A type of hydrocarbon, such as benzene or toluene, added to gasoline in order to increase octane Some aromatics are toxic
Chemical classification relating to the structure of hydrocarbons aromatic hydrocarbons have carbon atoms arranged in rings with some of the electrons shared over the whole ring, for example benzene and naphthalene
A type of solvent based on benzene ring molecules Aromatics are often used as diluents Example are benzene, xylene, and toluene
Class of hydrocarbons that have at least one benzene ring as part of their structure Generally describes benzene and benzene derivatives These products are used as components of unleaded gasolines and as feedstocks for petrochemicals such as cyclohexane and paraxylene, both of which are used in end products like nylons and polyesters
Aromatics is the generic term for annular unsaturated hydrocarbons of the benzene type Well-known aromatics are benzene, toluene and xylenes
One of the three principal groups or series of hydrocarbon compounds that occurs naturally in crude oil New formulations of gasoline with increased octane levels often contain increased amounts of aromatics
A type of hydrocarbon that contains a ring structure, such as benzene and toluene They can be found for instance in gasoline
This is a type of chemical compound referred to as a cyclic organic due to it's circular structure They are found in nearly all gasolines, normally as toluene Xylene is less common, and benzene is restricted to very low levels due to toxicity
A class of organic compounds containing a resonant, unsaturated ring of carbon atoms Included are benzene, naphthalene, anthracene, and their derivatives
A large family of hydrocarbon compounds based on the benzene structure Chemists link the name aromatic to the exceptional stability that derives from the benzene structure; see Benzene
Affects digestive system and nutrition due to its ability to stimulate the appetite and gastric secretion based on the action of the volatile oil or other aromatic principle Aromatics are also used to relieve flatulence, open nasal passages, improve palatability of medicines or give a psychological boost to top of page
having a strong distinctive fragrance; "the pine woods were more redolent"- Jean Stafford (chemistry) of or relating to or containing one or more benzene rings; "an aromatic organic compound
Belonging to a class of carbon compounds derived from benzene or containing one or more benzene rings such as benzene, phenol, stryrene, toluene, and xylene
An aromatic plant or food has a strong, pleasant smell of herbs or spices. an evergreen shrub with deep green, aromatic leaves = fragrant. having a strong pleasant smell = fragrant
unsaturated hydrocarbon identified by one or more benzene rings or by chemical behavior similar to benzene The benzene ring is characterized by three double bonds alternating with single bonds between carbon atoms (compare with olefins) Because of these multiple bonds, aromatics are usually more reactive and have higher solvency than paraffins and naphthenes Aromatics readily undergo electrophylic substitution; that is, they react to add other active molecular groups, such as nitrates, sulfonates, etc Aromatics are used extensively as petrochemical building blocks in the manufacture of pharmaceuticals, dyes, plastics, and many other chemicals
1 A compound containing a series of benzene (6 Carbon) rings; so named because many have a distinctive odor 2 An organic compound that contains a benzene ring or that has properties similar to that of benzene; often detectable by NMR after the existence of a ring current
Originally mainly from Europe and America, these have been enthusiastically taken up by the younger smoker, with rich flavours like cherry, orange, chocolate, coffee, whisky and many more additives
A class of hydrocarbons consisting of cyclic conjugate carbon atoms, such as benzene or toluene, commonly added to gasoline in order to increase octane Some aromatics are toxic
A vegetable, herb, or spice that gives food a lively fragrance and flavor In classic cooking, a reference to "aromatics" most often means onions, carrot, and celery
A major group of unsaturated cyclic hydrocarbons containing one or more rings (e g , benzene) (These highly reactive and chemically versatile compounds have a strong, but not unpleasant, odor; thus the name aromatic )
