An aromatic hydrocarbon, or arene, is a hydrocarbon ring compound.It has alternating double and single bonds between carbon atoms forming rings. Many of the compounds have a sweet scent, hence the term 'aromatic'. The ring of six carbon atoms in aromatic compounds is known as a benzene ring, after the simplest possible hydrocarbon ring, benzene. .
streams of petroleum refineries. They are generally characterised as aliphatic, aromatic and/or cycloaliphatic hydrocarbons with unsaturated double bonds. Hydrogenated or 'water white' resins are produced by reacting the resin with hydrogen. The hydrogenation reaction, the subject of this article, improves colour, odour, UV
Polycyclic aromatic hydrocarbons (PAHs, also polyaromatic hydrocarbons or polynuclear aromatic hydrocarbons) are hydrocarbons—organic compounds containing only carbon and hydrogen—that are composed of multiple aromatic rings (organic rings in which the electrons are delocalized).The simplest such chemicals are naphthalene, having two aromatic rings, and the three-ring compounds .
Apr 01, 2019 · April 1, 2019 Neville Chemical Company is pleased to announce its plans to produce hydrogenated hydrocarbon resins at its Neville Island facility in Pittsburgh, Pennyslvania..

Aromatic hydrocarbons have formulas that can be drawn as cyclic alkenes, making them appear unsaturated, but their structure and properties are generally quite different, so they are not considered to be alkenes. Aromatic compounds serve as the basis for many drugs, antiseptics, explosives, solvents, and plastics (e.g., polyesters and polystyrene).
