乙氧基扑炎痛的紫外分光光度测定

Determination of etersalate by UV spectrophotometry

乙氧基扑炎痛为乙酰水杨酸的衍生物,其抗炎解热作用优于阿司匹林。经用0.1mol/L氢氧化钠溶液于100℃水解15min,于293nm波长处量,获得了满意的结果,并对水解机理进行了探讨。

Etersalate is one of the new derivatives of the acetylsalicylic acid and also is a more effective analgesic anti - inflammatory and antipyretic actions etersalate can be quantitatively determined by UV spectrophotometric method at 293nm after treatment with 0. 1mol/L sodium hydroxide solution at 100℃ for 15 minutes.There is a linear range from 14. 4 to 72μg/ml(r = 0.99998). Optimum conditions for the concentration have been thoroughly investigated.The method is, simple, valid, accurate.
