Synthesis of phenyloxirane

Preparation of phenyloxirane

Preparation of phenyloxirane

Preparation of phenyloxirane

Styrene (30 g, 0.29 mole) is added to a solution of peroxybenzoic acid (42 g, 0.30 mole) in chloroform (500 ml), and the mixture is set aside at 0° for 24 hours, being repeatedly shaken during the first few hours. Completion of the oxidation can be determined by titration of an aliquot part of the chloroform solution. Then the benzoic acid formed and the small excess of peroxybenzoic acid are removed by repeated extraction with 10% sodium hydroxide solution, and the organic phase is washed with water until free from alkali and then dried over sodium sulfate. Fractional distillation affords styrene oxide (24-26 g, 70-75 %) as a colorless liquid, b.p. 101° C/40 mm.
