摘要
The preparation, characterization, and catalytic properties of acid treated clay (ATC) are reported. ATC has been characterized by XRD (basal spacing, 14.82 ), specific surface area (66 m(2)/g), pore volume and pore width using BET method, UV-Vis DRS, TGA, SEM, and surface acidity by TPD of NH3. The activity of was investigated by the reaction of benzil with o-phenylene diamine. Among the catalysts, ATC was found to be more active. The reaction of various substituted o-phenylenediamines with benzil was studied on ATC to obtain corresponding quinoxalines in good yields. The regeneration and reusability of ATC has also been investigated.
