A new transfer hydrogenation of 2-nitrotoluene with methanol to 2-methylaniline was successfully implemented. The transfer hydrogenation of 2-nitrotoluene with methanol showed much faster rate than its hydrogenation with hydrogen over X zeolites. Based on the reaction results over different modified X zeolites and activated carbon, a radical mechanism was proposed. Graphical Abstract .
The porous alumina catalysts with different acidity were prepared and tested for dehydrofluorination of 1,1,1,2-tetrafluoroethane to synthesize trifluoroethylene. The XRD, BET, SEM, NH3-TPD and py-IR techniques were used to characterize the alumina catalysts with different calcination temperatures. The porous θ-Al2O3 showed the excellent catalytic performance, with 35.1 % conversion and the selectivity...
