Acetylsalicylic acid ＂new use for an old drug＂ application status and application prospect were analyzed in detail. Compared with the present market of acetylsalicylic acid synthesis methods advantages and disadvantages. Design suitable for industrialization of better synthetic route. The effect of raw material ratio, the dosage of catalyst, reaction temperature, reaction time on the yield of the reaction, further optimization of the synthesis technology. Through the experimental data processing and analysis, the O acylation reaction conditions for synthesis of acetyl salicylic acid： without water environment, concentrated 4-Toluene sulfonic acid as catalyst, n（salicylic acid）＂ n（acetic anhydride）=l ： 2.0; when the reaction temperature of 85 ℃ and reaction time of 30 min, acetyl salicylic acid yield were higher than 97 %. The sample meets acetylsalicylic acid quality requirements of＂Chinese Pharmacopoeia＂ and ＂with the United States Pharmacopoeia＂, can be used for the synthesis of acetyl salicylic acid.
