydrogen to form ethane (C2H6).

2. Step 2: Dehydrogenation of Ethane - Equation: C2H6 → C2H4 - Type of Reaction: Dehydrogenation - Reaction Description: Ethane (C2H6) loses hydrogen to form ethylene (C2H4).

3. Step 3: Dehydrogenation of Ethylene - Equation: C2H4 → C2H2 - Type of Reaction: Dehydrogenation - Reaction Description: Ethylene (C2H4) loses hydrogen to form acetylene (C2H2).

Conversion of C2H2 to CH3CHO

The conversion of acetylene (C2H2) to acetaldehyde (CH3CHO) involves a reaction called hydroformylation.

1. Hydroformylation of Acetylene - Equation: C2H2 + H2O + CO → CH3CHO - Type of Reaction: Hydroformylation - Reaction Description: Acetylene (C2H2) reacts with water (H2O) and carbon monoxide (CO) to form acetaldehyde (CH3CHO).

Conversion of CH3CHO to CH3COOH

The conversion of acetaldehyde (CH3CHO) to acetic acid (CH3COOH) involves an oxidation reaction.

1. Oxidation of Acetaldehyde - Equation: CH3CHO + [O] → CH3COOH - Type of Reaction: Oxidation - Reaction Description: Acetaldehyde (CH3CHO) reacts with an oxidizing agent ([O]) to form acetic acid (CH3COOH).

Conversion of CH3COOH to CH3COOC2H3

The conversion of acetic acid (CH3COOH) to ethyl acetate (CH3COOC2H3) involves an esterification reaction.

1. Esterification of Acetic Acid - Equation: CH3COOH + C2H5OH → CH3COOC2H3 + H2O - Type of Reaction: Esterification - Reaction Description: Acetic acid (CH3COOH) reacts with ethanol (C2H5OH) to form ethyl acetate (CH3COOC2H3) and water (H2O).

Conversion of CH3COOC2H3 to C2H5OH

The conversion of ethyl acetate (CH3COOC2H3) to ethanol (C2H5OH) involves a hydrolysis reaction.

1. Hydrolysis of Ethyl Acetate - Equation: CH3COOC2H3 + H2O → CH3COOH + C2H5OH - Type of Reaction: Hydrolysis - Reaction Description: Ethyl acetate (CH3COOC2H3) reacts with water (H2O) to form acetic acid (CH3COOH) and ethanol (C2H5OH).

Summary of Reactions:

1. CH4 → C2H2: Dehydrogenation 2. C2H2 → CH3CHO: Hydroformylation 3. CH3CHO → CH3COOH: Oxidation 4. CH3COOH → CH3COOC2H3: Esterification 5. CH3COOC2H3 → C2H5OH: Hydrolysis
