SYNTHESIS OF 1-( ACETYLSALICYLYL) BENZOTRIAZOLE AND ITS REACTION WITH POLYVINYL ALCOHOL
1-(乙酰水杨酰)苯并三氮唑的合成及其与聚乙烯醇的反应

l-(Acetylsalicylyl) benzotriazole, a new active amide of acetylsalicylic acid has been synthesized either from acetylsalicylic acid and benzotriazole using DCCI as condensation agent or via acetylsalicylyl chloride and benzotriazole in the presence of triethyla-mine. The obtained active amide reacted readily with the hydroxyl group of PVA to produce the acetylsalicylyl ester of PVA.
