摘　　要：以空气为氧化剂,在光照射状态下,光催化氧化天然苯甲醛制备天然苯甲酸,重点考查了温度和时间对苯甲酸收率的影响。在自制的1L光氧化反应器中,反应温度75℃,反应时间12h,天然苯甲醛转化率达到50%以上,苯甲酸选择性超过98%。Natural benzoic acid was prepared by catalytic oxidation of natural benzaldehyde with air accompanied with irradiation by light.The effects of reaction temperature and reaction time were studied.The conversion of benzaldehyde was over 50%after 12h at 75℃,selectivity of benzoic acid was about 98%.
