Partially and fully sulfonated UiO66 derivatives, along with the non-functionalized MOF, were synthetized by one-step solvothermal synthesis. Structural, acid and porous properties were investigated before and after dehydration and thermal activation processes. Hydrated, dehydrated and thermally activated materials were screened as a heterogeneous catalyst towards the esterification of levulinic acid with ethanol in order to determine the effects of the exposed acid functionalities amount and hydration. The hydrated fully sulfonated UiO66 presented the highest activity and resulted to be more efficient than commercial Amberlyst 15. It also demonstrated high stability and recyclability in consecutive reaction runs.

全磺化水合UiO66作为酯化生产乙酰丙酸乙酯的有效催化剂

通过一步溶剂热合成合成了部分和完全磺化的UiO66衍生物,以及未官能化的MOF。在脱水和热活化过程之前和之后研究了结构,酸和多孔性质。将水合,脱水和热活化的物质筛选为乙酰丙酸与乙醇酯化的非均相催化剂,以确定暴露的酸官能度和水合的影响。水合的完全磺化的UiO66表现出最高的活性,因此比市售的Amberlyst 15更有效率。它在连续的反应运行中也显示出高稳定性和可回收性。
