Preparation of 4-nitrophenetole
Preparation of 4-nitrophenetole
To prepare the 4-nitrophenetole, 0.25 g gramequivalent of metallic sodium is dissolved in 300 ml of absolute ethanol to which the 4-nitrophenol, dissolved in a little absolute ethanol is then added. After the addition of the 0.2 mole of ethyl iodide (alternatively ethyl bromide), the mixture is heated under reflux with stirring and exclusion of moisture for 5 hours. The alcohol is distilled off from the reaction mixture to a substantial extent through a 20-cm Vigreux column with stirring and the cooled distillation residue is poured into 100 ml of 5% caustic sodium carbonate; the organic phase is extracted several times with diethyl ether, washed with water, and dried with calcium chloride; the solvent is distilled off, and the residue is fractionated at 112-115 °C/3 mm or recrystallized from ethanol/water. Unchanged 4-nitrophenol can be recovered by acidifying the aqueous alkaline solution and extracting it with ether. The yield of 4-nitrophenetole is 60%, m.p. 60°C.
