Definition of indene in English:



  • [mass noun] A colourless liquid hydrocarbon, obtained from coal tar and used in making synthetic resins.

    • ‘Experiments are extending work on indene chemistry to thermal reactions with three other species: styrene, acenaphthylene and phenanthrene.’
    • ‘The spectra were calibrated with the lines of indene in the 200-1700 cm - 1 region and with the lines of acetone and potassium ferrocyanide in the 1600-2100 cm - 1 region.’
    • ‘The experiment described in A of this example was repeated using 60 parts of indene and 40 parts of chlorobutyl rubber.’
    • ‘The spectra were calibrated to an accuracy of 1 cm - 1 for intense isolated bands with indene as the standard for the high-frequency region.’
    • ‘These indene polymers are suitable as dispergents, for example in dyestuff and pigment compositions.’


Late 19th century: from indole + -ene.
