Write the reaction equation: C → CH4 → C2H2 → C2H4 → C2H5OH ↓ C2H6

1. C + 2H2 = CH4.
Heating carbon in the presence of a catalyst.
2. 2CH4 = C2H2 + 3H2.
Dehydrogenation of methane.
3.C2H2 + H2 = C2H4.
Hydrogenation of acetylene to ethylene: heating, kat = Ni.
4.CH2 = CH2 + H-OH = C2H5OH.
The Butlerov reaction is the industrial production of ethanol.
Characteristics of the reaction: Hydration is the reaction of the addition of a water molecule with the breaking of a double bond. Flow conditions: t = 250 – 300 ° C, P = 6.1 – 7.1 MPa, catalyst – coal saturated with phosphoric acid.
5. C2H5OH = C2H4 + H2O.
The reaction of ethanol dehydration when heated with conc. sulfuric acid.
C2H4 + H2 = C2H6.
Ethylene hydrogenation to ethane.
