    • PURPOSE: A purification method for highly pure dicyclopentadiene is provided to raise a pyrolysis rate of dicyclopentadiene and to suppress the polymerization of dicyclopentadiene using a specific hydrocarbon compound having a boiling point which is similar to that of dicyclopentadiene as a subfluid. CONSTITUTION: A purification method for highly pure dicyclopentadiene comprises the steps of: (a) thermally decomposing a hydrocarbon compound with 150-190 °C as a subfluid to crude dicyclopentadiene; (b) separating cyclopentadiene by distilling the thermally decomposed mixture; and (c) preparing dicyclopentadiene by performing dimerization of the separated cyclopentadiene.
    • 目的:提供高纯度二环戊二烯的纯化方法,以提高二环戊二烯的热解速度,并使用沸点与二环戊二烯相似的特定烃化合物作为亚流体来抑制二环戊二烯的聚合。 构成:用于高纯度二环戊二烯的纯化方法包括以下步骤:(a)将150-190℃的烃化合物作为亚流体热分解成粗二环戊二烯; (b)通过蒸馏热分解的混合物分离环戊二烯; 和(c)通过进行分离的环戊二烯的二聚制备二环戊二烯。
