What does volatilisable mean?
Volatilisable is an adjective meaning that something can be converted into a vapour. It is most often used in chemistry, pharmacology, and other technical writing to describe a substance whose volatility matters, especially one that can be volatilised by heating, distillation, or another suitable process. The word does not simply mean that a substance is volatile: “volatile” describes a tendency to evaporate readily, whereas “volatilisable” states that conversion into vapour is possible. In practice, the two descriptions often overlap, and volatilisable is the more explicit choice when discussing a compound that can be vaporised under specified conditions. The term is formal and comparatively uncommon in general prose, but useful because it identifies a property rather than suggesting that vaporisation has already occurred. British English normally spells it with -ise, while the corresponding American form is volatilizable.
adjectiveAble to be converted into a vapour. Used especially of substances that can be volatilised by heating, distillation, or another suitable process.
- Able to be converted into a vapour; capable of being volatilised.
"The compound is volatilisable under these conditions and can therefore be removed by distillation."
"The compound is volatilisable under these conditions and can therefore be removed by distillation."
"The pharmaceutical formulator tested how readily the active ingredient could be volatilisated."
Latin volatilis literally meant “flying,” a fitting ancestor for a word about turning a substance into vapour.

Etymology of volatilisable
The word is a British English formation using the suffix -isable on volatilise. Its vocabulary ancestry runs through English volatilise and volatile to Latin volatilis, an adjective meaning “flying” or “volatile,” derived from volare, “to fly.” Volatilisable thus means “able to be made volatile,” with its usual practical sense being “able to be converted into a vapour.”
How volatilisable is actually used
Chiefly formal and technical, especially in chemistry, pharmacology, and materials science. It is more common in British English than in general American usage.
Easily confused with volatilisable
Both words mean able to be converted into a vapour; “volatilisable” is the British -ise spelling, while “volatilizable” is the American -ize spelling.
“Volatile” describes a substance that readily evaporates, whereas “volatilisable” states that a substance is capable of being converted into vapour.
