Write the reaction equation: ethane-ethylene-ethanol-bromoethane-butane-butanol-methyl alcohol

1. Reaction of ethane dehydrogenation upon heating:

CH3-CH3 = CH2 = CH2 + H2.

2. The Butlerov reaction – hydration of ethylene under the action of a catalyst:

CH2 = CH2 + H2O = CH3-CH2OH.

3. Reaction of ethanol with hydrogen bromide in the presence of sulfuric acid:

CH3-CH2OH + HBr = CH3-CH2Br + H2O.

4. Wurtz reaction – the formation of butane from bromoethane:

2CH3-CH2Br + 2Na = CH3-CH2-CH2-CH3 + 2NaBr.

5. Getting butanol from butane will proceed in two stages:

a) chlorination in UV light.

CH3-CH2-CH2-CH3 + Cl2 = CH3-CH2-CH2-CH2Cl + HCl.

b) alkaline hydrolysis.

CH3-CH2-CH2-CH2Cl + NaOH = CH3-CH2-CH2-CH2OH + NaCl.

6. Heating butanol with sulfuric acid at 140 ° C.

CH3-CH2-CH2-CH2OH = CH3-CH2-CH2-CH2-O-CH2-CH2-CH2-CH3 + H2O.
