First reaction. To obtain acetylene from potassium carbide, it is necessary to add water to the starting material:
CaC2 + 2H2O -> Ca (OH) 2 + C2H2.
Second reaction. To obtain ethanal from acetylene, it is necessary to carry out a hydration reaction of the starting material:
C2H2 + H2O -> CH3COH.
This reaction takes place in the presence of mercury salts.
Third reaction. To obtain alcohol ethanol from ethanal, it is necessary for hydrogen to react with the starting material:
CH3COH + H2 -> CH3CH2OH.
