摘　　要：本文以实验室自制催化剂AFS,采用气相催化固定床工艺,对萘空气催化氧化制备1,4-萘醌的工艺进行研究。优化工艺条件得到最佳反应温度395℃,反应空速在35 g/L·h,此工艺条件下原料转化率≥95%,1,4-萘醌的收率≥45%。With catalyst AFS,1,4-naphthoquinone was synthesized from naphthalene by gas-catalytic oxidation using a fixed bed. The optimum conditions were temperature 395 ℃,space velocity of naphthalene 35 g / L·h. In the condition,the conversion rate of naphthalene was above 95% and yield of 1,4-naphthoquinone was above 45%.
