| Abstract: | Using(NH4)2WO4 as W source,the catalyst W-HMS was prepared by in-situ method,and was characterized by XRD and FTIR.Then,catalyst W-HMS was applied to synthesis of glutaraldehyde,and the influence of major factors on yield of glutaraldehyde were investigated.The optimal synthetic reaction conditions were obtained through orthogonal experiment as follows:solvent was t-BuOH,reaction temperature of 35 ℃,reaction time of 28 h,catalyst amount of 3.4979 g,and the yield of glutaraldehyde was up to 78% under above conditions.XRD Characterization showed that catalyst W-HMS had characteristics of mesoporous zeolite structure;FTIR spectra showed that W species were introduced into the framework of the HMS mesoporous molecular sieves successfully. |
