abstract={Alcohol is one of the functional groups detected as part of qualitative organic analysis. The final identification of alcohol involves the preparation of suitable crystalline derivative, usually the 3,5-dinitrobenzoate. According to the standard procedure, 3,5-dinitrobenzoic acid is first converted to 3,5-dinitrobenzoyl chloride by reaction with either phosphorous pentachloride (PCl<SUB>5</SUB>) or thionyl chloride (SOCl<SUB>2</SUB>). However, in this reaction, hazardous side products like phosphorous oxychloride (POCl<SUB>3</SUB>), hydrochloric acid (HCl) and sulphur dioxide (SO<SUB>2</SUB>) are produced. In the present method, we report the direct and benign conversion of alcohols to the corresponding 3,5-dinitrobenzoates using ionic liquid, (bmim)HSO<SUB>4</SUB> under microwave irradiation.},
