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 ]
In chemistry, volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure , a substance with high volatility is more likely to exist as a vapour , while a substance with low volatility is more likely to be a liquid or solid .
Volatolomics is a branch of chemistry that studies volatile organic compounds (VOCs) emitted by a biological system, under specific experimental conditions. Etymology [ edit ]
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C 6 H 5 OH. [5] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C 6 H 5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful handling because it can cause ...
The first reaction with many volatile organic compounds (VOCs) is the removal of a hydrogen atom, forming water and an alkyl radical (R •): • HO + RH → H 2 O + R • The alkyl radical will typically react rapidly with oxygen forming a peroxy radical: R • + O 2 → RO 2
Mellitic acid, which contains no C-H bonds, is considered a possible organic compound in Martian soil. [15] Terrestrially, it, and its anhydride, mellitic anhydride, are associated with the mineral mellite (Al 2 C 6 (COO) 6 ·16H 2 O). A slightly broader definition of the organic compound includes all compounds bearing C-H or C-C bonds.
Perfluoroaromatic compounds are relatively volatile for their molecular weight, with melting and boiling points similar to the corresponding aromatic compound, as the table below shows. They have high density and are non-flammable. For the most part, they are colorless liquids. Unlike the perfluoralkanes, they tend to be miscible with common ...
The volatilome (sometimes termed volatolome [1] or volatome [2] [3] [4]) contains all of the volatile metabolites as well as other volatile organic and inorganic compounds that originate from an organism, [5] [6] [7] super-organism, or ecosystem. The atmosphere of a living planet could be regarded as its volatilome.
