伪-Pinene, 尾-pinene and crude turpentine give similar product distribution in isomerization/dimerization.
Dimerization involves a quick isomerization and the dimers are formed from isomeric compounds.
Crude turpentine can be used to produce chemicals that are generally formed from pure pinenes, suggesting an efficient and cheap way for turpentine utilization.
HPW/MCM-41 is more active than bulk HPW and HPW/Al-MCM-41.
