One important family of UV absorber molecules are derived from aromatic compounds known as phenols, which contain a hydrogen-bonded hydroxyl group that plays an important role in the dissipation of the absorbed energy.
Wine is loaded with volatile components that evaporate easily: not just alcohol, but also aromatic compounds like esters and aldehydes.
to produce aromatic compounds and other petrochemicals.
(2018) discussed the alkyd resin enamel-coated particleboards via gas chromatography mass spectroscopy--olfactometry and found that the main odor substances released from the panels were aromatic compounds, aldehydes, and alkanes.
Spicy curries as well as those dishes laden with garlic and onion, cruciferous vegetables like cauliflower/broccoli, red meat and some varieties of cheeses are best avoided during summer as they contain volatile organic aromatic compounds that are released via sweat and give rise to bad body odours.
Low temperature pre-fermentation maceration (cold soaking) to extract color and aromatic compounds is not recommended with high-MP grapes.
The product of this reaction is known as Ruhemann's purple (Rp) [3-4].The literature review shows that study of reactions of ninhydrin is a subject of more interest and some of the useful reactions such as amidoalkylation[5], Knoevenagel condensation [6], oxidation [7,8], reduction [9,10], reaction with enols and aromatic compounds [11], synthesis of heterocyclic compounds [12], Friedel-Crafts type reaction [13-16], Kolbe-Schmitt [17], Passerini [18], Wittig [19] and Morita-Baylis-Hillman [20] have been investigated in this area.
The analytical methods for characterization of the base stock oils used in mineral lubricants (aromatic, naphthenic and paraffinic) include the identification of aromatic compounds by ultraviolet absorption from 260 to 350 nm.
Petrochemicals which also contain some of these aromatic compounds as well as heavy metals consisting of lead, cadmium, chromium, copper, nickel, and vanadium may thus cause adverse health outcomes if exposure to these is not controlled [2].
However, this nonspecific detector may not distinguish inferences, which include a large fraction of aliphatic and aromatic compounds in aerosol samples from alkylated PAH homologues.
Aromatic compounds are one of the major organic compounds that pollute soil, water and air and this is mainly attributed to oil and diesel spills (Becerril et al., 2008; Morlett et al., 2008a).
