  • Description Quinoline is a colourless hygroscopic liquid with characteristic odour. On exposure to light, it turns brown in colour. Quinoline decomposes on heating, and on burning produces toxic fumes including nitrogen oxides. Quinoline reacts with strong oxidants, acids, and anhydrides. Quinoline is only slightly soluble in cold water but dissolves readily in hot water and most organic solvents. Quinoline is combustible. It gives off irritating or toxic fumes (or gases) in a fire. Quinoline is incompatible with strong acids, oxidisers, dinitrogen tetroxide, linseed oil, thionyl chloride, maleic anhydride, and perchromates and reacts violently with most incompatibles. Quinoline is used extensively in the manufacturing of dyes, preparation of hydroxyquinoline sulphate and niacin, as a solvent for resins and terpenes, and as an intermediate in the manufacture of other products. Quinoline is used mainly as an intermediate in the manufacture of other several products, as a catalyst, as a corrosion inhibitor, in metallurgical processes, in the manufacture of dyes, as a preservative for anatomical specimens, in polymers and agricultural chemicals, and as a solvent for resins and terpenes. Quinoline is also used as an anti-malarial medicine. Because of its solubility in water, quinoline has significant potential for mobility in the environment, which may promote water contamination. Potential exposure to quinoline also occurs from the inhalation of cigarette smoke. Quinoline breaks down quickly in the atmosphere and water.
  • Uses Preserving anatomical specimens; manufac- ture of quinolinol sulfate; niacin and copper-8- quinolinolate; flavoring. Quinoline is used in the manufacture of dyesand hydroxyquinoline salts; as a solvent forresins and terpenes; and therapeutically as anantimalarial agent. It occurs in coal tar insmall amounts. Quinoline is used as an intermediate in the production of quinoline-related compounds (e.g., 8-hydroxyquinoline). Its multiple uses include solvent, preservative, flavoring agent in medicine, colorant in dyes and paints, and also a component of some fungicides. It is also a solvent for resins and terpenes and is used in the production of paint. Quinoline used as a coloring additive in foods, such as Quinoline Yellow, has increased the concern that quinoline that is found in these processes may contribute to the development of cancers later in life. Quinoline is also an antimalarial agent. Sources of quinoline include petroleum and coal processing, wood preservation, and the use of shale oil.
