diazotize

Thân thiện

The chemist diazotizes the aromatic amine in a laboratory flask.

Definition

Verb (Chemistry): To convert an aromatic primary amine into a diazonium salt (a diazo compound) through a chemical reaction with nitrous acid, typically at low temperatures. This is a key step in the synthesis of azo dyes and other important organic compounds.

Usage

The verb "diazotize" is used in technical, chemical contexts. It is a transitive verb, requiring a direct object (the amine being converted). * The chemist needed to diazotize the aniline before coupling it with the phenol. * This amine is difficult to diazotize under standard conditions. * The procedure instructs you to diazotize the compound in an ice bath.

Advanced Usage

• Passive Voice: Often used in procedural descriptions.
  • Once the amine is diazotized, it must be used immediately as the diazonium salt is unstable.
• Gerund/Noun Form: "Diazotization" is the noun form for the process.
  • The diazotization reaction must be carried out below 5°C.

Variants and Related Words

• Diazotization (n): The chemical process of diazotizing.
• Diazonium salt (n): The product of the diazotization reaction.
• Diazo compound (n): A broader class of compounds containing the R-N₂⁺ group.

Synonyms

• Convert to a diazonium salt (descriptive synonym, not a single word).

Antonyms

• Reduce (in a general chemical sense, as diazotization is a specific type of oxidation/nitrosation).
