CLAISEN REARRANGEMENT OF ALLYL-2,6-DIMETHYLPHENYL ETHER OVER A SOLID SUPERACID UDCaT-5 CATALYST
摘要
4-Allyl-2,6-xylenol finds several applications in a variety of industries. It is prepared by Claisen rearrangement of allyl-2,6-dimethylphenyl ether to 4-allyl-2,6-xylenol using various heterogeneous acid catalysts. Catalysts such as heteropolyacid supported on mesoporous silica, cesium modified heteropolyacid supported on clay, and zirconia based mesoporous UDCaT-5 were used for the studies. UDCaT-5 was found to be superior, reusable, and 100% selective toward the desired product. A kinetic model including mechanistic interpretation is provided.
