Definition

Meaning

A chemical name for the compound picric acid, specifically referring to its identity as 2,4,6-trinitrophenol.

An obsolete or highly technical term for a highly explosive and toxic yellow crystalline compound, historically used as an explosive, dye, and antiseptic. Its modern and primary name is picric acid.

Linguistics

Semantic Notes

This term is essentially a historical synonym for 'picric acid' and is rarely, if ever, used in contemporary scientific literature. Its use is confined to historical chemical texts. It combines 'nitro-' (indicating the presence of nitro groups) and 'xanthic' (from Greek 'xanthos' meaning yellow), describing its yellow color.

Examples

By Part of Speech

verb

British English

  • The phenol was nitroxanthicated to form the explosive.

American English

  • The phenol was nitroxanthicated to form the explosive.

adjective

British English

Examples

By CEFR Level

B1
  • This yellow powder is an old explosive called nitroxanthic acid.
B2
  • In the 19th century, nitroxanthic acid was a common name for what we now call picric acid.
C1
  • The synthesis of nitroxanthic acid, or 2,4,6-trinitrophenol, involves the nitration of phenol under controlled conditions.

Learning

Memory Aids

Mnemonic

NITRO (explosive groups) + XANTHIC (think 'xanthophyll' - yellow plant pigment) + ACID = a yellow explosive acid.

Conceptual Metaphor

Not applicable; the term is a literal chemical descriptor.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating 'xanthic' as 'ксантовый' in a general sense; it is a specific chemical/colour root. The standard Russian term is 'пикриновая кислота'. 'Nitroxanthic acid' would be an unnatural, calqued translation.

Common Mistakes

  • Misspelling as 'nitroxantic acid' or 'nitroxanthic'.
  • Using it in modern technical writing instead of 'picric acid'.
  • Confusing it with other nitro compounds like nitroglycerin.

FAQ

Frequently Asked Questions

The compound itself (picric acid) has limited specialized uses, but the name 'nitroxanthic acid' is obsolete and not used in modern science or industry.

It derives from Greek 'xanthos' (yellow), referring to the bright yellow color of the crystalline compound.

You would only encounter it when reading historical chemical literature, old patents, or texts on the history of explosives and dyes.

Yes. Picric acid (nitroxanthic acid) is explosive when dry and toxic, requiring specialist handling.
