FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing an aromatic nitrile compound. Method includes a dehydration reaction for dehydrating an aromatic amide compound. Diphenyl ether is used in said dehydration reaction. Dehydration reaction is carried out while boiling diphenyl ether. Diphenyl ether has a boiling point higher than the boiling point of the aromatic nitrile compound and the boiling point of water and lower than the boiling point of the aromatic amide compound. Invention also relates to a method of producing carbonate ester using said method, which enables regeneration of the aromatic amide compound.
EFFECT: disclosed method reduces number of steps, increases rate and shortens reaction time.
