MIL-101(Fe)负载型催化剂催化合成砜吡草唑
Synthesis of pyroxasulfone over MIL-101(Fe) supported catalyst
MOF materials with ammonium molybdate tetrahydrate supported by different metals (Fe,Cr,Cu) are prepared via hydrothermal method,and characterized by means of XRD,FT-IR,SEM,EDS,TG and BET.The impacts of raw material feeding ratio,reaction temperature,reaction time and solvent type on the synthetic reaction of pyroxasulfone are explored.Results show that the prepared Mo@MIL-101(Fe) material exhibits excellent effect on catalytic oxidation synthesis of pyroxasulfone.Both the conversion rate and yield of the reaction are the highest,being 99.18% and 97.32%,respectively when methanol is used as the reaction solvent,Mo@MIL-101(Fe) is served as the catalyst,the feeding ratio of raw materials is 1∶3,reaction temperature is 55℃ and reaction time is 4 h.
