Special definitions
There are a number of special definitions of the terms volatility and volatile commonly used in certain fields of study but which are still within the overall context of chemistry:
Wine making
The wine industry uses the term volatile acids to refer to organic acids that are water-soluble, have short carbon chains (six carbon atoms or less) and which occur in wine. For example: carbonic acid, acetic acid, formic acid, butyric acid and proprionic acid.
Cosmetics and flavorings
Certain volatile oils obtained from plants have distinctive, pleasant aromas which are used in cosmetics and food flavorings. These oils are commonly referred to as essential oils
Coal
Coals contain certain amounts of volatile matter, defined as the portion of a coal sample which, when heated in the absence of air, is released as inorganic and organic gases.
Anesthetics
Inhalational anesthetics, commonly referred to as volatile anesthetics are organic liquids at room temperature which are easily vaporized. Some examples are:halothane, isoflurane and sevoflurane.
