Aromatic hydrocarbons oil

Aromatic hydrocarbons are an important series of hydrocarbons found in almost every petroleum mixture from any part of the world. Aromatics are cyclic but  Aromatic hydrocarbons are a special class of unsaturated hydrocarbon based on a six carbon ring moiety called benzene. From: Practical Petroleum 

The aromatic solvents available from Shell chemicals companies include pure aromatics like toluene and xylene (isomer mix) as well as a range of heavier C9 and C10 aromatic solvents sold under the ShellSol* name. The ShellSol grades constitute a versatile range of high boiling, highly aromatic solvents. Mineral oil hydrocarbons (MOHs) are complex chemical mixtures. MOHs are generally derived from crude oil. They mainly consist of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). MOSH comprise open-chain, often branched hydrocarbons (commonly named paraffins) and cyclic, saturated hydrocarbons (commonly Polycyclic Aromatic Hydrocarbons (PAHs) Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They also are produced when coal, oil, gas, wood, garbage, and tobacco are burned. PAHs generated from these sources can bind to or form small particles in the air.

Crude oils from different basins in China, Australia and New Zealand were analyzed to character ize aromatic hydrocarbons produced in different environment. A two-step analytical method is developed for the isolation and characterization of polycyclic aromatic hydrocarbons (PAHs) in crude oil contaminated soil. In the   Among the constituents of crude oil there is a group of substances called polycyclic aromatic hydrocarbons (PAHs). PAHs are aromatic compounds containing from  J Food Prot. 2006 Jan;69(1):199-204. Polycyclic aromatic hydrocarbons in frying oils and snacks. Purcaro G(1), Navas JA, Guardiola F, Conte LS, Moret S.

Polycyclic Aromatic Hydrocarbons (PAHs) Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals that occur naturally in coal, crude oil, and gasoline. They also are produced when coal, oil, gas, wood, garbage, and tobacco are burned. PAHs generated from these sources can bind to or form small particles in the air. 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 anthracene

This is an overview of the special class of hydrocarbons known as arenes or aromatic hydrocarbons. This class includes the molecule benzene and is defined by its alternating double and single bonds between carbon molecules that given a bond character that is sometimes described as 1.5 bonds.
