摘要：

The reaction of trimethylhydrochinone and isophytol over novel Nafion resin/silica nanocomposite materials with 40 wt% of Nafion in silica produces (all-rac)-alpha-tocopherol in high yield. The in situ prepared nanocomposite materials are more stable than the dispersed Nafion catalysts on pre-formed SiO2-supports with respect to solvent leaching.
