PREPARATION METHOD OF 5-VINYL-2-NORBORNENE USING SUPPORTED CATALYSTS CONTAING FLUORIDE COMPOUND

摘要

Provided is a method for preparing 5-vinyl-2-norbornene to improve conversion rate and yield, to enhance the selectivity of 5-vinyl-2-norbornene and dicyclopentadiene and to reduce the selectivity of 3a,4,7,7a-tetrahydroindene of by-product. The method comprises the step of reacting cyclopentadiene and 1,3-butadiene in the presence of a supported catalyst which comprises a support, and 10-50 wt% of a fluoride compound selected from the group consisting of NaF, KF, CsF, MgF2, ZnF2 and NH4F and supported on the support. Preferably the support is selected from the group consisting of alumina, silica, carbon and magnesium oxide. Preferably the reaction is carried out at a temperature of 150-220 deg.C and in a solvent selected from a hydrocarbon-based compound or an aromatic hydrocarbon compound.
