Hydrocarbons solubility

Webhydrocarbons (PAHs) General description Polycyclic aromatic hydrocarbons (PAHs) are a large group of organic compounds with two or more fused aromatic rings. They have a relatively low solubility in water, but are highly lipophilic. Most of the PAHs with low vapour pressure in the air are adsorbed on particles. When dissolved in Web19 jul. 2011 · In fact, unsaturated and aromatic hydrocarbons are slightly soluble in water- the solubility of toluene in water is ~500mg/L – not very much.
