촉매를 첨가하여, 온도가 100 내지 140 ℃이고, 수소기체 압력이 1 내지 4MPa인 고압솥에서 촉매수소화 반응을 4 내지 6시간 동안 진행하고, 냉각시킨 후 촉매를 여과하며, 감압증류를 거쳐 헥사히드로-3,6-메타노 프탈산 무수물을 얻게 된다. 종래기술에 비해, 본 발명은 저렴한 에틸렌부산물인 혼합 C5를 원료로 하여 히믹무수물을 제조하고, 또한 헥사히드로-3,6-메타노 프탈산 무수물을 추가적으로 합성시킴과 아울러 화공원료인 탈고리화 C5를 얻게 되며, 혼합 C5에 대한 정밀가공 이용을 강화시킴으로써 산업화에 널리 보급되는 응용가치를 갖게 된다.
The invention has been published about the bar, hexahydro-3,6-phthalic anhydride and meta-furnace production method that belongs to the chemical synthesis. The method to obtain a pure water thereof to the maleic anhydride and the mixed C5 as a raw material, through a reaction that absorbs at the temperature 0-5 ℃ directly cyclopenta-diene with maleic anhydride to produce a himik anhydride, was crystallized. Then the resulting anhydride himik Ni-Cu / ZrO
2 or ZnO-Ni-Co / ZnO-ZrO

By adding a catalyst, and filtered off the catalyst after the temperature is conducted for catalytic hydrogenation in an autoclave to 100 and to 140 ℃, the hydrogen gas pressure is 1 to 4MPa for 4 to 6 hours, cooled, hexahydrophthalic via a distillation under reduced pressure 3,6 the gain no meta-phthalic anhydride. Compared to the prior art, the present invention is to prepare a himik anhydride by an inexpensive by-product of ethylene as a raw material mixed C5, and also the hexahydro-3,6-anhydride to meta-no further chemical synthesis as well as the raw material Sikkim de cyclization C5 and it get, by strengthening the use of precision machining for mixed C5 will have a value that is widely used in industrial applications.
