cyclotrimethylenetrinitramine
Very Low (Specialised/Technical)Technical/Scientific (Exclusively)
Definition
Meaning
The systematic chemical name for a powerful crystalline high explosive, commonly known as RDX.
A technical term in chemistry, materials science, and military engineering for a nitramine compound (C₃H₆N₆O₆) with high brisance, used in military and industrial applications.
Linguistics
Semantic Notes
Used almost exclusively as a technical identifier. The name is descriptive of its molecular structure (a cyclic compound containing trimethylene and trinitramine groups). In common parlance, the acronym RDX is universally preferred, even among experts.
Dialectal Variation
British vs American Usage
Differences
No significant differences; the term is identical and equally rare in both varieties. The alternative name 'cyclonite' is also used in military contexts in both regions.
Connotations
Purely technical and formal. Carries connotations of military/defence research, explosives engineering, and chemical synthesis.
Frequency
Extremely rare in any non-specialist context. Frequency is identical in BrE and AmE, limited to highly technical documents.

Examples
By Part of Speech
adjective
British English
- The cyclotrimethylenetrinitramine sample was handled with extreme care.
American English
- The cyclotrimethylenetrinitramine compound must be stored under specific conditions.
Examples
By CEFR Level
- The laboratory produced a small quantity of cyclotrimethylenetrinitramine for testing.
- Advanced research focuses on desensitising cyclotrimethylenetrinitramine for safer military applications without compromising its brisance.

Memory Aids
Mnemonic
Cycle (cyclo-) of Three (tri-) Methyl groups (trimethylene) with Three Nitro groups (trinitramine): C3 with N6O6.
Conceptual Metaphor
N/A (Overwhelmingly literal, technical term).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate component parts literally (e.g., 'циклотриметилентринитрамин' is the direct equivalent, but 'гексоген' or 'RDX' are more common technical synonyms).
Common Mistakes
- Misspelling: e.g., 'cyclotrimethylenetrinitramin', 'cyclotrimethylen-trinitramine'.
- Mispronouncing by stressing the wrong syllables or omitting segments due to its length.
