Abstract

The invention discloses a method for directly synthesizing hanging type tetrahydrodicyclopentadiene from cyclopentadiene by a one-pot method, which comprises the following steps: by taking cyclopentadiene as a raw material, carrying out Diels-Alder reaction and hydrogenation-isomerization reaction under the action of a molecular sieve supported metal bifunctional catalyst, and obtaining hanging type tetrahydrodicyclopentadiene by the one-pot method, the molecular sieve supported metal bifunctional catalyst comprises a carrier and active metal supported on the carrier. The molecular sieve supported metal catalyst is used for converting cyclopentadiene into hanging type tetrahydrodicyclopentadiene for the first time, the hanging type tetrahydrodicyclopentadiene with high added value is directly synthesized through Diels-Alder, hydrogenation, isomerization and a one-pot method, the conversion rate can reach 100%, and the method can be used for actual industrial production.
