Title: Production of high purity indene and high purity indene
Inventor: TAKIGAWA YASUYUKI
IPC: C07C13/465
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To remove impurities from indene in a simple way and to obtain high purity indene by applying a crystallization method to indene stock oil. SOLUTION: This method is to remove impurities (e.g. indan, benzonitrile, aliphatic hydrocarbons and/or C4-alkylbenzenes) from indene stock oil concentrated through the distillation of a coal-tar fraction and/or a petroleum distillate by a crystallization method preferably at -10 to 0 deg.C. Removal of the impurities are preferably conducted through solid-liquid separation by centrifugation set at -10 to 0 deg.C. For example, the stock oil is cooled down to a lower temperature than -10 deg.C to solidify the stock oil and crushed matter prepared by crushing the solid matter is subjected to solid-liquid separation by a centrifuge set at -10 to 0 deg.C. Filtrate obtained by the solid-liquid separation can be recycled as a raw material for indene stock liquid. Indene with the purity of >=99 wt.% or moreover >=99.5 wt.% can be obtained.
