[Chemical Properties]

Colorless (when freshly distilled) oily liquid. Insoluble in water, soluble in alcohol and oils. Turns brownish if poorly stored (exposure to air and daylight).
B.P. approximately 255°C. Sp.Gr. 0.99.
[Uses]

Trace amounts of 2-ISOBUTYLQUINOLINE are frequently used in perfume compositions along with tenacious (highboiling) fixatives such as Vetiver, Patchouli, macrocyclic musks, Oakmoss products, etc. If not properly fixed, the Quinoline odor will appear with undesirable strength in the dryout of the fragrance. Effective concentrations may be less than 0.1 percent in the total perfume oil. The effect is more that of a general "lift" than actually an odor contribution, and the quinoline odor should not be part of the fragrance picture, but should appear with an undetectable note of radiation and strength. Occasionally used in Tobacco flavor compositions.
[Production Methods]

2-ISOBUTYLQUINOLINE can be produced from alpha-iso-Butylamine and Acrolein.
