dehydrogenation

dehydrogenation

A chemist observes the dehydrogenation of a hydrocarbon in a laboratory setup.

Definition
  1. Noun:
    • Chemical process: "Dehydrogenation" refers to a chemical reaction in which hydrogen is removed from a compound, often resulting in the formation of a new product, such as an alkene from an alkane.
    • Industrial application: In industrial chemistry, "dehydrogenation" is a key step in producing substances like styrene (from ethylbenzene) or butadiene (from butane).
Usage Examples
  • (Removing hydrogen from ethane produces ethylene.)
  • (Catalysts speed up the hydrogen removal reaction.)
Advanced Usage
  • "Catalytic dehydrogenation": a process using a catalyst to facilitate hydrogen removal.

    • Catalytic dehydrogenation is widely used to produce alkenes from alkanes. (The catalyst helps drive the reaction.)
  • "Oxidative dehydrogenation": a variant where oxygen is used to remove hydrogen, often forming water as a byproduct.

    • Oxidative dehydrogenation can improve yield but requires careful control of temperature. (Oxygen aids hydrogen removal.)
Variants and Related Words
  • Dehydrogenate (verb): to remove hydrogen from a compound.

    • The chemist will dehydrogenate the hydrocarbon in the lab. (The chemist will perform the hydrogen removal process.)
  • Dehydrogenase (noun): an enzyme that catalyzes dehydrogenation in biological systems.

    • Alcohol dehydrogenase is an enzyme that breaks down alcohol in the liver. (It removes hydrogen from alcohol.)
Synonyms
  • Hydrogen removal: the literal description of the process.
  • Dehydrohalogenation: a specific type of dehydrogenation involving removal of hydrogen and a halogen atom (not a perfect synonym, but related).
Related Idioms
  • "To dehydrogenate a molecule": a technical phrase meaning to strip hydrogen atoms from a compound.
    • The reaction conditions were set to dehydrogenate the saturated fat. (To remove hydrogen from the fat molecule.)

Note: No common phrasal verbs or idioms exist for "dehydrogenation" due to its specialized scientific nature.
