nitration

A chemist carefully performs the nitration of benzene in a laboratory.

Definition

1. Noun:
   • Chemical process: "nitration" is a chemical process by which a nitro group (–NO₂) is introduced into an organic compound, typically by reaction with nitric acid or a mixture of nitric and sulfuric acids.

Usage Examples

• (The chemical process of adding a nitro group to benzene.)
• (The industrial application of the nitration process requires temperature regulation.)

Advanced Usage

• "Electrophilic nitration": a specific type of nitration where the nitro group is introduced via an electrophilic attack, often used in aromatic compounds.

  • Electrophilic nitration of toluene occurs preferentially at the ortho and para positions. (A detailed chemical description of the reaction's site selectivity.)

• "Nitration mixture": a blend of concentrated nitric and sulfuric acids used as a nitrating agent.

  • The nitration mixture must be prepared with caution due to its corrosive nature. (The specific reagent composition used in the process.)

Variants and Related Words

• Nitrate (n/verb): a salt or ester of nitric acid; or the act of treating with nitric acid.

  • Potassium nitrate is commonly used in fertilizers. (A salt containing the nitrate ion.)
  • The laboratory will nitrate the sample for analysis. (To treat with nitric acid.)

• Nitric (adj): relating to or containing nitrogen, especially in a higher oxidation state.

  • Nitric acid is a key reagent in nitration. (The acid used in the process.)

• Nitro (prefix): indicating the presence of a nitro group.

  • Nitrobenzene is a product of benzene nitration. (A compound containing a nitro group.)

Synonyms

• Nitrification: a related but distinct process in soil chemistry where ammonia is converted to nitrates by bacteria. (Note: not a true synonym, but often confused with nitration.)
