Examples

By Part of Speech

verb

British English

  • The catalyst helps dehydrogenize the organic substrate efficiently.
  • Older methods would dehydrogenize the compound using intense heat.

American English

  • This enzyme can dehydrogenize fatty acids in the lab setup.
  • The industrial process is designed to dehydrogenize propane to form propylene.

adverb

British English

  • The compound reacted dehydrogenizingly under those conditions. (Highly contrived/rare)

American English

  • The agent acted dehydrogenizingly on the mixture. (Highly contrived/rare)

adjective

British English

  • The dehydrogenizing agent was added dropwise.
  • They studied the dehydrogenizing reaction mechanism.

American English

  • A dehydrogenizing catalyst is crucial for the reaction.
  • The dehydrogenizing process requires careful temperature control.

Examples

By CEFR Level

A2
  • This word is too difficult for A2 level.
B1
  • Scientists can dehydrogenize some materials. (Simplified)
B2

Learning

Memory Aids

Mnemonic

Think: DE-HYDROGEN-IZE. To take DE-part the HYDROGEN from something (IZE the action).

Conceptual Metaphor

A SUBTRACTION or PURIFICATION process (removing an element to leave a 'purer' or different substance).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Не путать с 'дегидратировать' (dehydrate) – удалять воду, а не водород.
  • Более частый эквивалент – 'дегидрогенизировать' или 'дегидрировать'.

Common Mistakes

  • Misspelling as 'dehydogenize' or 'dehydrogenise'.
  • Confusing with 'dehydrate'.
  • Using it in non-chemical contexts.

FAQ

Frequently Asked Questions

No. 'Dehydrogenize' removes hydrogen (H), while 'dehydrate' removes water (H₂O).

'Dehydrogenate' is more frequently used in modern chemistry.

Almost exclusively in chemistry, chemical engineering, and related scientific research.

No, it is a very low-frequency, technical term unknown to most general English speakers.
