Acetyl salicylic acid was synthesized by the method of microwave radiation, Acetyl chlorine and salicylic acid were used as raw materials, iodine was used as catalyst. The amounts of acetyl chloride, iodine and catalytic time of microwave were investigated on the yield of acetylsalicylic acid, the best test conditions were obtained by orthogonal experiments furthermore. In order to investigate the quality of the products, the products were then applied at the bud of soybean seed. The factors that affect the yield of acetyl salicylic acid are: acetyl chloride (A) >catalytic time of Microwave (C) >catalyst of iodine(B), the amount of salicylic acid is 2.7 g, the amount of acetyl chloride is 2.4 mL, and the amount of iodine is 0.4 g, The catalytic time of microwave is 50 s at 800 W. Under the above test conditions, the power of acetylsalicylic acid was obtained with the yield of 64.52 %, it is odorless and slightly sour.
