Title:
METHOD FOR PRODUCING DICYCLOPENTADIENE
Document Type and Number:
WIPO Patent Application WO/2022/138860
Kind Code:
A1
Abstract:
A method for producing dicyclopentadiene according to one aspect of the present disclosure comprises: an isomerization dehydrocyclization step wherein cyclopentadiene is produced by subjecting a hydrocarbon mixture, which contains the normal form and iso form of a hydrocarbon having 5 carbon atoms, to an isomerization treatment and a dehydrocyclization treatment; and a dimerization step wherein dicyclopentadiene is produced by dimerizing the cyclopentadiene produced in the isomerization dehydrocyclization step. In the isomerization treatment, at least some of the iso form is isomerized into the normal form.
