摘要
实验制备了硼钼酸盐,并通过XRD,IR对样品的结构进行了分析,通过热重(TG)对样品的热稳定性进行了分析。以苯甲醛为原料,过氧化氢作氧化剂,以[(CH_2)_5NH_2]_5BMo_(12)O_(40)为催化剂,考察了催化剂用量、物料配比、反应时间、反应温度对产物收率的影响。确定最佳反应条件:n(催化剂):n(苯甲醛)=1.847×10^(-3):1;n(H_2O_2):n(苯甲醛)=4.70:1;反应温度80℃;反应时间4h。苯甲酸的收率达到85%以上。
Boron-molybdenum acid salt [（CH2）5NH2]5BMo（12）O（40） was prepared, and it was characterized by XRD,IR and TG. Using benzaldehyde as raw material, hydrogen peroxide as the oxidant, [（CH2）5NH2]5BMo（12）O（40） as the catalyst, benzoic acid was prepared. Effect of catalyst dosage, reactants proportion, reaction time and temperature on the yield of benzoic acid was investigated. The optimal reaction conditions were determined as follows： n（catalyst）：n（benzaldehyde）=1.847×10^-3：1, n（H2O2）︰n（benzaldehyde）=4.70︰1,reaction temperature 80℃ and reaction time 4h. Under above conditions, the yield of benzoic acid can be above 85%.
