Learning
Memory Aids
Mnemonic
Think: 'ADIPose' relates to fat (from Latin *adeps*), but here it refers to a six-carbon chain; 'NITRILE' indicates the -CN functional group. So, a six-carbon chain with nitrile groups at both ends.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'нитрил' (nitrile) alone; the full term is 'адипонитрил'.
- The prefix 'adipo-' is from Latin, not related to the English 'adipose' in everyday meaning.
Common Mistakes
- Mispronouncing as 'adipo-NIGHT-rail'.
- Confusing it with 'acetonitrile'.
- Misspelling as 'adiponitril'.

Frequently Asked Questions
Yes, it is toxic if ingested or inhaled and can cause skin and eye irritation. It requires careful industrial handling.
Adiponitrile is hydrogenated to produce hexamethylenediamine, one of the two monomers (the other being adipic acid) used to make nylon-6,6.
It is a synthetic compound produced on an industrial scale; it is not found naturally in significant quantities.
No, it is a highly technical term with no application in general, everyday English. Its use is confined to specific scientific and industrial contexts.
