Mg–Al hydrotalcite catalysts with different Mg/Al molar ratios (0.6, 1.4, 2.2, 3.0) were calcined and tested in liquid-phase Michael additions at room temperature. The catalysts and pure oxides (MgO and Al2O3) were characterized by XRD, XPS, N2 ads

Sulfated zirconia (SZ) exhibits a high catalytic performance in the benzoylation of 1-methoxynaphthalene. Therefore, it was used as heterogeneous catalyst in the acylation of methoxynaphthalenes, methylnaphthalenes, naphthalene, and anthracene with b

H–D tracer experiments during n-octane aromatization on Cr2O3/La2O3/ZrO2 catalysts allow conclusions to be drawn on the reaction mechanism. The rate-determining step is the dissociative adsorption of the paraffin molecule. The following dehydrogena

Sulfated zirconia (SZ) has been found to have a high performance in the benzoylation of anisole. Thus, several aromatics were reacted with benzoic anhydride, benzoyl chloride, and acetic anhydride as acylating agents on SZ, to give the corresponding
