What does volatilised mean?
Volatilised is the past tense and past participle of the British-English verb volatilise, and it most often describes a substance that has been converted into vapour. In laboratory, pharmaceutical, and industrial contexts, it indicates an intentional process: a liquid or other material is released as a gas before it can be analysed, captured, or used. A volatilised solvent, for example, has entered the gaseous state. The word can also mean made volatile, with volatile understood as liable to rapid change; in that broader sense, it may be used of substances and, occasionally, of unstable situations. The spelling is recognisably British, while US English generally uses volatilized. Volatilised is more technical and formal than everyday alternatives such as vaporised or evaporated, and its exact sense depends on context. Its history also links everyday ideas of instability with the literal image of a liquid becoming an airborne vapour.

Etymology of volatilised
The verb belongs to the English family of volatile, which entered Middle English from Old French volatil and ultimately from Latin volatilis, meaning “flying” or “volatile.” That Latin adjective came from volare, “to fly,” reflecting the tendency of a substance to pass into the air as vapour. The later English verb volatilise was formed on the same stem; British English uses -ise, while US English usually writes volatilize.
