Synthese

224 grams of V2O5 was added to a solution consisting of 490 ml of water 468 grams of oxalic acid at a temperature of 80 to 90C, stirred thoroughly, and reacted to obtain a vanadium oxalate solution.
1250 g of SiO2 silica sol at a weight percent concentration of 40% SiO2 was slowly added to the above solution under stirring, and then a solution comprising 864 g of Cr(NO3)3-9H2O, 12.4 g of KNO3 and 500 ml of water, 76.4 g of H3BO3, 85.1 g of 85% phosphoric acid and 500 ml of water and 43.5 g of (NH4)6Mo7O24-4H2O and 100 ml of water were composed of a solution, stirred, heated and evaporated to a solid content of 40% by weight to obtain a viscous slurry.
After the above slurry was formed by spray drying, the catalyst precursor was pre-roasted at 300C for 2 hrs, and then roasted at 650C for 5 hrs to obtain a catalyst composed of atomic ratio: V1.00Cr0.9B0.50P0.30Mo0.10K0.05/SiO2, and the catalyst main loading weight ratio was 50/50.
Property Evaluation of Catalyst Processes Conditions: p-chlorotoluene: ammonia: air = 1:4:25 (molar), catalyst weight loading (WWH) 0.05 h-1, reaction temperature 420 , reaction pressure 0.01 MPa.
Results: p-chlorotoluene conversion 99.6% p-chlorobenzonitrile selectivity 91.5 %, p-chlorobenzonitrile conversion 99.6% p-chlorobenzonitrile selectivity 91.5% p-chlorobenzonitrile conversion 99.6% p-chlorobenzonitrile conversion. nbsp;91.5% p-chlorobenzonitrile yield 91.1%.
