Abstract: Sorption and desorption of two neutral, nonpolar organic compounds, 1,2-dibromoethane (EDB, a soil fumigant) and trichloroethene (TCE, an industrial solvent and common ground-water contamina...
Reactivity of Anisoles on Clay and Pillared Clay Surfaces
Anisoles Bentonite Catalysis Fluorhectorite Montmorillonite Nuclear magnetic resonance Pillared clay Quinones
2012/1/4
Pillared bentonites were found to be efficient catalysts for the O-methyl bond cleavage of anisoles (e.g., m-methylanisole, guaiacol, and creosol) under very mild, static conditions (150亱C, a few hour...
