Abstract:
1. A method for synthesizing exo-tetrahydrodicyclopentadiene (exo-THDCPD) using a pseudo-fixed bed ionic liquid reactor, comprising isomerizing an endo-tetrahydrodicyclopentadiene (endo-THDCPD) as a reaction feed with an acidic ionic liquid of aluminum trichloride in a pseudo-fixed bed ionic liquid reactor, wherein reactants float as a droplet from bottom to top of the pseudo-fixed bed reactor, and finally are discharged from a side tube, and wherein a mole fraction of aluminum trichloride in the acidic ionic liquid of aluminum trichloride is from 0.5 to 0.9, a feeding rate of the reaction feed is 0.1-10 g/min, and a temperature for the isomerization is between 25-120° C.
