摘　　要：以钨酸钠、硼酸为原料,利用常规溶液合成法制备硼钨酸盐K_8[BW_(11)O_(39)H]·13H_2O,借助傅里叶红外光谱仪(FT-IR)、扫描电镜仪(SEM)、程序升温脱附仪(NH_3-TPD)对其结构进行了表征,并将其应用于催化果糖脱水制备5-羟甲基糠醛(5-HMF),系统考察了各因素对反应性能的影响。结果表明:硼钨酸钾呈团聚体的不规则块状结构且具有一定的酸性,在反应温度150oC、反应时间150 min、催化剂用量20 mg、二甲基亚砜作为溶剂的条件下,5-HMF产率可达35.5%,且重复使用3次仍保持较高的活性。With sodium tungstate and boric acid as raw materials, a tungstoborate catalyst K8[BW（11）O（39）H]·13H2O was synthesized by conventional solution method, Fourier transform infrared spectrometer（FT-IR）, scanning electron microscopy（SEM） and ammonia temperature programmed desorption（NH3-TPD） were used to investigate the structure. Futhermore, the catalyst was used in research of catalytic conversion of fructose to 5-hydroxymethylfurfural, and the effects of factors were studied. The tungstoborate showed an irregular block structure with a certain acidity, and 35.5% of 5-HMF yield was obtained while dimethyl sulfoxide as solvent, 20 mg catalyst with 150 ℃ for 150 min. The catalyst also exhibited excellent catalytic stability within three times reused.
