How to get nitrobenzene from calcium carbide?
| January 5, 2021 | education
Let’s compose a chain of transformations for nitrobenzene:
CaC2 – C2H2 – C6H6 – C6H5NO2
Transformation chain solution:
CaC2 + 2H2O = C2H2 + Ca (OH) 2 – acetylene hydration reaction;
3C2H2 = C6H6 – acetylene trimerization reaction;
C6H6 + HNO3 = C6H5NO2 + H2O – benzene nitration reaction.
The substances obtained in the reactions are of practical importance. Acetylene is used in the organic synthesis of oxygen-containing compounds, benzene is an additive to motor fuel for ignition, nitrobenzene is used in the production of industrial explosives.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
