Examples
By Part of Speech
verb
British English
- The technician will etherify the isopropanol to produce the desired compound.
American English
- We need to etherify that alcohol to make the solvent.
adjective

Examples
By CEFR Level
- Isopropyl ether is a chemical used in laboratories.
- It is important to keep isopropyl ether away from flames.
- The scientist used isopropyl ether to separate the organic compounds from the mixture.
- Due to its low boiling point, isopropyl ether evaporates very quickly.
- In the Grignard reaction workup, the product was extracted into three successive portions of anhydrous isopropyl ether.
- The peroxide formation tendency of isopropyl ether necessitates strict inventory control and testing protocols in industrial settings.
Learning
Memory Aids
Mnemonic
Imagine a PROpeller (propyl) made of ICE (iso) flying through the ETHER. 'Isopropyl' = 'ice propeller' in the 'ether' (sky/solvent).
Conceptual Metaphor
A CLEANING AGENT FOR MOLECULES (it dissolves organic compounds, 'washing' them out of mixtures).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'эфир' meaning broadcast/airwaves. It is specifically 'изопропиловый эфир'.
- It is not 'spirit' or 'ethanol' (спирт).
Common Mistakes
- Misspelling as 'isoprophyl' or 'isopropylic'.
- Confusing it with isopropanol (rubbing alcohol), which is a related but different chemical.
- Using 'isopropyl ether' to mean general anaesthetic ether (diethyl ether).

FAQ
Frequently Asked Questions
No, rubbing alcohol is usually isopropanol (isopropyl alcohol). Isopropyl ether is a different compound made from two isopropanol molecules linked by an oxygen atom.
Its primary use is as a solvent in laboratories and industry for extracting or dissolving other organic compounds, and as a reaction medium in some chemical syntheses.
It is highly flammable and its vapours can form explosive mixtures with air. More significantly, it can slowly react with air to form unstable, shock-sensitive peroxides, which pose a major explosion risk.
Extremely unlikely. It is a specialist industrial and laboratory chemical, not a common household product.
