摘要:以甘氨酸、磷钨酸为原料,在水溶液中采用一步法合成出氨基酸功能化杂多酸盐[Gly]3PW,并采用NMR、
MS、FT-IR以及XRD等手段对其结构进行了表征。考察了其在正十二醇与乙酸酯化高选择性合成乙酸正十二酯反
应中的催化性能。结果表明,在n([Gly]aPW)/n(正十二醇)=0.002、n(乙酸)/n(正十二醇)=2.0、反应温度
373K和反应时间7h条件下,正十二醇转化率和乙酸正十二酯选择性分别达到98%和100%,且整个反应过程无
需加入任何溶剂,[Gly]3PW显示了良好的催化性能。[ Glyla PW是一种有潜力的新型有机-无机杂化酯化催化剂。

Abstract: A new amino-acid functionalized heteropoly tungstate [ Gly ], PW was prepared in water
via one-step synthesis method with glycine and phosphotungstic acid as raw materials. The
structure of [Glyl, PW was characterized by NMR, MS, FT-IR and XRD Its catalytic performance
in direct esterification of acetic acid and dodecanol to dodecyl acetate was studied
the
optimized reaction conditions, that is, n(Gly] PW)/n(dodecanol)=0.002, n(Acetic acid)/
n(Dodecanol )2. 0, reaction temperature 373 K, reaction time 7 h and solvent-free, a high
conversion 98% of dodecanol was achieved with 100% selectivity for dodecyl acetate, whicl
demonstrated that [Gly], PW was a very potential organic-inorganic hybrid catalyst
