摘要：

Various types of alcohols and phenols are converted to the corresponding tetrahydropyranyl (THP) ether using a catalytic amount of solid silica-based sulfonic acid. The catalyst shows high thermal stability (up to 300 degrees C) and can be recovered and reused for at least eight reaction cycles without loss of reactivity. (c) 2005 Published by Elsevier B.V.
