<p>[Problem] To provide a trimethylenenorbornane production process capable of producing trimethylenenorbornane, which serves as a raw material of adamantane, with a high efficiency in a raffinate or a heavy raffinate heavy, through high efficiency production of dicyclopentadiene, which serves as a raw material of trimethylenenorbornane, without additionally using a dicyclopentadiene hydrogenation unit or a cyclopentadiene dimerization. column. [solution] A process for the production of dicyclopentadiene is provided which includes introducing a liquid feed containing cyclopentadiene and a C 6 to C 8 fraction into a cyclopentadiene recovery column and carrying out distillation of a fluid containing dicyclopentadiene, obtained by dimerization of at least part of the cyclopentadiene, the cyclopentadiene and the C 6 to C 8 fraction, in which an overhead liquid containing cyclopentadiene and a bottom liquid containing dicyclopentadiene are obtained from the top and the bottom of the recovery column, respectively, and the overhead liquid is refluxed so that a cyclopentadiene content of the overhead liquid is 80 to 99% by mass.</p> |
