초록
이 연구는 C5 유분으로부터 고순도 씨클로펜타디엔(cyclopentadiene)제조 및 Diels-Alder반응을 통한 노보넨 합성시 중합방지에 관하여 연구하였다. 고순도 씨클로펜타디엔 제조시 낮은 반응 온도에서 보다 높은 온도에서 부반응인 중합반응을 억제 할 수 있었다. 중합방지제 TISP의 사용은 보다 높은 CPD의 전환율을 얻을 수 있었고, 100 ppm이상의 중합방지제의 농도가 안정적인 CPD의 생산에 적합하였다. 또한 노보넨 합성시 중합방지제를 첨가 하였을 때 부반응 생성이 억제되었으나, exo와 endo의 선택도는 중합방지제의 종류에는 별로 영향이 없었다.
This research was about anti-polymerization both in the purification process of high purity cyclopentadiene from C5 fraction and in synthesizing norbornene via Diels-Alder reaction. During the purification process of HPCPD, high reaction temperature reduced polymerization reaction as a side reaction better than low temperature. The TISP among the inhibitors got the higher rate of CPD conversion, and over 100 ppm of the concentration of inhibitor was suitable for stable CPD production. In addition, the synthesis of norbornene using inhibitors reduced the side reaction, but the selectivity of endo and exo norbornene form was not affected by the use of inhibitors.
