Acetylene is obtained from methane by its incomplete decomposition at a temperature of 1500 0 С, methane decomposes to acetylene and hydrogen.
2 CH4 = C2H2 + 3 H2.
Acetylene, adding water, forms ethanal.
С2Н2 + НОН = СН3 –СОН.
Ethanal, reduced with hydrogen, forms ethanol.
СН3 –СОН + Н2 = CH3 – CH2 – OH.
For alcohols, a dehydration reaction is characteristic – the elimination of a water molecule in the presence of concentrated sulfuric acid and upon heating.
CH3 – CH2 – OH (H2SO4) → H2C = CH2 + H2O.
