C8H6O A colorless liquid, boiling point 169°C.



(also benzofuran), a colorless liquid with a characteristic odor. Melting point, — 28.5°C; boiling point, 170.9°C; density, 1.091 g/cm3 at 20°C; refractive index, nD22.7, 1.5645. It has the following structural formula:

Coumarone is soluble in common organic solvents but is insoluble in water. It is resistant to the action of alkalis and resinifies in the presence of sulfuric acid. Coumarone is contained in coal tar, but it can also be synthesized, for example, by heating o-hydroxy-²-chlorostyrene, HOC6H4CH = CHCl, with an alkali. Products obtained from the copolymerization of coumarone with indene (coumarone-indene resins) are used in industry.
