摘要

Claisen rearrangement of the allyl ethers of phenol, and o-, m- and p-cresols was investigated over the acid forms of the large pore zeolites, BEA, MOR and FAU. The reaction products are allyl phenols and dihydrobenzofurans. Larger catalyst loading, higher temperatures and longer run duration favour the formation of the secondary product, the ring compound. A kinetic analysis of the formation of the different products is presented. The influences of the solvent, zeolite type, Si/Al ratio, substrate reactivity and the effect of reaction parameters are examined by kinetic analysis and discussed.
