Abstract

Molybdovanadophosphoric anion (H 2 PMo 11 VO 40 2 − ) room temperature ionic liquid was prepared and characterized by the methods of FT-IR and TG. Then, this ionic liquid was employed as catalyst for the oxidation of benzene to phenol by H 2 O 2 without using solvent. The homogeneous emulsion formed by the catalyst and substrates during the reaction facilitated the catalytic process. After reaction, the catalyst could self-precipitate from the reaction media and proved to be recyclable.

Abstract

Abstract: Basic ionic liquid functionalized mesoporous silica SBA-15 was prepared and characterized by XRD, N2 adsorption–desorption, FT-IR and TEM. The catalyst demonstrated to be an efficient heterogeneous catalyst for olefin epoxidation using H2O2 as oxidant. The catalyst could be recycled at least five times without appreciable loss of catalytic activity. [Copyright &y& Elsevier]
