Volatile oil

Volatile oil

A substance of oily consistency and feel, derived from a plant and containing the principles to which the odour and taste of the plant are due (essential oil); in contrast to a fatty oil, a volatile oil evaporates when exposed to the air and thus is capable of distillation; it may also be obtained by expression or extraction; many volatile oils, identical to or closely resembling the natural oils, can be made synthetically. Volatile oils are used in medicine as stimulants, stomachics, correctives, carminatives, and for purposes of flavoring (e.g., peppermint oil).

Synonym: ethereal oil.

Ladies and Gents, I am having a bit of a difficulty writing this lab report and I would like some insight! Ok, so I conducted this experiment where I was given methanol. I placed methanol in a flask, put tine foil over the end, poked to holes in it and placed it in a hot bath. I measured the flask b...
