HCID 47654-Hydroxybenzenesulfonic acid

Procedure

In this embodiment, PholTMS was grafted onto silica gel to form phenol-functionalized silica gel, which is denoted by Phol-SiO2. Then, phenol-functionalized silica gel was sulfonated by concentrated H2SO4 to form phenolsulfonic acid-functionalized silica gel, which is denoted by PholSO3H—SiO2.
