| 摘 要： | In this work,we synthesized tin(IV)phosphonate(SnBPMA)and zirconium phosphonate(ZrBPMA)by the reaction of SnCl4·5H2O or ZrOCl2·8H2O with N,N-bis(phosphonomethyl)aminoacetic acid,which was synthesized from a biomaterial glycine through a Mannich-type reaction.The SnBPMA and ZrBPMA were very efficient heterogeneous catalysts for the dehydration of fructose to produce 5-hydroxymethylfurfural(HMF),and the SnBPMA had higher activity than the ZrBPMA.The effects of solvents,temperature,reaction time,and reactant/solvent weight ratio on the reaction catalyzed by SnBPMA were investigated.It was demonstrated that the yield of HMF could reach 86.5%with 1-ethyl-3-methylimidazolium bromide(Emim]Br)as solvent,and the SnBPMA and SnBPMA/Emim]Br catalytic system could be reused five times without considerable reduction in catalytic efficiency.Further study indicated that the SnBPMA and ZrBPMA inEmim]Br were also effective for the dehydration of sucrose and inulin to produce HMF with satisfactory yields.

| Abstract: | In this work, we synthesized tin(IV) phosphonate (SnBPMA) and zirconium phosphonate (ZrBPMA) by the reaction of SnCl4·5H2O or ZrOCl2·8H2O with N,N-bis(phosphonomethyl)aminoacetic acid, which was synthesized from a biomaterial glycine through a Mannich-type reaction. The SnBPMA and ZrBPMA were very efficient heterogeneous catalysts for the dehydration of fructose to produce 5-hydroxymethylfurfural (HMF), and the SnBPMA had higher activity than the ZrBPMA. The effects of solvents, temperature, reaction time, and reactant/solvent weight ratio on the reaction catalyzed by SnBPMA were investigated. It was demonstrated that the yield of HMF could reach 86.5% with 1-ethyl-3-methylimidazolium bromide (Emim] Br) as solvent, and the SnBPMA and SnBPMA/Emim]Br catalytic system could be reused five times without considerable reduction in catalytic efficiency. Further study indicated that the SnBPMA and ZrBPMA in Emim]Br were also effective for the dehydration of sucrose and inulin to produce HMF with satisfactory yields. |
