Let us write down the reaction equations for the transformation chain:
3C2H2 = C6H6 – trimerization reaction, benzene is formed;
C6H6 + HO – NO2 = H2O + C6H5NO2 – nitration, nitrobenzene was obtained;
C6H5NO2 + 3H2 = C6H5NH2 + 3H2O – reduction, phenylamine (aniline) was isolated;
C6H5NH2 + HCl = C6H5NH3Cl – exchange, while aniline as a base reacts with strong hydrochloric acid.
Reaction products find application, for example, acetylene in metal welding, benzene is an additive in motor fuel, aniline is used as a base for dyes. The reactions confirm the bond between alkynes, arenes, amines.
