摘　　要：以三氧化二钒为钒源,在体系中引入氧化剂和水夹带剂,合成了乙酰丙酮氧钒,实现了乙酰丙酮氧钒的绿色连续合成。探讨了空气、过氧化氢和氧气3种氧化剂对乙酰丙酮氧钒合成的影响,对产物进行表征并与商业乙酰丙酮氧钒对比。结果表明,引入氧化剂后,乙酰丙酮氧钒的产率显著提高,3种氧化剂制得的乙酰丙酮氧钒产率均可达到80%以上,其中氧气氧化效果最好,当氧气流量为200 mL/min,回流2 h时,乙酰丙酮氧钒产率可达90%。XRD、FTIR和TG结果显示,该文合成的乙酰丙酮氧钒与商业乙酰丙酮氧钒纯度相当。VO（acac）2 was synthesized from V2O3 in the present study.In the synthesis process,three oxidizing agents,including air,O2,and H2O2,and toluene,as a kind of water entrainment agent,were introduced to facilitate the reaction in order to realize the continuous green synthesis of VO（acac）2.The effects of the oxidizing agents were investigated and the obtained VO（acac）2 was compared with commercial VO（acac）2.The results show that the introduction of those oxidizing agents significantly increased the yield of VO（acac）2,which could on average reach more than 80%.O2 was found to be the most efficient oxidizing agent.The yield of VO（acac）2 could reach 90% when O2 flow rate was 200 mL/min and reflux time was 2 h.XRD,FTIR and TG results show that the VO（acac）2 synthesized through the process described in this paper is of high purity and is comparable to commercial VO（acac）2.
