1. The method of 1 one kinds of separating ring pentadiene and methyl cyclopentadienes from the mixture that contains dicyclopentadiene and two methyl cyclopentadiene components, this method adopts a high-temperature pyrolysis reactor and two rectifying tower series connection, the mixture that contains cyclopentadiene and methyl cyclopentadiene feeds high-temperature pyrolysis reactor, mixed gas behind the Pintsch process feeds rectifying tower 1, isolates the cut that contains cyclopentadiene and methyl cyclopentadiene at cat head by rectifying;

  • The mixed cut of the cyclopentadiene of rectifying tower 1 cat head extraction and methyl cyclopentadiene feeds rectifying tower 2, cat head extraction cyclopentadiene, extraction methyl cyclopentadiene at the bottom of the tower.
