摘　　要：本文以胡椒醛为原料,用硝酸和乙酸酐作为硝化剂,采用正交实验法探索出了合成6-硝基胡椒醛的最佳反应条件,条件为胡椒醛2.0g、浓HNO(?)10ml,乙酸酐8.0ml,反应温度35℃,反应时间3.0h,此条件下6-硝基胡椒醛产率可达79.2%。This paper discusses the optimum conditions of making 6-Nitropiperonal by orthographic synthesis using Piperonal as the original substance and Nitric Acid and Acetic Anhydride as the Nitratiny agent These conditions, under which the yield rate of 6-Nitropiperonal can reach 79.20%, are shown as the following: Pineronal 2.0g, dark HNO ,10.0ml, Acetic Anhydride 8.0ml, reaction temperature 35℃. reaction time 3.0h.
