V2O5/TiO2上甲醇催化合成甲酸甲酯

摘要

报道了采用共沉淀法制备的复相催化剂V2O5/TiO2进行甲醇气固相氧化合成甲酸甲酯的研究结果,探讨了催化剂配比、原料配比、反应温度等因素对反应结果的影响,并对催化剂进行了X射线衍射分析测试。结果表明,适宜的操作条件为催化剂配比V/Ti=1(原子比)、n(CH3OH)∶n(O2)=1、反应温度为165 ℃、空速3 600 h-1。该体系催化剂具有较好催化活性和稳定性,具有工业化前景。%The synthesis of methyl formate from methanol have been studied under continuous stable conditions via gassolid phase reactor on a composite catalyst (V2O5/TiO2) prepared by coprecipitation method. The optimum conditions of the reaction were obtained, and the influence factors, such as the V/Ti(a.r.), reaction temperature, space velocity, and moloratio of methanol/oxygen etc. have been discussed.
