Hydrophobic Lurylamine Modified Heteropoly Acid as an Efficient and Recyclable Catalyst for the Hydrolysis Reaction in Aqueous Solution under Microwave
Qingdao Technical College, Qingdao, Shandong Province
A new modified phosphotungstic acid (HPW) catalyst (HPW-catal) was synthesized b y a simple mixing method under ambient atmosphere and evaluated for the hydrolysis of sucrose and ethyl acetate under microwave irradiation. The as-synthesized catalyst was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy(FTIR), and NH3-TPD, which proved that HPW was sucessfully modified with lurylamine and the catalyst still remains the Keggin structure. Significantly, the HPW-catal showed excellent catalytic hydrolysis perforance for the sucrose and ethyl acetate under microwave irradiation. Both of the reactions were studied over other solid acid catalysts, such as AM-15 and ZSM-5. At mild tempretures, the sucrose and ethyl acetate could be hydrolyzed into corresponding products. The maximum glucose yield and alcohol could reach 100% and 95%, respectively. The HPW-catal can be recycled and reused. The HPW-catal will provides new ideas for the modifying of heteropoly acids.
