ABSTRACT OF THE DISCLOSURE p-toluic acid and alkylene oxide are produced simultaneously in high yields by epoxidizing a lower olefin such as ethylene or propylene with per-p-toluic acid in the presence of 10 to 1000 ppm by weight, preferably 50 to 500 ppm by weight of at least one of 8-hydroxyquinoline, dipicolinic acid, and pyridine- 2,6-dimethanol, as a stabilizer for peracid at a reaction temperature of 30° to 120°C, preferably 40° to 100°C. Per-p-toluic acid is in the form of a solution containing 10 to 50% by weight of per-p-toluic acid.
