摘要:
采用浸渍焙烧法制备负载磷钨酸(PTA)催化剂用于以苯酐和乙基苯为原料,氯苯为溶剂合成2-(4’-乙基苯甲酰基)苯甲酸(BEA)的反应中.实验结果表明,当PTA负载量为30%(质量分数),焙烧温度为300 ℃时,以SiO2为载体负载PTA后,其催化活性增加逾一倍.实验采用XRD对负载量的影响、NH3-TPD对焙烧温度的影响进行了分析,用FT - IR和 BET对PTA/SiO2催化剂进行了表征.考察了PTA/SiO2催化剂的重复使用性能,结果表明,PTA/SiO2在重复使用后仍保持了原有的催化活性.
Abstract:
PTA supported catalyst was prepared by dip roasting method for the synthesis of 2-(4’ -ethyl benzoyl) benzoic acid (BEA) from phthalic anhydride and ethyl benzene as raw materials and chlorobenzene as solvent.The experimental results showed that when the load of PTA was 30%(mass fraction) and the roasting temperature was 300℃, the catalytic activity of PTA was more than doubled with SiO2 as the carrier.The effects of XRD on loading capacity and NH3-TPD on calcination temperature were analyzed. Ft-ir and BET were used to characterize PTA/SiO2 catalysts.The reuse performance of PTA/SiO2 catalyst was investigated, and the results showed that the original catalytic activity of PTA/SiO2 was still maintained after repeated use.
