    • A process by which tetracyclododecene for use as a material for cycloolefin (co)polymers having excellent optical properties, high transparency, heat resistance, and oil-absorbing properties can be continuously and stably produced over long even from inexpensive crude DCPD. In the process for the continuous production of a tetracyclododecene compound, a 2-norbornene compound is separated and recovered after reaction and reused as a starting material. Thus, the material is effectively utilized and the target compound can be efficiently synthesized. Further, at least part of a 2-methyl-2-norbornene compound which generates as a by-product and is apt to come into the 2-norbornene compound to be circulated is removed from the system. Thus, adverse influences of the accumulation of that by-product are diminished to enable the operation to be stably and continuously conducted over long.

    • A process by which high-purity tetracyclododecene for use as a material for cycloolefin (co)polymers having excellent optical properties, high transparency, heat resistance, and oil-absorbing properties can be continuously and stably produced over long even from inexpensive crude DCPD. In the process for the continuous production of a tetracyclododecene compound, it is possible to use crude DCPD, which is low-purity dicyclopentadiene, as a starting material. The feed materials to be introduced into a reactor are regulated so that the amount of any one, any two, or all of isoprene, piperylene, a 1-methyl-2-norbornene compound represented by the general formula (4) relative to the total amount of the cyclopentadiene and dicyclopentadiene is within a given range. The tetracyclododecene compound having a high purity can be stably produced over long.
