摘　　要：采用八水合氧氯化锆和氨基三亚甲基膦酸(ATMP)合成有机膦酸锆(ZrATMP),进一步负载Cu组分制备Cu/ZrATMP催化剂,考察催化剂制备条件及其催化糠醛一锅法合成γ-戊内酯性能。结果表明,ZrATMP具有Lewis/Br nsted酸性中心,但催化糠醛合成γ-戊内酯反应活性较低。负载Cu组分能形成强酸中心,并进一步增强Lewis酸位点。与ZrATMP相比,Cu/ZrATMP同时具有Cu金属中心和Lewis/Br nsted酸性中心,表现出更高的糠醛合成γ-戊内酯反应活性。Zirconium organophosphonate(ZrATMP)was synthesized using zirconium dichloride oxide octahydrate and nitrilotris(methylene)-triphosphonic acid,and then Cu component was loaded to prepare Cu/ZrATMP catalyst.The effects of the preparation conditions for catalyst and the catalytic performance of the catalyst in the one-pot conversion of furfural to γ-valerolactone were studied.The results showed that ZrATMP with Lewis acid and Br nsted acid sites exhibited extremely low catalytic activity for the conversion of furfural to γ-valerolactone.The loading of Cu component caused the formation of a strong acid center and further enhanced the Lewis acid sites.Compared with ZrATMP,Cu/ZrATMP with the Cu metal center and the Lewis/Br nsted acid center exhibited higher catalytic activity for the conversion of furfural toγ-valerolactone.
