The benzene ring is one of the most common chemical structures in nature. Due to their presence in lignocellulosic biomass, petroleum, and coal, aromatics constitute more than 20% of the earth's biomass - the second-largest abundant carbon source after carbohydrates (Díaz et al., 2013).Pollutant aromatic compounds (PACs) of environmental concern, including …

Optimization of the extraction process for reducing aromatic and/or polyaromatic compounds is of primary interest in crude oil refining. Several solvents are described for carrying out such operations (furfural, N-methyl-pyrrolidone -NMP-, dimethyl-sulfoxide -DMSO-, …) and experimental data and model description are required for the correct design of the separation …
Abstract This study conducts a health risk assessment on compounds of BTEX (benzene, ethylbenzene, toluene, and xylene) and PAHs (Polycyclic Aromatic Hydrocarbons) in a factory's burnt oil processing and recycling unit in the center of Iran. The Chronic Daily Intake (CDI) of BTEX and PAH compounds and the cancer risk and non-cancer risk indices were …
Nomenclature of Aromatic Compounds. The simplest aromatic compounds are benzene rings with one substituent replacing one of the hydrogen atoms. If this substituent is an alkyl group, it is named first, followed in one word with "benzene". The molecule shown below is therefore called ethylbenzene. Figure (PageIndex{5}) ethylbenzene
Aromatic compounds contain a higher percentage of carbon than the corresponding aliphatic compounds. Benzene C 6 H 6 contains 2.3% of carbon while corresponding aliphatic compound hexane C 6 H 14 contains 83.7% of carbon.; Due to the higher percentage of carbon, aromatic compounds burn with sooty or smoky flame while aliphatic …
IMPORTANCE Aromatic compounds have broad applications and are used in many industries, such as the cosmetic, food, fragrance, paint, plastic, pharmaceutical, and polymer industries. The majority of aromatic compounds are synthesized from fossil sources, which are becoming limited. Plant biomass is the most abundant renewable resource on Earth …

Aromatic compounds are an important class of chemicals with different industrial applications. They are usually produced by chemical synthesis from petroleum-derived feedstocks, such as toluene, xylene and benzene. However, we are now facing threats from the excessive use of fossil fuels causing environmental problems such as global warming. …
A modern perfume brand now leverages the unique properties of fragrance oils to create memorable and distinctive scents. The inclusion of aromatic compounds in fragrance oils allows for a complex layering of notes, …
These compounds are meticulously selected for their unique olfactory characteristics, serving as the aromatic palette from which perfumers craft their masterpieces. Unlike natural extracts, aroma chemicals are often synthetically produced to ensure consistency and availability, allowing perfumers precise control over fragrance formulations.
The aromatic compounds p-anisic acid and p-anisaldehyde have been extracted from anise, buckwheat, and fennel (43, 44). However, anethole, which is the main aromatic compound in these extracts, was not converted to protocatechuic acid by the ΔphyA ΔprcA mutant, making these extracts less suitable for protocatechuic acid production.
Aromatic Compounds Examples. Aromatic hydrocarbon, are hydrocarbons containing sigma bonds and delocalized pi electrons between carbon atoms in a ring.For example, benzene. They are known as aromatic due to their pleasant …
Aromatic Compounds. Aromatic compounds are compounds that belong to a large class of unsaturated chemical compounds that are defined by the presence of one or more planar rings of atoms linked together by covalent bonds.. The stability of aromatic compounds is referred to as the aromaticity of the compounds as a result of the delocalization of the shared electrons.
Solution. The benzene ring has two chlorine atoms (dichloro) in the first and second positions. The compound is o-dichlorobenzene or 1,2-dichlorobenzene.; The benzene ring has a methyl (CH 3) group.The …
Anti-Aromatic Compounds. While aromaticity provides some added stability, there also exist similar compounds that have added instability. Chemists call these compounds "anti-aromatic," and like their stable counterpart, they have a planar, cyclic structure with a continuous pi system. However, instead of following Hückel's Law, these ...
