Vapour-liquid equilibrium of 2-propanol/water showing positive azeotropic behaviour. An azeotrope (/ ə ˈ z iː ə ˌ t r oʊ p /) [1] or a constant heating point mixture is a mixture of two or more liquids whose proportions cannot be changed by simple distillation. [2]
Volatile anaesthetics, a class of anaesthetics which evaporate or vaporize easily; Volatile substance abuse, the abuse of household inhalants containing volatile compounds; Volatile oil, also known as essential oil, an oil derived from plants with aromatic compounds used in cosmetic and flavoring industries
On planet Earth, the term 'volatiles' often refers to the volatile components of magma. In astrogeology volatiles are investigated in the crust or atmosphere of a planet or moon. Volatiles include nitrogen , carbon dioxide , ammonia , hydrogen , methane , sulfur dioxide , water and others.
Volatility can also describe the tendency of a vapor to condense into a liquid or solid; less volatile substances will more readily condense from a vapor than highly volatile ones. [1] Differences in volatility can be observed by comparing how fast substances within a group evaporate (or sublimate in the case of solids) when exposed to the ...
It is a colorless, fragrant, mildly volatile liquid. [clarification needed] [3] Anethole is only slightly soluble in water but exhibits high solubility in ethanol. This trait causes certain anise-flavored liqueurs to become opaque when diluted with water; this is called the ouzo effect.
Volatile elements may refer to: Volatility (chemistry), a property of elements in physical chemistry; Volatiles, a classification of elements in cosmochemistry and ...
All volatile metabolites detectable by the human nose are termed an 'odour profile'. The association of altered odour profiles with disease states has long been documented in both eastern and western medicine, and recent advances in robotic sample introduction have increased interest in the volatilome as a source for biomarkers that can be used for non-invasive screening for disease.
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] They are common and exist in a variety of settings and products, not limited to house mold , upholstered furniture , arts and crafts supplies, dry cleaned clothing, and cleaning supplies . [ 2 ]
