ABSTRACT:
An exo-tetrahydrodicyclopentadiene is produced from endo-tetrahydrodicyclopentadiene through isomerization reaction. An acidic ionic liquid is used in the isomerization. The isomerization of endo-tetrahydrodicyclopentadiene gives a reaction conversion and a selectivity both higher than 99%. Besides, the ionic liquid used is environmental-friendly and recyclable.
