Make up the reaction equation: Butane – butene-1 – butane – ethane – ethyl alcohol – ethene

Make up the reaction equation: Butane – butene-1 – butane – ethane – ethyl alcohol – ethene – bromoethane – ethene – co2

1. Catalytic dehydrogenation of butane, 500 ° C.
2C4H10 => CH2 = CH-CH2-CH3 + CH3-CH = CH-CH3.
2. The reaction of hydrogenation of butene-1.
CH2 = CH-CH2-CH3 + H2 = CH3-CH2-CH2-CH3.
3. Cracking of butane.
C4H10 = C2H6 + CH2 = CH2.
4. Ethane dehydrogenation, temperature, Ni catalyst.
C2H6 => CH2 = CH2 + H2.
Hydration of ethylene to ethyl alcohol.
CH2 = CH2 + H-OH = CH3-CH2-OH.
5. Dehydration in the presence of sulfuric acid.
C2H5OH => CH2 = CH2 + H2O.
6. Hydrohalogenation of ethylene.
CH2 = CH2 + HBr => C2H5Br + H2O.
7. Reaction of bromoethane with an alcoholic alkali solution.
C2H5Br + NaOH => CH2 = CH2 + NaBr + H2O.
8. Combustion of ethylene.
CH2 = CH2 + 3O2 = 2CO2 + 2H2O.
