Write the reaction equations: methane – nitromethane – methylamine (down arrow nitrogen) methylammonium chloride

Let’s solve the chain of transformations for organic substances:

CH4 – CH3NO2 – CH3NH2 – (CH3NH3) Cl

CH4 + HNO3 = CH3NO2 + H2O – nitration occurs upon heating, with the participation of sulfuric acid, nitromethane is obtained;
CH3NO2 + H2 = CH3NH2 – reduction proceeds in the presence of a palladium catalyst, methylamine is formed;
CH3NH2 + HCl = (CH3NH3) Cl – methyl ammonium chloride was obtained.
The process records show the relationship between hydrocarbons and nitrogen-containing organic compounds. The products of the transformation chain find practical applications, for example, methylamine, are used in the vulcanization of rubber.
