    摘要: A process for producing 5-vinyl-2-norbornene which comprises the steps of subjecting a liquid raw material in which tetrahydroindene/dicyclopentadiene ratio (by weight) falls within the range of from 5/100 to 80/100 to a thermal decomposition in liquid phase in the presence of an aromatic hydrocarbon solvent having a boiling point of from 250.degree. C. to 300.degree. C. at a reaction temperature of not lower than 200.degree. C. and lower than 240.degree. C. for a reaction time of from 10 minutes to 120 minutes to obtain a liquid reaction mixture (A-1) composed of 50% to 70% by weight of cyclopentadiene, distilling the liquid reaction mixture (A-1) to obtain fraction (B-1) composed of 90% to 100% by weight of cyclopentadiene and fraction (B-2) composed of 60% to 90% by weight of the total of dicyclopentadiene and tetrahydroindene, further distilling the fraction (B-2) to obtain fraction (B-3) composed of 15% to 40% by weight of dicyclopentadiene and fraction (B-4) composed of 60% to 100% by weight of tetrahydroindene, recycling the fraction (B-3) into the liquid raw material, removing the fraction (B-4) out of the system, and subjecting the fraction (B-1) to a Diels Alder reaction with butadiene to obtain a liquid reaction mixture (C-1) composed of 20% to 40% by weight of 5-vinyl-2-norbornene.
