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.
