Abstract
The present invention provides an indene composition having a content of indene of 80 to 99.5% by mass, in which a content ratio of a hydrocarbon compound having a condensed ring structure of a 5-membered ring and a 6-membered ring, and having 9 or 10 carbon atoms, in a component contained in addition to indene, is 90% by mass or more, and a content of benzonitrile is 0.5% by mass or less, and a content of sulfur is 5 ppm by mass or less.
Claims3
An indene composition, comprising
- 80 to 99.5% by mass of indene,
- 0.5% by mass or less of benzonitrile,
- 5 ppm by mass or less of sulfur, and
- a non-indene component;
- wherein
- in the non-indene component, a content ratio of a hydrocarbon compound
- having a condensed ring structure of a 5-membered ring and a 6-membered ring, and
- having 9 or 10 carbon atoms is 90% by mass or more,
- the hydrocarbon compound contains an alicyclic compound selected from the group consisting of bicyclo(4,3,0)-2,9-nonadiene, hexahydro-4,7-methanoindene and octahydro-4,7-methanoindene, and
- a content ratio of the alicyclic compound in the indene composition is 0.1 to 0.8% by mass.
