【摘要】The epoxidation of methyl oleate (MO) was conducted in the presence of aqueous H2O2 as the oxi-dant and hierarchical TS-1 (HTS-1) as the catalyst; the catalyst was synthesized using polyquater-nium-6 as the
mesopore
template.
The
effects
of
various
parameters,i.e.,H2O2/C=C molar ratio,oxidant concentration,amount of the catalyst,reaction temperature,and time,were systematically studied. Furthermore,response surface methodology (RSM) was used to optimize the conditions to maximize the yield of epoxy MO and to evaluate the significance and interplay of the factors affect-ing the epoxy MO production. The H2O2/C=C molar ratio and catalyst amount were the determining factors for MO epoxidation,wherein the maximum yield of epoxy MO reached 94.9% over HTS-1 under the optimal conditions.%当今时代,资源短缺、环境污染等问题日益严峻,生物质资源化学转化利用成为各国研究重点,以生物质资源代替化石资源、以生物基材料代替石化材料,为发展绿色经济、循环经济奠定了基础.植物油资源由于其广泛的可获得性、固有的生物可降解性、低成本及突出的环境效益受到广泛关注.其中,环氧化的植物油作为可再生原材料应用于生产热塑材料的增塑剂和稳定剂、生物润滑油、涂料、粘合剂、化妆品及各种聚合物材料 (聚酯、聚氨酯、聚酰胺等).目前,
