IUPAC Name: Quinoline
Source: Used as an additive in food for flavoring. Also used in organic synthesis and in the production of herbicides.
Summary: Quinoline is an alkaloid used as an flavor additive in beverages. It is also used in organic synthesis and in the production of herbicides. It is a liquid at room temperature that has a density of 1.0900 g/mL at 25 C. It is soluble in water up to 6,110 mg/L at 25 C. Upon decomposition it will produce gaseous nitrogen oxide. It has an acid dissociation constant of pKa = 4.9. Quinoline is classified by the EPA as a Hazardous Air Pollutant (HAPs). Koc values ranging from 2.84 – 10.9 indicate very high mobility within soil that may cause leaching to groundwater. Upon dissociation the cation products will adsorb to organic carbon. Volatilization from soil and water is expected to be the major method of natural removal.
