Preparation of phenol- or thiophenyl-sulfonic acid functionalized solid acids

摘要

Some aryl sulfonic acid-functionalized solids were prepared by a new method. The catalytic activities of esterification by the prepared aryl sulfonic acid-functionalized solids were also tested.

主权项

1. A method of preparing an aryl sulfonic acid-functionalized solid, comprising:
forming a 3-arylpropyl trimethoxysilane by reacting 3-chloropropyl trimethoxysilane with an aromatic compound; forming an aryl-functionalized solid by grafting the 3-arylpropyl trimethoxysilane onto an inorganic solid material having free —OH groups thereon in an organic solvent under a reflux condition; and forming an aryl sulfonic acid-functionalized solid by sulfonating the aryl-functionalized solid by a sulfonating agent.
