| Abstract: | Deriving ethyl benzoicate and ethyl saliylicate from benzoic acid and salicylic acid in tinea pedis and taking n-dodecane as internal standard. benzoic acid and salicylic acid are determinated by GC. The best volumes of ethanol and sulphuric acid. The best separation and condition are getted by experiment. The date proves that the method is accuracy rapid and simple. with good reproducibility and recovery. |
